Is astrophotography real? Is that even the right question? Maybe it's better to break things down a bit and answer smaller questions... like are colors real? This is the second part in a series about whether astrophotography is real. We get into Whorfian ideas of cognition, optical illusions, neuroscience and more!

Lets measure the SNR! How much better is a a dark site than the city?

$Why Your Stars Arent Round (And How to Actually Fix It) Ever look at your stars and think, why dont these look like circles? In this video, I break down the most common telescope aberrations — what causes them, how to tell them apart, and how to actually fix them (or figure out when you cant). Kstars Aberration Inspector Tutorial: https://www.youtube.com/watch?v=IbbxJJS9W48&t=380s @johneevans1 0:00 – Intro: Whats actually wrong with these stars? 0:40 – Welcome / My Sharpstar 130 1:13 – Definitions (on-axis, off-axis, image circle, diffraction) 2:44 – Why stars arent round (the eye analogy) 4:07 – Spherical Aberration 7:02 – Field Curvature 9:48 – Coma 11:45 – Astigmatism 13:21 – Pinched Optics 13:59 – Honorable Mentions: Miscollimation, Tilt, Chromatic Aberration 15:14 – Three Kinds of Problems (Optical vs. Mechanical vs. Seeing) 16:09 – Why Combined Aberrations Are So Hard to Diagnose 17:01 – How to Actually Fix It (Order Matters) 22:02 – Newtonian Reflectors 22:23 – Schmidt-Cassegrains (SCT) 22:58 – Classical Cassegrains 23:11 – Ritchey-Chrétien (RC) 23:32 – Maksutov-Cassegrain 23:49 – Dall-Kirkham 24:05 – Refractors (Doublets/Triplets/Quadruplets) 24:37 – Outro and Thank You Become a buymeacoffee member to help choose which products I review: https://www.buymeacoffee.com/deepskydetail Affiliate Links: High Point Scientific: https://www.highpointscientific.com/?rfsn=8751569.cc9d94 Agena Astro: https://agenaastro.com/?rfsn=7802039.3f4caf Skywatcher HEQ5 Mount https://amzn.to/3NVrVQi Skywatcher 80mm F7.5 Doublet https://amzn.to/47mbfZi ZWO EFW mini filter wheel https://amzn.to/48OxhoN Optolong LRGB Filter Set (1.25) https://amzn.to/47r23Tw Orion 0.8x Reducer https://amzn.to/47s64a4 USB RJ45 Cable for Controlling Mount https://amzn.to/4aPlIzu Raspberry Pi to control mount https://amzn.to/48mTBWH R Pi case with touch screen https://amzn.to/3HvdNKl ZWO Autofocuser https://amzn.to/3Skg0hX ZWO 294MM Pro Camera: https://bit.ly/3tZmjOo HEQ5 Mount: https://bit.ly/3O7VQVz (mine is Orion Sirius, which is equivalent) ZWO Filter Wheel: https://bit.ly/3Soo5lw Optolong Filters (LRGB, SII, Ha, OIII): https://bit.ly/3SlEPtJ (the Ha and OIII narrowband filters are better than what I have) Skywatcher Evostar 80mm: https://bit.ly/4bfVjev (equivalent lens) USB RJ45 Cable: https://bit.ly/48FRj50 (connects mount to laptop directly; mine is a different brand, but this should do) ZWO Autofocuser: https://bit.ly/425XUDB 0.8x Reducer: https://bit.ly/3tQlbg7 (mine is Orion, but this should be equivalent) Join this channel to get access to perks: https://www.youtube.com/channel/UCoI4bUAKNI3rdvesiNqtYJw/join$

I made a neural network to sharpen astro images!

Are longer subs really better? An experiment in broadband and light pollution.

That doesnt make sense, does it? The complex relationship between SNR and integration. Part II.
