The Rudolph Nebula
« on: Dec 20, 2011, 19:25:21 »
Taken Sunday night (18 Dec) - a fantastic dark night - after midnight I recorded SQM-L readings of 20.99 (converts to a naked eye limiting mag of 6.1),  the highest I've yet recorded at either High Halden or Rother Valley.

60 x 5min at ISO 800 + 8 x 2.5min at ISO 400 then the clouds rolled in before I could do the shorter exposures.

Usual set-up:  H-alpha modified Canon 350D on Tak Epsilon 180ED with CLS filter.  For the first time I also used a dew shield on the Tak.  Temperatures dropped to -4.5C and there was thick frost on everything.

P.S. The usual processing sequence was followed by a very special operation in Photoshop  ;)

Lovely image Mark, and you can nearly see the velvet on the antlers.

Anyway I believe they have renamed the Wizard Nebula.  ;)

Just for interest, and for comparison with other recent H-alpha images and because Tony prefers monochrome images, here is the red channel only:

I've only just opened the full size version and seen the nose  :lol:

Also noticed a great amount of detail in the dark nebula, particular lower right.
