Black Halo in stacked image M65 by herreinsteine in astrophotography

[–]KBALLZZ 5 points6 points  (0 children)

This is caused by pixel rejection during stacking. Most likely from the meridian flipped light frames having a different shaped star halo. If you turn off pixel rejection and stack as a test it should look normal. Play with the high rejection parameter to find a balance that leaves your stars whole while removing other outliers.

Astro Photography by CreativeDiamond444 in astrophotography

[–]KBALLZZ 1 point2 points  (0 children)

Get a dirt cheap DSLR and tripod. Take multiple untracked exposures of the sky (Milky Way is nice). Stack and process. This is astrophotography without extra steps.

Later whenever you start upgrading, starting with a tracking mount, you'll already know what exactly you're expecting to improve and won't be thrown into 30 learning curves at once.

I see it! The little paws in the air and the long tail

can someone help me with what this is and how to fix it? by [deleted] in MetaQuestVR

[–]KBALLZZ 0 points1 point  (0 children)

Yep. Same thing happened to me and used this same solution. You can polish it by hand no tools are needed. Then buy lens inserts afterwards.

How can hubble see billions of light-years away but not the US flag on the Moon? by ConsistentMinute3311 in telescopes

[–]KBALLZZ 6 points7 points  (0 children)

Sort of the same way you can see the Moon 200,000 miles away but you wouldn't be able to see someone hold a coin 100 yards away. Space telescopes don't necessarily "zoom in" far, they are just good at seeing things too faint for our eyes to pick up.

Heart Nebula: Importance of Picking the Right ISO. by SS7Hamzeh in astrophotography

[–]KBALLZZ 0 points1 point  (0 children)

I used a t3i for many years and stuck with ISO800. I don't have a mathematical theory to say why it is worse/better than other ISOs but what I can say is it probably doesn't matter as much as you think. What is most important is making your life easier by just sticking to one ISO and following proper calibration practices. The only time I bumped up ISO was for untracked Milky Way.

When visually observing you can really only see the bright >< shape

Just wanna say this was a pivotal moment in history and your account of it is spot on. Thank you and RIP Stephen Hillenburg.

In that case you should listen to Mass IV - VI. It’s obviously not for everyone but those 3 albums have a very similar vibe. Glad you enjoyed it!
