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.
