I have only owned the 400D for a couple of weeks & got to use it 2 or 3 times so far due to nasty weather.
Here are some images from the camera & a DSLR newbie using a 5.5" F3.6 schmidt newt on EQ5 no guiding/PEC control. All taken 27th dec. 06' & all 1st quarter moon affected
The Rosette: Not an easy capture, its huge! & it's low surface brightness makes it hard.
8X2 min subs @ 1600 iso / 4X2 min subs @ 800 iso. (taken in small JPG format) 2 different processing versions uploaded.
M42: An easy one to get, only I forgot to get some short exposures to control the burnout. I also made a botch of things processing it, I'll get better though
Approx. 12 X 2min exp.
The Crab: Its a small object to capture with my setup so I had to crop it serverely. Needs more exposure time to get the filaments. 5 X 2 mins.
The pleaides: 2 X 2 mins. Gotta get more subs stacked on this one.
I'm quite happy with the 400D so far but a 20DA it ain't
Cheers.
