The Dark Tower

I always wanted to image this object after seeing fantastic renditions from Marcus (marc4darkskies) and Don Goldman, so here's my first attempt.

I was able to get quite a lot of Ha from home but good quality RGB was much more difficult to come by. I managed a few hours under dark skies/without clouds over the past couple of new moon weekends and got a lot less than I would have liked, but I won't get more until next year...

Scope: Ceravolo C300 @ f/9 = 2760mm FL, Atlas focuser
Mount: AP900
Camera: U16M
Filters: Astrodon E series Gen 2 LRGB, 3nm HA, OIII, SII
Guiding: Lodestar / MMOAG
Image scale: 0.67 arcsec/pixel
Exposures: 58x1800s Ha, 7x900s R, 7x900s G, 8x900s B (29 + 5.5 hrs)

Processed in PixInsight.

High res version on Astrobin: http://www.astrobin.com/126037/

Cheers,
Rick.
