NGC6995 5 hrs data 2 nights 16 & 17 Sep 19.jpg (402.56 KiB) Viewed 2215 times

So this is 5 hours data on NGC6995 from Bortle 6 skies here in Manchester, around 300x 60 sec lights with flats, darks and dark flats. No LP filter used.
Scope is a 6 inch RC with AP CCDT67 reducer, camera is a ZWOASI294MC Pro OSC running at 120 gain and -10c. Mount is a tuned belt drive EQ5, ZWO guidecam and scope.
Stacked in DSS, processed in Startools and some final tweaks in Adobe LIghtroom.
C&C welcomed. Either in terms of capture or post.

And yes Ivo, I know I'm still not dithering .
I need to get APT and PHD2 to play nicely first, which is proving rather harder than it should be.

Dithering or not - that's impressive! Especially from a Bortle 6 zone.

Thanks Ivo. The wipe module is helping considerably in removing the LP gradients without messing up the image. Clearly though the LP Is still masking faint detail. Might be getting some form of LP filter in a bit and trying that "luminance with filter and colour without" that we were discussing and that v1.5 now supports. V1.5 gives me better images, but the new version of decon and the final noise reduction when tracking turned off are definitely in the "go make a coffee" category.
