Thanks swill look there I will have a look thank you.

Hi, I am struggeling to find the right place for this so if it is in the wrong place feel free to move to the right thread. Know to the question. I have fitted a M 48 thread to my scope tube whitch i use to attache a FF with a M 48 thread. To save keep taking all the bits off my scope Im looking for end caps the fit both items ( 1 female and 1 male ) I have looked all over the net and the only thing I can find is DLSR covers for camer bodys at rediculous prices. Can anybody point me in the right direction to get some? Thanks and stay safe Simmo

V nice m8. Long time no see.

Sorry vlaiv, cant seem to get the fits to upload, PNG and jpeg works fine.

yep, I tried to upload the fits but i keep getting an error, i will keep trying. I think the net is heavy with traffic.

I know it has problems and its the wrong scope for the job but clear sky is clear sky! Vlaiv is looking into the poor backgrond problem, not sure if its a flat problem or internal relections but it is what it is. Taken with ASI 1600mm through SW 72 ed ( wrong scope for the job ) about 5hrs RGB over 4 nights. Hints tips and problem solving welcome. Thanks for looking

Flat dark sub Master dark Single flat sub Single light sub Hope they are ok, had to play around a little with them to load.

Yep will do that in a bit.

Hi Anthony, not sure if i have solved the problem but looks better. It was all guess work Im afraid so no cunning plan to tell.

Hi vlaiv. Well i tried last night with my best guess and it did come out a little better, Still not 100% right but I think Im heading in the right direction. It didnt help that my framing was way out with my other subs but at least I feel im getting somewhere. I still wonder aslo about internal reflections but not sure how to best sort that. If you look close you can still see the swirls but not half as bad as what it was.

WEll ill give that a try tonite and see what I get. The only thing Im not to sure of is the actule sub length to us for the flats. I have read all the thearoy stuff on flats and I have to say a lot of it is over my head but will give it a try.

Hi Vlaiv, I have done something like you sugest. The rgb subs where taken on seperate nights and the patern is the same for all 3 sets of subs. The only improvment i got was on the third night doing green when I increased the ADU of the flats in APT from 20000 to 25000. The patturn was still there but less prononced. Thats why im wondering if its a flats problem. Im using a gain of 76 on my ASI 1600mm for the subs whitch is new for me as I have been using 200 for narrow band would that have any bearing?

Hi all. Not sure where Im supposed to post this one so If im in the wrong place I sorry. Now to the problem: As it gallaxy season ( not my fav time of year ) I thought I would give the Leo trip ago using my SW 72 ed. I know is not the scope for this target but I was just playing and trying to get my head around RGB imaging. I have had some good results with my set up in narrow band but RGB is giving me real problems. Im not sure wheather its my flats or internal reflections or just to long subs but im getting greenish swiirls in my images on all 3 filters ( less so on the green ). I can remove some of it with masks and ABE / DBE in pixinsight but there is still a stubborn section that is always there. Here is the rgb image after combination and a stretch; Im happy with the targits but the bacground is driving me up the wall. Any ideas on whats wrong or how I can get rid of the haze? Thanks i advance. Simmo

Nice one Geof. Looks great as is to me.

Thanks I will give it ago.

Thank you Bryan.

You are very kind, thank you.

Thanks Gina.

Thanks Mark, yes there will but when? lol the weather has been so poor this year.

Thank you, that look better, Did you use the mask script in PI?

V nice.

Thank you, I find it hard sometimes to not over stretch things.

Why is this game so hard! 2 storms, rain, wind, tech problems and more rain and wind! This was meant to be a quick one but ended up a real long job. Ha data was v good but the Oiii and Sii was very poor. I would not have used half the data if I could get chance to redo it but as it was I wasnt going to waste what I had. 60 x 240 Ha 58 x 240 Oii 49 x Sii all taken with Zwo 1600 mm through SW 72ed I always seem to have problems with not seeing green so i tried to get brid of as much as i could see. Any hints and tips most welcome and thanks for looking.

V nice, I must try and get one of these lenses, getting past the wife is a problem though!

Still a nice shot!
