What is it?

[adamsp123]

I was playing around with my "upgraded" Atlux mount with Nexatlux controller to see how far I could get with the guiding accuracy etc.

So what is this object? I was after the bubble nebula NGC7635 but missed it a wee bit it seems, can anyone identify the object please.

Details of shot - 4X15mins each of LRGB 1xbin Atik383L+ @ -20C on 190MN guided with 50mm finderscope, QHY5v and PHD.

Quickly tweaked in PS.... uncropped.

I know I have a terrible gradient to sort out but any critique of the shot welcome, I think the guiding isn't too bad.

Thanks for looking

What field of view does the picture cover?

He's good, isn't he?! Quick as a flash...

I wouldn't have known it from Adam but it looks like a tasty object for the list.

Cheers for that, looks an interesting object for a bit more work.

Just for the fun of it, the following is a test image I took of this object to check for differential flexure on the 16th July. This is just two subframes (all I needed to check for image shift) but it's certainly an object I'd like to re-visit.

And here's the Ha version

That's a really nice little shot
