Sunday Sun 17th March '19
It has been one of those 'hit and miss' mornings as far as the weather goes. More misses than hits, with lots of heavy cumulus and small gaps and occasional showers. Luckily I managed to dodge the worst of it.
Here are a few shots with my Tecnosky 125mm/f7.8 APO Doublet fitted with a APM 2.7x Barlow from Astrograph + CaK Lunt B600 Module with Omega and Baader Cak-line filters mounted on the nose of the Barlow.
Basler acA1920-155um camera
Genika Astro capture
AS!3 stacking
ImPPG deconvolution
PixInsight colour
I'm still trying to find the optimum equipment set-up and processing settings. I hope these are not filled too much with artefacts from ImPPG.

and an inverted one....

Pushing the exposure I even managed to capture a looping prom.... a first for me in CaK.

Not the best quality image, but.....
Thanks for looking.

Nice results Stu! I managed a few shots before the hail showers set in.

Hi Stu,
Very nice CaK images with 125mm scope! You can easily rise the scale up at 2x and images will be only better! Now they are really undersampled.

Re: Sunday Sun 17th March '19
Many thanks Mark/Marty/Valery.
Valery, I totally understand and agree. These were imaged just above my neighbours roof tops, between a tree and a lamp post with the threat of rain at any moment. Not ideal, so I figured I'd use the faster frame rate of the IMX174 chip rather than the IMX250 with smaller pixels, but somewhat slower capture rate. A bit of a compromise, but when the conditions improve I'll certainly be using the IMX250 as this is closer to the critical sampling scale with this set-up.
Cheers.

These look pretty good to me Stu. I love that little loop prominence shot!

Hi Stu...
Your CaK images are very sharp, and nice to see that loop prom too
