NGC7635

[Ant]

Despite the near full moon, I had another bash at the bubble.

Made a couple of school boy errors (again), forgot to polar align - so I have clear field rotation between frames. The sky was quite bright, to start with from the twilight and then from the moon.

I used the Baadar Moon/Sky Glow filter. Imaged through the 6" F5 newt and guided with the ED80/DMK combo.

20 x 2 minutes and 26 x 5 minutes. With the moon I think that 5 minutes may have been a little high.

I could do with some flat frames, as i think this would help my gradient issues. I removed some of the gradient then continued to process, I know that there is more nebula around the bubble that you first think so I decided not to continue any further, but it still needs help.

Going to get myself a NB filter (Ha 7nm) at the end of the month.

Cheers

Impressive Ant. What are the scratch type marks at the top of the photo.

Cheers Mick, I think they are hot pixels.

Maybe I need to do darks as well. But I think I can live with them.

had another little play...

[Doc]

Thanks for the info Ant. That second one really adds punch to the bubble.

Hi Ant'Nice image of the bubble neb.Mark

Nice one Ant!

If you choose Sigma combine method you will lose the hot pixel problem.

As you have so many subs , it will give a better combined result

Hi Arran cheers for the tip...

I'll give that a go.

Still at it Ant

Come back to this one when you get the Ha filter, and take as long a sub as you can. All of that stuff that appears to be noise will spring out at you with detail and texture, and there'll be no trace of gradients with it.

The flats will help you though, definetly worth going for those, with bias and darks too.

Nice image mate.

That SE camera really seems to agree with you.

I can see improvement with every image taken since you bought it...

Keep it up...

Looks good Ant, plenty of detail coming through. I must say I do prefer the first one though, much more natural looking to me. But heck, it could be just my monitor.
