Cosgrove's Cosmos
США
Добавлен 6 июл 2021
Astrophotography can be an awesome thing. Just think about it - an everyday person sets up some gear on their driveway and captures some photons that have been traveling for thousands, and in some cases, millions of years through the universe before they entered their telescope and were captured by their camera! You can create images that, until now, you only saw produced by professional observatories.
In 2019 I retired and started my journey into Astrophotography. It was a bit like Alice falling into the looking glass: Choosing gear, assembling it into a useful configuration, setting up, polar alignments, pate solving, meridian flips, camera cooling, focusing methods, binning, Sequence control, calibration frames, stacking, image preprocessing, & Image processing - it can make your head spin if not explode.
I finally sorted all of that out - and I plan to use this channel & my website to share my results & learnings.

Observatory Update: Roofing, Skins, and Test Opening the Roof!
This is the next video in the series documenting my observatory build!
In this video, the roof framing is completed, plywood cladding is applied and wrapped, and the windows go in.
Then, for the very first time, the roof is unbolted and tested out. The first roll attempt was a bit bumpy as we still had some rough aspects to the welds. Primarily where the V-track was welded together. These were ground smooth, and then the roof rolled easily and smoothly!
Next, we are doing the vinyl siding, the electrical work, and pouring the slab - so stay tuned!

Observatory Update: Testing the Rolling Roof for the First Time!
Просмотров 2289 часов назад
This video is a bit of a teaser reel - I am working on a new video highlighting the next phase of my observatory build - but this was a test run of the track system and roof opening. It is being opened with manual power - one of the builders is on a scaffold in the back of the building and moving it while walking on it. Very smooth, very quiet! Stay tuned for the full video!

Great progress, Pat. It's really looking nice!
Thanks, I'm pretty excited about how it's coming together!
Thanks for this! Can you explain how you rendered the range mask background completely black after removing the stars?
Glad it was helpful. To answer your question, please review my video "Using RangeSelection to Create a Subject Mask". This will show how to make a basic subject mask. But now you want to eliminate portions of the mask you don't want - say the stars - take a look at my video "Cleanup A Mask Part 2: Using CloneStamp" for how to do that. Hope that helps!
Great work , but for what cost in the end between materials and labor?
Let's say that it costs more than I like but less than it could have... :-)
It’s amazing how quick it goes up once the base was poured, it seems to be moving super fast now..👍🏻
Yes indeed. But it will slow down a bit now. I need to get some electrical work done before pouring the slab and installing the remaining parts of the drive system (linear drive gear, passive lockdowns, and manual lockdowns). This will require getting the right group of people together, so scheduling and weather will slow the pace a bit.
Going up fast! Nice.
Very!
Wow, that's an impressive sturdy roof! I can send you a pic of mine just for a (hilarious) comparison 😂
Thanks! Indeed - you can send it to my contact email at CosogrovesCosmos.com!
Wow, that is big, I could live in that 😂
I’ve gone over budget - I may have to live in it!
@@cosgrovescosmos 😂😂
Progress!! Really coming along nice!
Thanks! Hope we can finish it soon before the weather moves in!
Goals right here, thank you for the detailed updates, it's exciting from this end I can't imagine how this feels from your end!
Thanks so much! The project is proceeding rapidly, and I am currently working on a new video showing the completion of the roof, cladding of the walls, and testing of the roof opening. So stay tuned!
Great video - exactly what I was looking for as I have an FRA400 and have just purchase the newer version of the Pegasus rotator. A question though, do you have the reducer for the FRA400, and if so, is it still compatible given the requirement with the reducer to have exactly 55mm back focus. Other scopes have placed the rotator first, then the reducer, then the remainder of the imaging train to ensure the 55mm back focus. Of course, with the ASKAR FRA400 design that's not possible, but if I am intuiting your commentary correctly, then it should work too as your simply replacing one section of the conical adaptor and can use spacers to match the exact width?
I do have a reducer for my FRA400, but I have never used it. However, your description of my approach is right on! Get the back focus you need, then remove one of the conical sections and use the rotator and spacers to replace it. Good luck with your installation!
Wow! Impressive building. What a great observatory once finished! Mine looks like a doghouse in comparison 😂
Thanks much! This has been a long time coming after many years of setting up in the driveway! If your observatory lets you avoid that, it's golden - whatever its size or finish is!
Looking Great! Thanks for Posting the progress. Very Interesting watching it come together!
Thanks so much! I appreciate you watching!
Looking good Patrick! It will all come together very quickly now after that very long wait 👍
Thanks, Kevan! It is kind of surreal to see it coming together after planning it for so long!
What size roll off is this? Must be a pretty decent size to accommodate four mounts.
The building is 16 x 20 feet in size.
Wow, it’s really coming on now, starting to see how it will look, loving following this journey with you…great video as always..👍🏻
Thanks - it does seem to be moving fast now!
Still laughing! Your flight lasted longer than mine would of.😂
You gotta laugh! I called my son - who owns the drone - and said: "Ummm - hypothetical question. You have a drone stuck 40' up a tree - what would you do?". His comment, "Somehow, I don't think this is hypothetical - right?"
Every mistake is a learning experience! That's what I tell myself as the eyepiece hits the ground.
Sounds about right to me!
I was hoping to know more about elongated stars,does that mean the stars exposure to elements would be present.I Figured a way to share elongated Stars and energy to regenerate is to allow pine needles to absorb the nutrient from a Very Moist lawn,sometimes the stars appear in very Dry places to stabalize the elements this earth has produced.Configure this with simple green grass but it would be nice to ultimately use very sweet seeds not just a circle of maple syrup,pine needles,pine pollen,and Rocks..any type of rocks.the stars don't like watermelon as much because everyone trips,although its useful to add that nutrient to the Dry dirt under pulled grass or lawn clipping.if you don't like the sacred planets forming in the IC1848 SN from your own home the stars are travelling at night and that's when they cool off.thanks
Nice to see progress Sir
Thanks, it's been a long time coming! It's moving pretty fast now!
Thanks, it's been a long time coming!
Exciting stuff
The walls and steel are going up now and its starting to really look real! Super excited now!
Pat, you keep turning up on my Facebook to add as a friend. 1. How does it know? 2. Are you publishing information there as well or that’s just your personal page?
Excellent work! From a builders point of view of 38 years in construction and as an astrophotographer, who doesn’t love a good obsey build video😀 Looking forward to the next stage! My obsey is on a much smaller scale, only one pier, but wouldn’t be without it now! CS
Thanks so much! From a non builder perspective, I am love watching the process come together! I can’t wait to join your ranks and Finally have an observatory of my own!
Nice one, glad to see it moving forward again, seems like an age since you last update…👍🏻
Yup - the delays were driving me a little crazy for sure! Very glad to see the progress!
Thanks for this Mr Cosgrove ! This tool worked a treat on my ASI2600 MC Pro image with banding issues.
Thanks! Glad to hear it worked for you!
Thanks, just what I needed before Windows does another automatic update!
After calibrating frames you don't have to register and stack "manually " You can put calibrated frames back in WBPP without any calibration frames, and just check weighting, local normalization, registration and integration in the pipeline. As long as there are no calibration frames present it won't try to re-calibrate the frames. Also remember that if you're shooting OSC and you debayer as part of calibrating, you need to treat them as mono if you load them back into WBPP for integration.
Good tip! Thanks!
I wish you made a video for one shot camera process through astap grexpert Siril Ps
I mostly make videos about the tools and methods I personally use, and since I don't use some of the suggested tools, it is unlikely that I will get to that. Thank you for the suggestion. I may add an OSC to the mix at some point, so you may see that come along.
Great work
Thank you
Thank you for the tutorial!
Glad it was helpful!
Awsome setup!
Thanks Much!
Amazing video. Thank you very much :-)
You are welcome! Glad you found it helpful!
Thanks for a great video - I'll definitely add these options to my workflow!
You are most welcome! Glad you found it helpful!
That is badass! Can’t wait to see it come together.
Thanks! Me too!
They look really nice!!
Thanks so much!
Looking Good! Nice Color.
Thanks - I didn't want to go with the traditional Black or white...
Excellent…👍🏻
Thank you 👍
Same story. I ended up with 34 hours of data and still it wasn't enough to produce nice image. I used osc camera and think 100 hours is required to get good result. For me it's semi failed project.
Wow - 100 hours - for me - would be a 3-year project with our weather!
Very excited for you Pat!
Thanks! I am pretty pumped as well!
Looking good. Congrats on the progress!
Thanks! I am actually setting up my smaller scope on the pad tonight to image!
@@cosgrovescosmos Awesome. I think I'm near the same part of the world as you - I'm just east of Toronto. Can't believe we are getting 4, maybe 5 clear nights in a row. Scope is working overtime!
It is, indeed, LONG over due!
Are you planning on cutting any of those trees down or just looking at the zenith?
If you take a look at my previous posts, you can see the skyline better. In fact I just had tree work done that removed 7 large trees, 14 smaller trees, and bobbed some other. So it is now much better than it looks here, as my SE, S, SW, and NW horizons are pretty open. I am blocked to the North, but that is OK as the light dome of Rochester is there, and I will get those objects when they are higher in the sky. My East view is blocked by trees, but I can pick up targets as they get 40 degrees of elevation there. Compared to the narrow driveway view from my old place, this is heaven!
You must (have been) rich!
@@mikehardy8247 Well, they say the best way to become a millionaire when doing astrophotography is to start out as a billionaire! That sounds about right! So people retire and buya fishing boat. You know what I am spending my retirement on! 😃😃
Nice!! Going to be alot nicer than using the driveway! As always best wishes!
Thanks, Pete! Yes, it sure will beat the driveway!!!
What you had done in 2 days took three of us over several months of digging (rock hard soil)/trenching , leveling, adding gravel (lots of individual bags) rolling/compacting and later pouring hand carried, hand mixed bags (50 60lbs bags) of cement for the pier. Worth every joule of it! Then the real fun started when we built the observatory. I got a thrill out of watching your plan start to come together. You must be really charged up!
Just reading your account is causing the arthritis in my knees, back, and shoulders to flare up! Having done all of that - the rewards must be all the sweeter!
Looks like some great progress. Thanks for keeping us updated. You might just inspire me to get busy on my new location lol
Thank you! Hopefully, everything will move quickly now with little or no surprises!
This was excellent. I got lost a couple of times...that's on me, but this was very helpful in process development instead of the typical "click this and enter this".
Thanks much! BTW - Most of my imaging projects on my website have full, detailed, and annotated process walkthroughs if you think that might be helpful to you.
That looks like it's gonna be a BIG roll off!
Very exciting times…I bet it will move on pretty quickly now 👍🏻
Thanks - I hope all goes smoothly!
Excellent series and follows almost exactly my plans as well. Had originally thought I would go with the concrete foundation and with the cost estimate also decided to go with the pole barn design. I have an open 10 acres so just have to make my wife happy about where it is all going to go and with the hopefully soon decrease in the west Texas heat will start drilling some holes and filling them back up with concrete. Keep it coming and hope it does all come together in the next month or so for you.
Bruce, Thank you so much! I am a bit envious of your 10 acres of clear Texas skies, but I don't think I am as envious of your heat this time of year! Best of luck with your project, and I will keep my fingers crossed on mine. The excavator is due to break ground on Thursday of this week, weather permitting! Clear skies, pat
Thank you for the update. It's exciting to see what you are doing.
Thanks so much! I'm pretty excited to get this thing built... finally! :-)
Thank you for the tutorial...my version came out really good compared to what I did a couple of years ago. Clear skies!!!
So glad to hear that you found this useful!
Just what I was looking for. Thanks.
Glad I could help!
Enjoyed ur video. I have multiple mono cameras. I use a zero width 54MM adapter to directly attach my 2600MM to my EFW. I then can change cameras very quickly just by unscrewing the camera from the EFW body rather than removing 4 screws. Of course u need to leave tilt plate on. What do u think?
Thanks for your comment! If you can afford to leave the tilt plate on, this can be a great solution. I was concerned about whether my unmounted 36mm filters would vignette the field, so I wanted to absolutely minimize the distance between the sensor and the filter. I sacrificed the tilt plate and bolted the camera right onto the EFW, as you saw. This has turned out well for me. The mounting is solid, and I have no significant vignetting. I also did not need to use the tilt plate. I also tend not to shift my gear configuration around or change cameras. I treat the camera and EFW as a unit, and bolting them together works well for me. With your approach, you have a much greater ability to change cameras around. And you can use the tilt plate should you need it. The only downside I can see is that the camera can loosen its connection with the EFW and rotate a bit. I have run into this before myself. In the past, I set my scopes up in the driveway each night for imaging, so the rig's movement may have caused this. Clear Skies, Pat
