Ken, No this it without the filter. I did take a batch of 60s on M31 with the LP filter which is in line for stacking after the re stack of the wide field image. Result will be posted. This will tell me if I wasted over £100 Mind you it could be good with the modded camera soon to be back in action. Cheers Nige.

Steve, this image has been wiped gradient and vignetting, isolated with a mask, less-more with a mask and isolate again to remove a very bad top left gradient

I agree a new thread to discuss this is a good idea. So, last night I had a battle with my imaging PC, It shut down on its own 3 times while gathering subs, 3 hours spent getting 1 hour of 30s on Horsehead, flame & Orion with my 135mm lens. then the fog rolled in. DSS refused a few subs. I took darks flats and added the stock bias. I had a very hard time removing gradients so i'm re stacking without the flats to see if that helps. The info is there, removing the gradients has taken so much detail out though. Canon 1300D 135mm lens, 94x30s light ISO 1600, 40 flat, 50 dark, 50 bias. Star Discovery Alt-Az mount, DSS & StarTools. Cheers Nige.

I have asked admin to take a look at the last couple of pages of this thread to see the discussions about a new topic. Nige.

I didn't realise that the post was private. I wonder why. here's the posts from me and the reply from admin. Hello Admin. There is a thread in getting started with imaging called the No Eq DSO challenge, we have a lot of very useful information which is difficult to find when you want to refer back with 60 pages and almost 1500 posts. Quite a few people post their info and images now, also someone pointed out that he also refers to the thread for info as its very similar to non guided EQ imaging. Would it be possible to have a new topic in Imaging called, " Alt-AZ and low budget " or something along those lines ? A new topic would be very useful to organise the almost lost good information. I think a fair few would agree that we could do with a new topic as our imaging information is quite different from guided EQ imaging. Best regards Nige. Reply You can of course start a new thread yourself. My reply. Thanks for your reply Peter, The trouble with a thread is as we have found with the No EQ thread it becomes to big, to look back on past info it can take hours sifting through many pages of posts. With a topic specifically for what we do it can be split into threads for easy reference. I guess the answer is to have a few threads running, to cover the problems we face, shared information and showcase. Regards Nigel. The reply came from Cornelius Varley (staff) Perhaps a PM to site administrator might do it. I emailed admin too, in fact I emailed admin because nobody replied to the post. I pasted the same question in the email and had no reply by email , just this short reply here. I think if more ask and quote this discussion it might get admin to consider a new topic. I'm not entirely happy with the short un interested reply I got, and will push some more, another email or PM. I'll think about it today while I attempt processing last night's data. Cheers Nige.

Steve, the only answer I got is on the post asking for the new topic. If it was backed up by others maybe they might consider it, maybe admin think it's not suitable? I personally can't see an reasons why not. There are 61 following this post and quite a few using it for information on not only Alt-Az imaging but short exposure imaging. Having multiple posts amongst several hundred other posts in the imaging topic trying to cover our topic would be worse than the one post. A topic in imaging section would keep good information organised for present, new and future user's without getting lost in thousands of posts I'm a little disappointed to be honest, but we can only try. On a lighter note, the sky's are clear here, hopefully they will stay clear for a few hours, I'm going to attempt Orion with the horse head with the 210mm lens. Extra hour to recover tomorrow Cheers Nige

Well said Steve. Unfortunately admin do not seem that interested suggesting start a new thread. Maybe I didn't explain in enough detail to get the point across. Hmm Nige.
