Re: M31 Andromeda and NGC7635 Bubble Nebula

Hi Dariusz - nice job! You've brought out more colour than I could and the background is definitely better. I'd like to know how you did that. The galaxy itself shows more detail. Did you restack my 30 subs, darks, bias etc in Deep Sky Stacker or did you use my stacked file?
Cheers
JB

Re: M31 Andromeda and NGC7635 Bubble Nebula

Thanks Dariusz. It will be interesting to see your result. For the 700d the stacked image is 106mb. (For the 450d they're about 70mb). If you have a gmail address you can access my google drive. I'll place the stacked image there and pm you.
Best

Re: M31 Andromeda and NGC7635 Bubble Nebula

Hi Dariusz - interested in your comments re colour channels. My colour perception is not very good - something my wife points out frequently! I've watched youtube videos showing astro photo processing (Deep Sky Stacker and PS) but I've always thought they would likely be starting out with a better i...

Re: M31 Andromeda and NGC7635 Bubble Nebula

Hi Dariusz and thanks for your input. NGC7635 is a crop, the central portion of the stacked frame. Like you I had some issues with the edges and corners despite the fact that I have a .8 reducer/field flattener in the way. M31 I'd agree with you about the processing. It's difficult to know when to &...

Re: M31 Andromeda and NGC7635 Bubble Nebula

Thanks Chris. It's very much a work in progress. I'd love to get velvety black backgrounds and more colour! Still progress is being made!

M31 Andromeda and NGC7635 Bubble Nebula

Bubble nebula 210917 equalised low curve sat 17.jpg M31b.jpg Hi folks, I've been using a Baader modded 450D for the last couple of years but recently had my 700D similarly modded and these 2 images represent my first nights out with this camera. The telescope is an f/7 102 triplet apo refractor wit...

Virtual Moon Atlas software

Hi everyone. Dark nights coming in! I attended the opening meeting of the club's 2017/18 season last night. During the meeting Pete and Paul made reference to an atlas of the moon you could use to identify lunar features and aid observation. While many will already be aware of such software I though...

Re: Stepper motor upgrade for LX200

Update
I've ended up with a Revelation Superfocus R and P with an add on stepper motor which should be controllable from the MHP.

Stepper motor upgrade for LX200

Hi folks, Sorry I haven't been able to get along to recent meetings and I certainly haven't been able to spend as much time as I should on this hobby! I wondered if anyone could advise on how to motorise focus on 10" Classic so that I know what the focus position is and can return it accurately...
