Got some more data last night and have at last a presentable Triffid.
There's still a lot to be done and more data if possible but it actually looks like a piccie!
Great effort indeed Jen, a bit of work to go but you are sure getting there, well done.
Jen I was always told by some to center images of this description, I took no notice as i reckon a bit off set looks better, do it the way you like it Jen.
The subs were about 3 mins.
I'm slowly working up the subs - the camera doesn't always seem to like long subs - it sometimes has a green band across the bottom and I haven't worked out why
Are you imaging with a DC power supply or batteries?
I found when imaging with the 300D and 350D that I got better results when using the power supply. It may have been an issue that was rectified with later models.
Canon batteries I was told heat up when they discharge and this increases noise by heating the sensor. So the theory is to use the power pack so it doesn't heat up. I used to use the power pack but can't say the batteries gave poor results though. I imagine the effect is subtle.
