Avalon Linear Fast Reverse / Takahashi FSQ85 0.73x / Atik 460EXM with 3nm Ha and 3nm OIII.
This is a bi colour image of NGC6888. The field of view enabled me to also capture PN G75.5+1.7 (Soap Bubble nebula). There’s also some OIII clouding around the bright star 34Cyg that I have never come across in similar captures before. I was pleased that the Soap bubble was so obvious as I often find I have to hunt for it in images. It’s good to be able to show just where it is for those who have heard of it but have been unable to see it. This is a total of 24×30 minute exposures.
