Guest ollypenrice Posted September 7, 2013 Share Posted September 7, 2013 When I came to process this I had a surprize because I thought the dust lane associated with VdB152 was quite short. It isn't, as you can see! Had I known I would have rotated the cameras to see where it led. To its left is a PN only discovered in 1980, which seems remarkable. It will be worth a good Ha dose at some time to try to pull out the strand of signal glimmering in a line from the reflection nebula, and some O111 would help the PN. All in all a more interesting bit of sky than I was expecting.

+Graham Posted September 7, 2013 Share Posted September 7, 2013 That is a remarkable picture there Olly. I am assuming the single thin red line is the shock wave from the pn. I take it you will be going back to this with rotated cameras and all filters. Love to see that when its done. Link to comment Share on other sites More sharing options...
Guest ollypenrice Posted September 7, 2013 Share Posted September 7, 2013 I'm not sure whether or not the Ha emission is associated with the PN. It's possible but could it be a tidal effect creating a shock front? I will certainly try for some Ha. Olly Link to comment Share on other sites More sharing options...
+Graham Posted September 7, 2013 Share Posted September 7, 2013 Look forward to that with great interest Olly. Link to comment Share on other sites More sharing options...

+Graham Posted September 7, 2013 Share Posted September 7, 2013 Olly what do you use to focus your scopes. I have looked at the hi res picture and the focus is perfect right down to the smallest stars. If I could get mine to within half of that I would be well pleased.

+Graham Posted September 7, 2013 Share Posted September 7, 2013 Also whilst studding the hi res picture I noticed that the thin red wave is curving away from the bottom left corner in a near perfect arc. Could you have found the remnants of a sn ?? Link to comment Share on other sites More sharing options...
