Hi all, Here is one other image I'm working on Melotte-15 IC1805 in the Constellation of Cassiopeia 2nd of September through a William Optics FLT-110 Triplet APO refractor Atik 16Hr cdd camera. Guided with a Celestron 80ED And Sac 4.2 CCD camera with PhD guiding software On a CGE mount. Processed in Images Plus V3.5 and Photoshop CS2 exposures where 25 x 5 Min in H alpha. I must say I find this type of astrophotography fascinating planetary nebula not one is the same and the detail when the image appears on the screen on the first exposure is great. http://webtreatz.com/component/option,com_zoom/Itemid,27/page,view/catid,10/PageNo,9/key,74/hit,1/Carl.

Really nice image - I'm sure you're well chuffed. 30 X 5 Min subs 150 Min exposure in H Alpha.
Ummm, don't want to upset the party by interference from a back seat driver, but if you had the sort of sky I had last night I would have thought that it would have been a good night to take images other than narrow band Ha - the point being that narrow band Ha imaging can be done in bright moonlight. Here, last night was unusually transparent, so there would have been less interference than usual with broadband B & G images - just what you need for "true" colour imaging. Hi Brian, The skies last night where great And I did get the Green & Blue colour for a different image I'm doing also. The other imaging I'm doing is Melotte-15 IC1805 in the Constellation of Cassiopeia hoping to post this image here soon in full colour. Hope this answers your question. Carl

Hi All, Hope you are all keeping well. Here is an image I started last night NGC 7635 The Bubble Nebula through a William Optics FLT-110 Triplet APO refractor Atik 16Hr cdd camera. Guided with a Celestron 80ED And Sac 4.2 CCD camera with PhD guiding software On a CGE mount. Processed in Images Plus V3.5 and Photoshop CS2 exposures where 30 X 5 Min subs 150 Min exposure in H Alpha. I must say I'm Very happy with 110mm FLT. Lets hope we get some more clear nights so I can get some colour for this image. http://webtreatz.com/component/option,com_zoom/Itemid,27/page,view/catid,10/PageNo,9/key,73/hit,1/

Thanks for all your comments lads. I'm looking forward to the dark nights and giving this scope a hard nights work. I also forgot to say thanks to Dave Grennan for helping me to process this image

Hi All, Here is an image taken over a couple months because of the weather M57 The Ring Nebula is a very difficult nebula to process next time I will pick something a little bit easer. Image taken on July & August through a William Optics FLT-110 Triplet APO refractor Atik 16Hr cdd camera. Guided with a Celestron 80ED And Sac 4.2 CCD camera with PhD guiding software On a CGE mount. Processed in Images Plus V3.5 and Photoshop CS2 exposures where L+HA (RGB) 60:60:60:60 http://webtreatz.com/component/option,com_zoom/Itemid,27/page,view/catid,10/PageNo,9/key,72/hit,1/Carl
