Not an easy object for a OSC camera however, it will be interesting to see how the 2600MC fairs Steve

Agreed, there are almost no photos on Astrobin taken of this object with an OSC.  This was part of the reason I wanted to give it a go.  However, if you - or other syndicate members - think it beyond the capabilities of the scope or site, I am happy to drop this request.   Brian

Brian the fact the scope is F2.8 will make up for other short comings, personally I would do a quick 5 hours on one pane and see what you get. If the data is good or shows promise then shoot At the very worst you get to scratch an itch! steve

Hi Steve,  It may well both worth a try, but I don't see a lot of support from my fellow syndicate members.  Since I don't want to take up quality time on what might be a bit of a guess (particularly at a time when there are a number of other good targets up), I will withdraw the suggestion.   I will, however, start another thread with another suggestion.  Thanks Brian

Brian 5 hours is not so much of a loss in my opinion but hey ho the choice is yours as they say Personally, I think it will do a pretty good job if I am honest As for the other member I think Vikas is away shooting time lapse and the others seem none to vocal about objects so shoot away and keep the pier busy This is a pretty new syndicate but I do hope as it grows we get more active member like P14 P1 Steve

Steve,  OK I will put onto the queue with 100 x 180sec on the Northern part of the mosaic and let's see how it works out.  CS Brian

Brian  I can leave as is with 180s subs but personally I would suggest 300s ? the camera is 16bit so will cope well with any bright whilst getting on with collecting the dim stuff   steve

Hi Steve, Thanks for the suggestion. Lets do 60 x 300secs then.  It will be interesting to see what we get. Brian

Hi Brian, I also need to get a little more active on the forum. But a big disadvantage of astrophotography is that the image process takes a lot of time. But as far as your proposal is concerned, I completely agree with you. let's indeed try what yields 60 x 300 s. If it is very promising then we also take the southern part of this very beautiful object in the northern sky and if necessary we do another 60 x 300s per panel. Sh2-240 is the little version of the Gum nebula. Greetings,Mike

Hi Mike, All good - thanks for your support.  Brian

Hi, I have just reviewed the data for Sh2-204.  Although it was taken during dark of moon, the star counts vary by a factor of 3 over the subs.  Only 20/130 subs have a pretty steady star count of 15000, but the rest have a mean of around 8000.  In effect, we have collected around (20 + 110/2 ) x 180 sec of data or 3.5hours.  I attach a quick reduction.  Its not very impressive and, even if the weather had been goo, I don't think it would have been significantly better.   Consequently, I propose NOT to go ahead with the other part of the mosaic.  A useful lesson, for me at least, on the limitations of this rig and the site.  Brian
