This was painful to process. I think I got decent details in the nebula itself (considering that I used non modded dslr) but the surrounding interstellar dust really did dissapoint me. Should I collect more light to get better details (like 14 hours instead of 7)? Should I try increasing individual exposures to 3 minutes from 2? Should I switch to more optimal target for my setup? lol
<br>P.S. With the help of higher powers I somehow managed to accidentally get single 7 min exposure (at 300mm) without any guiding. Magic. For comparison usually for 2-3 min frames at 300mm I have 25-50% of failures which I just delete.

Нужен просто хороший рефлектор хотя бы 150 mm. Ну и конечно астрокамера, ZWO например. Ясного неба!
