Thanks. It didn't come with the Quad TCC I have upgraded it to the GTX 3.5 inch focuser, the 3.5 inch flattener and now the Quad TCC.
Glad to see some results through it. The Lagoon's so beautifully captured. |
Thanks very much. This FOV is very similar to an FSQ106 but with larger aperture (585mm versus FSQ 530mm). So a bit like an FSQ130.

Thanks very much. So far the tilt correction has been straightforward. That last little bit was hard to tell if spacing or tilt. Spacing though should really affect all 4 corners so that narrowed it down.

One little thing -
the stars are missing colour.
Would you have needed to take some short exposures - say 10 seconds -
with that QHY600 to retain some colour?
The RGB are 120 seconds which is pretty short. I did have some registration difficulties and the correction may have been a tad harsh. Yes I thought they were a bit colourless as well. I will go back and see if I can correct that. I usually use 5 or 10 minutes much the same as CCDs as this CMOS is 16bit and the short exposure strategy is more aimed at the 12 and 14 bit cameras to get the bit depth up by using lots of sub exposures. The colour is still in the data so I'd say this is a processing question.
cheers

Unconvinced about this colour version though with it's muted star colours, presumably because of the moon being up?
You must be a very happy camper now with these lovely new toys. |
Thanks Andy. Yes the star colours are weak as noted above. I'll go back and see if I can get them more saturated. It should be in the data.

Yes its right up there for sure with the absolute best.

Greg.
