Hope you are all having a lovelly Christmas!
This image is of Eta with the 40D through a WO FLT110 and this is my 1st serious attempt at this subject so I am probably a little rough on the colours.
Details :
Modified 40D through FLT110 on a G11
ISO 800
12 x 600 seconds
Darks + Flats
Guiding through Meade ED 80mm with NexGuide
Stacked in DSS
CS4 was used for levels, curves, saturation, selective colour but not too much involved at this stage with my limited experience with Eta.
This subject is certainly very red!! I think the 40D has picked up a fair bit of Ha.
The 1st image is the full frame
2nd is a crop at 75% to show what's going on. You'll see I have lost a lot of star colours and this could be due to the 40D rapidly saturating and not the same dynamic range as a dedicated CCD. I would love to hear any improvements, critique etc. Focussing was done with a Bahtinov mask.
All the best for the festive season and thanks for looking
Darrin...
