Eta Carinae again

[Asterix2020 (Paul)]

Took some new subs last night and discarded the green ones.
I think I've done something wrong with the colours in Startools, it seems a bit oversaturated now. 9 subs. 45 min total. Advice appreciated.

That looks fantastic... makes me wish I didn't try to deyaber my DSLR and just left it Ha modded, effectively destroying the sensor.
I have another sensor to replace the dead one, just waiting to have time to put it back into the DSLR, ofcourse I will be attempting to debayer again... this image gives me inspiration.

Pat,
My camera is a 600D modded and cooled. You can see it here http://www.centralds.net/cam/?p=1687.

The green ones were on my first attempt: http://www.iceinspace.com.au/forum/s...d.php?t=118991

Got to be happy with that. Just a tiny bit of streaking on the left hand side. Focuser or adapters a little tilted?

[Asterix2020 (Paul)]

Not sure. I thought it was coma and a field flattener might help? It is present in all the edges, this image is slightly cropped.
Here is a full frame of one sub. Do you think this is field curvature (and a flattner would help) or flexure (and therefore need a better focuser)?

[cometcatcher (Kevin)]

Ah okay, going by the full frame looks like field curvature. A field flattener should help.
