[geoflewis]

Here is my first look at the Deer Lick Galaxy Group.

The data was captured over 3 conescutive nights 30 Aug - 1 Sep 2019.

C14 + Optec x0.63 telecompressor; QSI583wsg; Astronomic Type 2 LRGB.

All subs 300sec bin 2x2. L=42, RGB=18 each. Total 8 hours.

Thanks for looking.

Lovely detail. Some nice star colour too.

Many thanks Daz and Bryan. I did wonder about extra saturation boost for the star colours, so may take a look at that, but I'm encouraged that you like it as Bryan.

I think the saturation is fine. The bigger/brighter stars have burnt out, as they do, but there is still colour around the edge. I can't remember off hand how you do it, but there is a technique where by you reduce the bloated stars size and spread the colour which survives around the edge into the middle. I'm desperately trying to remember where I read it, but it's not coming to me at the moment!

Either way I would be very chuffed with an image like that. 😁

Thanks Brian, if you do recall the technique for blending the edge colour of stars into the star centers I'd love to have that please. I've also seen that process described previously, but like you can't lay my hands (or memory) on it. I seem to recall it was was using a mask and blurring the star layer, or something.... 🤔.
