ultranova Posted September 27, 2020 Share Posted September 27, 2020 That's come out quite well, the color of the target in general is ok, but for some reason the edges going vertical seem over white on both sides what what it seems like on my monitor, almost like over done flats. probably not the case. well done Paul Link to comment Share on other sites More sharing options...
Graham Darke Posted September 27, 2020 Author Share Posted September 27, 2020 These are just light frames only. You are most likely right, it needs flats to correct the edges. Link to comment Share on other sites More sharing options...

Graham Darke Posted September 28, 2020 Author Share Posted September 28, 2020 Reprocessed, less aggressively. Seems to have reduced the issue down the sides. 6 Link to comment Share on other sites More sharing options...

Lee_P Posted September 28, 2020 Share Posted September 28, 2020 Great picture! I'd be interested to hear your thoughts on the L-eXtreme filter, I'm considering getting one myself. Link to comment Share on other sites More sharing options...

It’s not cheap but for use with a colour camera I think it’s the best out there presently for emission nebulae. 1 Link to comment Share on other sites More sharing options...

I'm in a city centre and previously used mono + filters which were great, but really I'm after a simpler workflow. I'm hoping that the L-eXtreme could be the answer.

Graham Darke Posted September 29, 2020 Author Share Posted September 29, 2020 This shot was taken from my caravan in Cumbria where it’s Bortle 3 but I live a Bortle 8/9 Tyne & Wear. Here’s a shot from home with it. The Witch’s Broom. 1 Link to comment Share on other sites More sharing options...

gorann Posted September 30, 2020 Share Posted September 30, 2020 Great image Graham, especially version 2! I am extra pleased to see this image since I bought the same flatfield quadruplet Apo (TS 71SDQ) from TS in February to use as a travel scope. Then, no travel happened, and we all know why, and I have not really got around to test it properly. It is made by Sharpstar and for some reason TS have stopped selling the scope which made me slightly worried. But your image suggest that the flat field works and you have nice round stars in all the corners, at least in your exemplar. I assume you are totally happy with it? 1 Link to comment Share on other sites More sharing options...

I used to have the 65q but sold it and instantly regretted it afterwards. I love having a flat field with no messing around with flattener spacing. It’s super portable and goes with me to my caravan whenever I can. 1 Link to comment Share on other sites More sharing options...
