Description

After battling with HOO and HaLRGB versions of the Ghost of Cass, I decided to step back into my wheelhouse on this one... I love capturing dusty dark nebula targets, and this is my favorite time of year when the nights are relatively long and Cassiopeia and Cepheus are high in the sky.  There is so much interesting "stuff" in this region of the sky and with the e160ed and IMX455 the FOV is so large that it puts some perspective on these objects.  You can capture so many targets, big and small in the same frame.  

I've imaged both these primary targets before, but never together.  I think it would be an amazing project to mosaic this entire area, but I'm a bit intimidated by the idea and may hold off for another season.  

This is my first pass at processing the data.  As always, there is something that I want to tweak but cant put my finger on it.  I find that just putting it out there sometimes helps to inspire me on what I want to work on.  I find your feedback very helpful in guiding my hand on the final tweaks.  I think maybe I need a little more color in there.  I've only captured an hour of each channel, and at times like these I find no matter how much I push the saturation it doesnt seem to line up well with the luminance application.  The only real solution is to capture more color data.  Perhaps another night spent gathering data would be time well spent.  So for me, I'd like to see a little more color information, but not just a saturation boost.  These are some faint structures and I dont think I have enough photons. 

So on that note, your comments are very welcome!

Captured with Tak Epsilon 160ed, QHY600, unguided on a Mach2 and first time using Astronomik Deep Sky LRGB filters.  Since these filters are thinner than my Chromas, I needed to reduce my spacing which of course put my tilt management out of whack.  I spent a little time roughing it in before imaging, but my toes got cold and I wanted to image.  I need to add a little spacing and adjust tilt, so I'll refine on my next outing.

Description: I needed some more color data so during the 82.5% moon a couple of nights ago I broke the rules and collected a few hours of RGB data. It did the trick! It got my colors where I wanted them and I decided to push the dust a little bit less for a slightly more natural feel.

I plan to post the RGB only data taken during the 82% moon to show people that they shouldnt be scared of the moon! The data was quite good despite the conditions.
