Bubble in Ha with Quattro and 1000D

[Carl M]

Didn't have to wait too long for some clear skies to try out one of my Christmas presents - an Astronomik 12nm Ha clip filter. I was also glad for once that the moon was up so I could give the filter a good test. This was my first attempt at a narrowband image so found focusing a little difficult, don't think it's quite spot on. When processing I saw double diffraction spikes which suggests it was out by just a tad.

This is 15 x 10min exposures at ISO1600, with just the red channel being used after stacking in super pixel mode.

Quattro 8s on EQ6

Full spectrum 1000D

Very pleased for a first go, could certainly do with some flat frames which will be done in due course.

Any advice or criticism is appreciated. Think I was a bit heavy handed on star reduction, but I do like minute stars in mono images.

Cheers,

Carl
