Hi all,

I've just handed in my homework - M33 - rather late. I think I've missed the end-of-term deadline! Overall I'm fairly pleased with how the image has come out, but I'm disappointed that the stars aren't sharper. I got the focus absolutely spot-on (if my Bahtinov mask is telling the truth!).

I haven't learned how best to sharpen stars in processing. I was wondering whether anybody else has experience of doing that, and if so, what methods they have found to be good. Does anybody have any thoughts or advice they would be willing to share?

To quote Noddy Holder - "Merry Christmas Everybody!", and I look forward to more group chats etc with you all in the New Year.

Hi Jonathan,

I added my picture into the group's collection, thinking that would do the job, but that did leave things a bit unclear I guess. Apologies for causing confusion! Here's a link which should take you to it - https://astrob.in/9d5zcy/0/. If for any reason that doesn't work (I'm still learning how to do things in AstroBin) I think you can probably search on my name and/or on M33 and hopefully find it that way. Or find it by looking at the group's pictures and sorting on date, where it will be the newest one, or one of the newer ones.

Hope that helps!

All the best.

Any target and acquisition suggestions for areas with poor seeing?

Hi, all. I was hoping to pick folks brains about ideas for targets and perhaps acquisition techniques for areas with routinely poor seeing. For context, I live in the San Francisco Bay Area on the SF peninsula. My place of residence and where I do 90...

Please share your thoughts about when the flats should be taken during a session.

I am looking at all the information and different opinions available on the internet on whether flats should be taken after the subs, or that it is ok to take them at the beginning. There seems to be a consensus that it is absolutely imperative to ta...
