Great video John. You've really made it clear when and where to use each focal length lens, as well as the pluses and minuses of each focal range. I know this will help a lot of people.
Thanks Richard, 👍 hopefully this in conjunction with your focal length video will help out
Awesome vid. Seasoned reasoning coupled with useful knowledge. Thanks John.
I have a 10-shot limit for panos. Did a double take when I heard 70. :)
Thanks mate. Haha 70 Is excessive and when people do them and move back to a wide angle lens for a 10-20 image pano they don't see much of a difference
John you have easily got some of the best Milky Way photography tutorials out there on RUclips. I love how generous you are in explaining your workflow unlike other RUclipsrs who seem to only tell us a fraction of theirs. Learned a ton from your videos. My favourite astrophotography channel to date, I keep coming back to your channel. A blessing from god. Thank you and keep up with your good work!
I really appreciate that Marco thanks. I'm glad I've been able to help.
I like how you literally have a monopoly on panorama astrophotography.
Cheers mate 👍
Great informative video
As always, great information in a very helpful video. Thanks!
Thanks mate 👍
Amazing information, I really love this channel !!!
Thanks mate 👍
Great break down John! Your videos are very knowledgeable 🙌
Cheers man 👌
Great info on focal length. On my Canon setup, I've found a huge quality difference shooting between RF16mm and RF35mm whereas the RF35 image quality is far superior, but much harder to frame depending on core location. I tend to use shorter focal length lenses tp keep it simple. Thanks for another great video! Stay safe. Mahalo and Aloha.
Cheers mate, yeah the wide focal lengths definitely keep it simple,and that's why they are so popular. I do love a challenge tho
Another Awesome video with some really helpful information! Hoping to get a chance this coming weekend to try out my New 40mm lens
Good luck mate, hope the sky stays clear
Another informative video John, I must admit I seem to be always locked into a 20m Lens for everything. I have only used my 35mm and 50mm a handful of times now I have a tracker it's time I bring the core closer :) Thank you for sharing the pros and cons between wide angle and shorter angle, something to think on next time I'm out.
That's a very normal progression, I did the same thing. Look forward to seeing what you come up with using longer focal lengths 👍
Definite food for thought John, I don't have the problem choosing lenses at the moment as I only have one, a 20mm 1.8! A good breakdown though of what a night under the stars with each focal length entails. Thanks for linking the planning video I'm due a re-watch of that one as when in the field last time out I forgot some of the pointers in that video, i.e. your starting and ending reference stars at both ends of the arch!
And what a good lens that is!
Hey John! A new subscriber here! Thanks for the great info. Do you still shoot with the Sigma 40mm?
Thanks John, Another good video full of the information for tracked panorama enthusiasts. Looking to next dark sky period to give the tracker another outing. 😁😁
That's it mate!! Look forward to seeing what you come up with
Thanks, great information
Your most welcome mate 👍
Thank you so much for your thoughts and infos on this important topic John. Especially the time component made me think for a long time that I'd never decide for a tracker. Now I finally changed my mind and got one and can't wait to try it for the first time. Nevertheless I'll start with a relatively simple setup so that I hopefully won't end up too frustrated after the first night ... :)
That's the go mille, start simple and work up from there.
Great video man👍 you know the idea of compromising and working within your limitations is the age old struggle of every aspect of Astrophotography. My biggest compromising factor is always time. I no longer want to spend the whole night on just one comp😂. With enough time you can do anything as long as you have a tracker. Then there is the correlation of as you spend time in the field creating an image you’re time behind the computer will also go up. Again great video👏🏻
So true, that's why it's so important for everyone to figure out what works for them.
Great Video. I just purchased the Sigma 40mm for my Canon. You said it was big, but it is BIG and HEAVY! I'm looking forward to giving a try this weekend.
Haha yes it certainly is a tank of a lens. Good luck on the weekend
I use wide lenses for full arc, and longer focal lengths for smaller panos.. We get mw for a maximum of 2 hours in southern UK, so my exposures tend to be about 45 secs to one minute, depending on what I want to get done vs time available. Thanks for your input
I often forget how spoilt we are with our skies, but sounds like your making the most of yours.
Thanks for a great video. I'm in the position to make a choice of what lens to get for tracked panorama 🙂 this helps me out in my process 🙏
Glad it helped out mate 👍
Another great video talking about an important topic. I love my sigma 28mm lens and one of the reasons I got it for panos is because 50mm takes such a long time to do panos with and sometimes the weather here can be quite temperamental. I'll often start off too by taking a couple of untracked single shots at 28mm or even 14mm just in case the weather turns bad and clouds ruin my tracked Pano. At least then if that happens the night isn't a total waste and I've got at least one shot to show for my efforts.
One thing I'm still struggling with in terms of panos is stitching errors. I get these weird lines at the joins where the stars on either side of the joins are slightly different sizes or going in different directions. I'm not sure whether this will be fixed by stopping the lens down more or shooting shorter exposures or a bit of both. Or possibly having more consistent 50% overlap in portrait orientation. In the meantime I'm able to kind of fix the problem using the clone stamp tool but it's not easy to get it as good as I'd like.
That's a great idea. I'm sure plenty of people could learn something from that approach. 👍
Thank you for information big bro
Your welcome mate 👍
Thanks! Very timely comment about longer focal length giving you a bigger image of the Milky Way. Richard is hosting Zoom meetings and in the one I was just on he mentioned that very phenomenon. I'll check out his video, though. Now that good weather has finally come to my locale, I want to experiment with panos.
Awesome mate, that worked out well.
Hey John, great videos my friend! Its funny, I have been shooting my panos for the past year here in Southern California using a Tamron 35mm f1.4 lens on my Canon Ra. It has been awesome but I wanted to try my hand @ 50mm so I purchased the Canon RF 50mm f1.2. Unfortunately the image quality is not as good as the Tamron AND (to your point) shooting @ 50mm with the length of time needed to get the full pano was getting crazy! And as you know, if it takes an hour or more the sky moves ALOT! So I felt like it was hard to "catchup" and get the full pano in :-) Anyways, so 2 questions if you don't mind? First, I see that you moved to the Sigma 40mm, given my situation it feels like to right more for myself as well as it will give me a bit more resolution compared to the 35mm as well as possibly reducing the imaging time since right now I do stop my Tamron down to f2 but I should be able to comfortably shoot the Sigma @ f1.8 (or even f1.4)? How did your rig deal with the added weight though of this lens? I hear that it is really big and heavy! Lastly, when shooting your panos do you start with the horizon and work your way up or do you start at the top on the arch and work you way down? Anyways, thanks again for your video's and insight!!! Looking forward to more of your work and teachings!! Thanks again!
The sigma 40 for me replaced my 35 and 50 which was great, and it performs awesome wide open which cuts down on exposure times, it is a hefty lens for sure but with my star adventurer it works flawlessly, I think the smaller trackers would struggle tho. I think having a 28mm and the 40mm is a perfect lens combo for panoramas and both are incredible quality
Hi John, interesting video. In my opinion, 14mm is best if you only have a few mins to take a panorama ( or a single shot), having driven 4 hours to the site, and having to drive 4 hours home=8 hours driving altogether! 20mm or 24mm F1.4 Samyang lens (maybe stop to F2.0 or F2.8) if you have 30 to 60mins. For smaller detailed views (we are entering telescope astrophotography), 35 to 50mm could be used, but I don't think you can do 4 rows of horizontal panoramas for 720 degree panorama! at 50mm. But could someone work on 2 rows, and someone else work on the other 2 rows at the same time with same equipment to halve the time?
Everyone will have a focal length that is optimal for them, very interesting concept with 2 cameras, I've never tried it but can't see why it wouldn't work.
P. S, I prefer field time to post processing time, lol
Alot of people would agree 👍
