Description

Moon is up and I had two clear nights (with a rainy day in between) so I have been shooting Ha with my Esprit 150 and ASI1600MMpro (on Mesu 200). This was the first try of the TS 3" 0.79x reducer/flattner on the Esprit 150 and I am pleased how well the reducer worked, at least for the ASI1600 image chip. So here is a two panel mosaic finished off last night. 18 x 15 min on the right side and 20 x 15 min on the left side, with a large overlap in the centre to give more data to the details there (all at gain 139, offset 50 and -20°C).

The nebulosity surrounding Sadr (gamma cygni - the central star in Cygnus and the big one to the right in the image) is vaste so this mosaic could be expanded but I think my next plan for the object is to collect RGB with my ASI071 to make a HaRGB image.
