don4l Posted November 8, 2020 Share Posted November 8, 2020 This is an often overlooked nebula just East of the North American and Pelican. It is quite a bit fainter, but also absolutely plastered with stars, which overwhelms the nebula itself. I've been playing with Starnet++, and this is the result. The stars were imaged last night in dreadful conditions. I've been experimenting with shorter exposures for stars, and these were 30s subs for the R and G, and 60s subs for the blue. (my camera is not very sensitive to blue). Next time, I will try 15s for R and G, and 30s for blue.This is 40m Ha, 110m OIII,, and 4.5, 5.5, 18m R, G, B. Total 178 minutes.This shows where it is:-C and C welcome. 4 Quote Link to comment Share on other sites More sharing options...

don4l Posted November 9, 2020 Author Share Posted November 9, 2020 Posted by: @MarkAR That's a superb image Don, not seen that nebula done before.I think that there are loads of targets that get overlooked in Cygnus. Probably because there are so many bright well known ones in the vicinity. 1 Quote Link to comment Share on other sites More sharing options...
MarkAR Posted November 9, 2020 Share Posted November 9, 2020 True, think it might be a bit big for my scope. So either wider field scope or mosaic and headaches ? Quote Link to comment Share on other sites More sharing options...
Dmack1 Posted November 9, 2020 Share Posted November 9, 2020 Thats really nice. Not one I knew about either so another addition to the long list of targets! Quote Link to comment Share on other sites More sharing options...
Gina Posted November 9, 2020 Share Posted November 9, 2020 Very nice Don ? Good to see less popular nebulae imaged. Yes, Cygnus is very rich. Quote Link to comment Share on other sites More sharing options...

Carastro Posted November 15, 2020 Share Posted November 15, 2020 That's come out very well Don, and if the stars are as you say you have done a very good job of controlling them.I just put this target on my list only a few days ago, and was going to try to grab it before it disappears. Not sure how faint it is, I am guessing its middling, not too bright and not too faint.Was planning narrowband so HORGB sounds a good mix.Carole Quote Link to comment Share on other sites More sharing options...

It is much dimmer than the North American, but much brighter than SH2-114. There is a good bit of SII in it as well. In fact, the SII seems stronger than the OIII.Here is my first attempt, taken in 2018 with my Astronomik "Halo Special" Ha filter This is Ha, G, B. I don't think that I did much to reduce the stars in this version. 1 Quote Link to comment Share on other sites More sharing options...
