Photo club Zoom meeting
During today's Zoom we discussed Astrophotography, where is infinity on your lens, Hyperfocal, photopills among other items.
Why isn't the infinity stop really infinity? because for autofocus to work the detection needs to hunt for the focus point.. Therefor a lens must travel further than "infinity" and then return a little to find the focus.
Potopills can help determining the hypeerfocal distance. Also the guide ot 1/3 into the image is usually good.
This looooong, 2hr, video may be of interest to a few. https://www.youtube.com/watch?v=iuMZG-SyDCU
Table of Contents: 00:00 Intro, 04:43 Gear, 15:23 Prep, 36:43 Calibration, 46:53 Capture, 01:02:36 Deep Sky Stacker, 01:14:13 Photoshop
Additionally; Usually you are given the 500 rule but it is a GUIDE not a rule. It's a good starting point but you need to take some test shots and make adjustments. More information https://astrobackyard.com/the-500-rule/

I can't get a new mirrorless camera
Why not? I've invested in glass and newer cameras have different mount ...
Look as your "investment" as a sunk cost. I and perhaps you, enjoy photography as a hobby not as a money making craft. So don't use the excuse that you have an investment to justify not enjoying your hobby.
You can't take it with you. Your children won't want your full frame or aps-c camera or your f/4.0 600mm lens. They'll sell it for pennies.
Just do it!!!;
One of the advantages if mirrorless is better optics design view here. If you're going to mirrorless get me glass.
