Hello,

 

The last week I've been busy capturing some object high above and far away.

In this image you see M31.

 

I used my Canon EOS 6D mark ii. With a Samyang (US: Rokinon) 135mm @ f2.8. Iso800

 

80 frames of 90 seconds.
20 bias, darks and flats.

Mount: SkyWatcher Star Adventurer.

I focused with a bahtinovmask and Backyard Eos.

 

But I have a question regarding flats: When I open the master flat created with Deepsky Stacker it is black. Only when I increase the brightness to a maximum I can see some vignetting. I thought flats would be greenish or yellow/White?

I'm completely new to the whole Darks, Flats, Bias way of doing things, but with results like that, I wouldn't worry too much about it. Beautiful image!

Thanks for your reply.

 

It seems to work.

 

When I saw the first lighs on my display I was like:  'Well, thats not huge...' but after editing it went even better. ;)
