Albireo 4 mins 10q4 dss 1600 2.jpg

I must do more contrasting double stars.  This was with a 1000mmFL  SW 10" Quattro.

Pleasantly pleased that the diffraction spikes came through on the main two stars.

Have tried to maintain the colours  on processing, but things happen !! in Photoshop.

That really looks nice. I have never tried to image Alberio, would filters (like a UHC) help bring out more colour contrast?

Good question.  I probably had a CLS  (light pollution filter) on when I took this. Depending on the wavelengths it excludes then some doubles will benefit I guess and others will not.  I imagine it is the same for the UHC and Nebulosity filters, depending which wavelengths are transmitted etc...

Obviously stacking and  a bit of PS can cause many things to happen  ?
