Don't think that you mentioned it, but for the people shooting with a one-shot-color or DSLR there's a variant called Bayer Drizzle or CFA Drizzle that avoids the interpolation that is part of debayering a color image for a bit more detail (at the cost of noise, as usual with drizzling). Both APP and PixInsight can do this.
Thanks for the tip Benny!
"I'm broke, partly due to Pixinsight..."
Oh I can relate..
We’ve all been there :)
Yep, Pixinsight costs an arm and a leg, but on the bright side, it is IMO, the best processing software out there, and, it is a one of license rather than ongoing annual subscriptions.
Agree 4000%
Very easy to understand video! Thank you.
Thanks Dylan - what an excellent set of videos on drizzle etc.
Thx mrtheoden!
Thank you Dylan
Thanks to you, I now dither and drizzle :)
Cheers
I have been using Pixinsight for a very long time. I started when it was free. I found that if you want to do drizzling it helps to build a PC that can crunch a ton of data fast. I found an old desktop running dual xeon processors, that seemed to do the trick. In the end I found that drizzling was easier using Nebulosity and the results are the same.
LMFAO!!! I still can't pull the trigger on pixinsight! I actually choked on my food you made me laugh so hard!!! Too funny 😂
Haha my work here is done.
That's awesome mate, really nice summary of a complicated topic. Can't wait to get some data of my own to try out these techniques. Enjoy NEAF!
Thanks Cap'n !
Love ur work Dylan!!
Thanks Thunder!
Wow! Thanks so much for the shout out for MBO and myself! We'd really love to entertain you there if you ever make your way down south :D Great video! I knew it was coming so I was looking forward to it :)
No worries Neil! Hope to get down there sometime :) Thanks for the shares too!
Currently using drizzle integration for my Pinwheel data, can't wait to see how it turns out!
Man you're crack up haha. Love your work!
Ibnul Hussaini 😆😊
Dylan, good processing technique. I knew the concept, but never tried.. thanks for detailed step by step. Will try some time.
No worries Ray!
Great video Dylan. I use drizzle on my 3.17 Arc Secs Per Pixel scale. Makes a huge difference to the stars, BTW I use to watch you on the Global Star Party, they were the days!
That’s going back a while! Would be nice to do something similar again :)
I like the humor
Thanks James! 👊🏼
Hey Dylan! Hope youre doing really well. i just wanted to say that im a huge fan of your channel and been watching your videos since i got into deepspace and was super confused on everything. Youve put some good understanding on a whole lot of things space and program related into my life as well as saved me a ton of headaches.
Also i wanted to through out a huge request. I just got myself an ASI1600, filters, and got SGPro, Ive set up the plate solving which find my objects was always the biggest headache for me, so i figured plate solving would make the world of difference. My problem and issue now is EQMOD. I cant seem to set it up to save my life, ive tried like 5 times already and feel im at a road block. theres no youtube videos that are clear on it and everyone on cloudy nights just seem to fight about everything. Ive tried doing step by step instructions ive found online... with not much luck So... i was wondering if you would be awesome enough to take a youtube tutorial request on how to hook up, and set up eqmod to be able to plate solve or use other programs like cart du ciel and stelerium to move your mount. Thank you so much for your time and for your effort tot make content and educating us astronomers
Hey thanks Mack. That was definitely the point of the channel. I'm no expert but can share the little things I learn here and there. EQMOD is a great program but I no longer have a mount that supports it so I can't really do a video about it anymore. It's a bit fiddly to setup at first with the com port / ascom stuff but once it's running it's great.
Hey Dylan, sorry to comment on an old video. Thank you for the instructions. I've always dithered every third sub, how often do you need to dither to drizzle? I've never tried because most of my setups are closer to oversampled with the 294MC pro and 1600MM pro.
Thanks,
Charles
Thanks Dylan! I'll have to try this when (honestly if) the weather improves. I've heard that when oversampling it's good to drizzle integrate then run decently heavy decon. I'll let you know how it goes.
God I’m still waiting for a clear night! Look forward to your results !
Dylan, I really enjoyed seeing you flash my book on screen! Hey, I'm broke too, with the publisher paying well under 10%! ;-)
Haha! God of the Bible has appeared ! 😂 all us astronomers are broke :)
LOL The 2000 years later always makes me laugh out loud.
Great info as always mate ☺👍:)
Cheers bud :)
Great tutorial Dylan. 👍
Thanks man :)
Great initial vid on drizzle. Hope you can do a video on guiding with PHD2 with specific reference to how you control your mount from the PC. ST4 vs ASCOM and how you cable to your mounts ports. Thanks again for all your great vids.
Hey Louis! I have a PhD2 video that covers this. For eq6 mounts you use the USB shoestring cable.. for Celestron you can plug in the handcontroller to a USB cable.
There are a few things you can do to optimize your workstation, like hard setting the OS swap file, putting your application swap file on a different physical disk, and bumping the RAM, etc.
Interesting... will look into this process. BTW I use Nebulosity. AKA... Dave Brewer.
"I'm broke, partly due to Pixinsight..." - The only thing I can say to others is if you want it, the sooner you get it the larger your return will be since it has a lifetime license....
If we ever get clear skies again in Sydney, I’ll definitely tag you on Instagram :)
You’ve been a huge help to my journey! Plus it’s awesome to have a good Aussie you tuber! I’d love to buy you a beer sir!
Cool :) I’m happy to be compensated with beer anytime 😆
Love this channel, thanks so much Dylan! Im very new to Astro photography, bought and EQ6 -R mount to use with my Nikon Lenses to get started and its been cloudy ever since. No first polar alignment, not one sky pic..... Haha.. Its my fault its cloudy, sorry about that. Keep up the great work Dylan! Good luck in the big Apple :}
Hey thanks for leaving a comment Obie 1! I don't think I've seen your name before? Astronomy is an exercise in patience. Mother theresa aint got nothin on me these days.
Hey Dylan, thanks for your reply. :} Yes this is my first time comment on your channel. I have been going through all of your posts enjoying your images and techniques to get them. Great job. I have been a pro photographer for 10 years but this is a different level for me, a great challenge and images I have never taken. I have also been watching AstroBackyard with Trevor which is great and has a different setup different part of the world. I love you RAZA scope setups but seems like a lot more challenges to get all of ducks in a row to get great images. I appreciate the F stop in your scope and I personally only own lenses F2.8 and below. Im going to start with my Nikon F2 200mm on my D800 35mm sensor (cropped to 28mm) and see what I can get. Buying a scope will be a challenge with so much choice, advantages / disadvantages to consider. Thats so much for your channel, I am learning amazing amounts of knowledge in Astro photography. Keep up the great humour and I love your intro by the way. Cheers from Brisbane. :}

Stever's Narrow-band Imaging Channel 😂
I never knew what drizzle did before this. It also helped me regain native resolution after a DSS setting I had to use for a Ha image. So that's always cool. And since I had been listening to Metallica's 'Of Wolf And Man', I then thought of
"I dither,
Therefore I drizzle,
Harvest the Pixel,
Capture the nice round stars".
Harvetsorrrrr of pixelsssssss ... language of the dammmmmmmned!
@@DylanODonnell 😂😂 legend
Great video my friend. Your killin me no rasa update lol. Dying to see your review of focuser and settings in sgp. Take Care
This weather is killing me 😆
@@DylanODonnell same here lol
One thing to note is that even though DSLRs have high resolution and small pixel sizes, with a bayer filter in the way the distance between pixels ( sensitive to the same colour) is larger and you might be undersampling
Good point !
Hey man, thank you very much. You make it so simple. Wow! Can I suggest a video on sampling ?
Good suggestion :)
great Vid again! and thanks for the info, hope you can do a vid on using Drizzle in Deep Sky stacker for us Hobbos that have tom scrounge for free apps 😉
Hehe in astronomy we’re all hobos 👊🏼
haha the cost of this hobby makes us homeless vagabonds, Camera & Tripod over the shoulder and off to a dark sight!
keep up the good work and hope New York is a blast!
@@DylanODonnell
Hi Dylan! Great info! I normally use Batch Preprocessing script to make my stacking. It includes Dark, BIAS, Flat, and Light tabs to include all your images. It just does your stacking, star alignment, calibration, etc., all at once! :D There´s also a "Generate Drizzle Data" available there (which is ON by default) but I´m not sure if the final stacked image is drizzled. I imagine it should be at a higher resolution than the original light frames? The batch preprocessing script is on: "SCRIPT > UTILITIES > BATCH PRE-PROCESSING".
Good question .. I’d imagine you’d have to run the drizzle integration on the final stack and use those generated files.
@@DylanODonnell Ill look for those files again just to be sure! It´s a nice feature, specially for those who have a hyperstar and need more resolution on smaller objects.
I wish that pixi would run as fast as when you speed it up :D Great video!
I know right? Good lord it takes a long time!
Hi Dylan 😉
I'm kind of curious now. You talked about drizzle beeing very useful for deep sky images scaling up, for posters, prints and so on.
Using Pixinsight (which I think would be better than Registax) how will drizzle work on planets? Is it something possible and useful? Did you do or you're planning a video about it?
Thanks 🤙
Hey Dylan if it wasn't for your how to videos I would've given up on using Pixinsight and probably AP entirely, keep up the great work! I'm actually working on Thor's helmet at the moment and would like to know if you think I should also use deconvolution once I've used drizzle and finally like deconvolution is this applied to Luminance channel only?
Hey that’s great to hear :) I sometimes deconv but often just lean on sharpening and masking with PS for similar effects without overmanipulating the data... which is easy to do with a bad deconv. The Lum layer sometimes refers to a brightness layer and sometimes refers to a detail layer. You would only sharpen the detail layer. In fact the brightness and colour layers can be blurry and make the image less noisy that way.
@@DylanODonnell Thanks - will give drizzle a try and let you know how I go as soon as I get a chance to finish capturing Blue and Ha data!
@@DylanODonnell Hey Dylan, whilst waiting for clear skies I tried out drizzle and you can definitely see a difference especially with pixellation (40 x Lum subs), I'll post a quick screenshot on FB and tag you - thanks again! P.S. You were right about how long the drizzle process takes, had time to not only make a coffee but also popcorn for my daughter, lol!
good work
Thx Simon!
any chance of a complete beginners pix insight tutorial? I'm too heavily invested in Mac and have to resort to deep sky stacker on parallels
I think I have one! It's an older video but it's a literal beginners guide to the interface and first steps.
Have a canon 1300d should you drizzle using a ed72?
Huh, I'm surprised that I didn't come across this when I was researching cameras! Are there any downsides to drizzle? The benefits of a sensor with much larger pixels than what I have now would be awesome if you could do this with minimal negative effects
It’s no substitute for correct sampling but it offers an small but good improvement to simply upscaling the image in post and definitely helpfully when processing for prints or smaller targets generally :)
@@DylanODonnell seems like a fantastic tool, do you utilize it often?
I'm first. What up? Sean M. Really cool. Gotta try it
Hey mate :) notification squad? 😆👊🏼
I’m broke from Pixinsight, FPL-53 glass, encoders, deep cycle batteries, NB filters, attempted orthogonal alignment, late night munchies....partially.
Hehe the struggle is real :)
I hope that honey drizzle was from a local beekeeper! Ahh nevermind, it doesn't matter, nothing matters and we're all going to die, lol.
Heh yeh shop honey is not pure or local. I try to get it from the farmers market when I can and I’m not even a real hippy.
So am I correct in thinking with an ASI183MM, which has very small pixels (2.4) I would benefit when shooting shorter focal lengths (70mm) which would be significantly undersampled? This will be great as it is the one thing that is holding me back from pulling the trigger on the camera. P.S My coffee was lost 2 times during this video...well played sir!
Hehe another drinked spilled yesssss. Yes what your saying sounds right but drizzle in no substitute for good sampling generally, but it helps :)
Fo' shizzle my drizzle 😎👍
Hah!
Noice : ) hows your subscriber arduino thingy? Has it gotten old yet : p
It’s so good! I want to make it louder. About 30-50 subs a day and I’m asleep for half of them so it’s always a novelty.
I'll look for you at NEAF!
Great! Come say hi :)
How’s the nexdome dome on the sky shed pod working? See you at NEAF.
Good Larry! Needs a bit of WD40 and lube but functions well :)
Are you planning on adding the motors for the dome and shutter?
I’d love to .. but would probably get the nexdome walls for that. And no time soon with my financial situation!
Just started on the pixinsight trial, astro dudes tutorials have made it approachable. Are you saying here that drizzle is redundant if you're using a DSLR? I am dithering with APT.
All the theory and the literature says it works best for undersampled images *but* my images aren't undersampled and it still works great as an upscaler as long as you dither. Heaps of people use it anyway .. so I would say .. just try it and see :)
@@DylanODonnell tried it in the past with DSS, end up with final stacked image @1GB in size. Made it very slow to work with. I'll give it another go now I'm trying Pixinsight
Does Australia have a space program? If it does that will be news to me.
We have a space agency .. it’s brand new :) nasa is launching some rockets here !
Just tested this Drizzle Pixinsight idea and my final file was 923 MB and 10,963 x 7,532 Ouch !! BUT holy cow! details. the star were so high res, so was the background.. but get ready for 2-3 hours on integration on 30-60 subs of 38 MB bin 1x1 each .
I know right! Takes a lotta resources heh
@@DylanODonnell If your retired you got it made... fire it up and go a cold Molson Canadian... LOL
@@BrokenPik I'm retired and the wait time still annoys me when I drizzle, but it's very useful on small targets.
@@ChucksAstrophotography boy do i here you there .. i think i ll use it (drizzle) on my Meade DSI Pro II with subs of 852Kb. that should fix it .. ( time wise) LOL
Can you crop before running drizzle so that the file size and processing time is manageable
how do i know if my images are undersampled? Im using an 8" Edge HD with a 294mc Pro
Looks fine to me :) www.bintel.com.au/tools/astronomy-calculator/?focallength=2032&fratio=10&pixelsize=&xpixels=&ypixels=&eyepiecemm=&eyepiecefov=&binning=1&multiplier=1&target=moon&p1=&p2=&p3=&telescope=10047&camera=25294&eyepiece=&v=322b26af01d5
@@DylanODonnell ok cool. I also have a hyperstar so when I enter that in it looks like it will be slightly undersampled and I can use this drizzle technique! Thanks Dylan.
velcro was invented by the Vulcans :P
Isn’t this sort of “making up” the image? With half of the data inferred it starts to feel more like a painting than a photograph.
I haven't dithered, but I've prevaricated, is that OK?
Haha I learned a new word today!
Drizzle works best on lemon cake
hehe
Thanks for that.
... and remember, 50% of the nitrogen in our bodies has already been through a Haber-Bosch ammonia reactor. [a footnote you may not have previously used :P ]
I like it!
2 THOUSAND years later....
Sup with that pic dude?
Do you even Drizzle?
I cant focus on beginning of the video with the guy in the background on the tv going crazy.
Yeh that was silly!
What is your profession
I'm a lowly coder.
@@DylanODonnell👌, i am a accountant
So photochopping wasn't good enough so they invented more intense photochopping. Shall we call it photowizzing?
I understand you’re “broke”, but I hope you don’t get “fixed” for the sake of the next generation of astrophotographers!🤣.
I South Louisiana, drizzling can last for days or weeks, and is generally not good for astrophotography!☹️
Hehe I’ll keep filming if you keep watching 😆
Subscribe to pewdiepie. But also me.. k thx.
Oh, guess I am out. I have no patience.
Haha!
I just can't justify the price of Pixinsight. I have the money. I just won't pay it. AstroPixelProcessor works very well and it's much much cheaper!
I've heard good things about APP and PixInsight has it's fair share of quirks. I love it in my toolkit though.
@@DylanODonnell I'd love to see a MacOS version of the BLINK tool.
WTF, Where all NOT going to Die?
Not today hopefully :)
