Soap Bubble Nebula
With every reasonable expectation of failure, I thought I'd have a crack at the Soap Bubble tonight (better known by the catchy title 'PN G75.5+1.7') - up close and personal with the C9.25. This is an example of an object I'm happy to record - at all, rather than devote my life to, and on that measure I'm happy enough with the result. It says it all about how amateur astronomy has come on in recent times: discovered by amateurs with a 160mm AstroPhysics instrument in 2007/8. This one: C9.25/0.63FR, AZEQ6, Atik460EX, Celestron OAG/ZWO ASI120MM-S, Baader 4 x 1800s Ha + 2 x 1800s OIII. Basic processing in Nebulosity/Photoshop Elements. Horrible blue Baader OIII halos. Very pleased with how the AZEQ6/C9.25/OAG arrangement is performing.
For the avoidance of doubt, the nebula is that very faint circular thing just to the right of centre. Some of the stars appear to have their own bubbly halos round them; that is just an optical defect in one of the filters.
