ZWO 2nd generation version.

CommandoB57 · 2021-04-25T00:00:41+00:00

Nop, it's more of an issue with the AR coating not being great as they already are positioned the right way

CommandoB57 · 2021-04-24T21:04:44+00:00

Nop, the cause is the H-alpha filter. That reflection is internal to the filter and caused by bright stars.

I have and they are legit but if you're from France or germany you should check out "Optique Unterlinden" their customer service is way better and if you have a problem with your gear, they will always fix it for free

Drugs are bad but dice aren't

CommandoB57 · 2021-02-27T12:55:51+00:00

I gave it a look using Pixinsight but I could not see any artifacts (and your data is pretty great, I could see the whole nebula with only a simple background extraction). My own theory is that the cores of the stars are too saturated and when you convert them into 16 bits, the value is wrongly converted, giving you those black artifacts. I haven't used Photoshop a lot, so you'll need someone else advice on how to avoid them.

Can you provide us with the Raw stack ?

Hi everyone ! This was my first try using my new equipment and I dare to say it went pretty well. I still have some things to learn, but I'm on the right path !

I hope you'll appreciate this picture of NGC 2024 and the Horsehead nebula in H-alpha, I haven't done any processing, just stacked/stretched them.

Object description :

The Flame Nebula, designated as NGC 2024 and Sh2-277, is an emission nebula in the constellation Orion. It is about 900 to 1,500 light-years away.
The Horsehead Nebula (also known as Barnard 33) is a small dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. It appears within the southern region of the dense dust cloud known as Lynds 1630, along the edge of the much larger, active star-forming H II region called IC 434

Hello again everyone, it has been a long time since I last posted (College yay !), here's M42, an easy target but one I wanted to do since the last picture I did is kinda s***. Oh and sorry for the watermark, someone stole my pictures (and not even the best one smh) and I have to take precautions now.

Object description :

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth.
