South of the Tarantula
Hi all and hope you had a happy and safe Xmas.
Thanks Mike and the IIS team for this, second to none astro group.
This is a bit of a work in progress. It is a hard area of sky from my location at this time of year due to temps, dust and wind.
But I really wanted to get some of these beautiful knots and bow shocks created from the wonderful Tarantula Nebula.
This area of sky is just south of the Tarantula and you can see it just to the top of this image.
It is quite grainy. I need a couple more hours of Ha to smooth things out so it is a work in progress.
Such a large dynamic range and it was real fun trying to combine Ha with its makings of nice detail to the rgb.
Details:
Scope- 10" Newtonian working @ F4.6 (with paracorr)
CCD- SXVR-H16 1.32arcsec/pix
Guide- SX OAG & Lodestar
Filters- Anti Halo type II- 2" Astronomiks
Ha- 168' @ 7min subs
RGB- 56' each @ 7min subs.
Pre- process- Flat fields & bias (no dark subtraction)
Here's a link to the unfinished image

Hope you all have a great year in 2012 with plenty of clear nights.
All the best
Rich
