Sun September 8th 2021_RCT Images
I thought I'd give my 250mm RCT a run this morning. The seeing conditions were pretty good, although there were some contrails and a bit of high level variable haze to make it a bit more challenging, as if it isn't challenging enough at these image scales. I'm really pleased with the new etalon housing configuration which is working perfectly with everything aligned and with the etalon really easy to tune.
My focus was the two main ARs 12866 and 12868 which were captured using a 2.5x Powermate and Basler acA1920-155um camera. I used my usual Genika Astro for image capture, AS!3 for stacking, ImPPG for deconvolution/sharpening and PixInsight to refine the final images. My RCT is fitted with a full size Aries ERF (triband) and an internal barlow lens to make the output light cone parallel for the Lunt 35 etalon and refocusing lens. Thanks to Valery for tips on processing. Still a work in progress, but Improving, I think. So much also depends on the conditions, as we know....
Anyhow here are the images.
First up is a mosaic of the two ARs in question:

...and the individual images of the two ARs:

That was it for today and for a little while now we've got some weather coming through with an Amber Warning for thunder storms.
Thanks for looking.

Very nice images Stu
The two regions have been very active all afternoon with some nice bright flares moving through them.
The sun is interesting at last.

Re: Sun September 8th 2021_RCT Images
Wow Stu, such excellent images to behold. The RCT is certainly very able and these are just great.
And yes thunder-storms are very likely too.
Thanks for sharing

Re: Sun September 8th 2021_RCT Images
Hi Stue,
Some real improvements in your RCT images.
Do you use SS or DS etalon? I believe the DS is the way to go (even with some gain increasing to keep the exposure shorter).

Re: Sun September 8th 2021_RCT Images
Thanks, Valery. I might get around to making this a DS setup sometime, probably by fitting one of my Lunt 60 modules in front of the Lunt 35 with suitable machined adapters.
Anyhow, I've been playing around with the settings in PixInsight (Linear Transform Function which is smart sharpening, and deconvolution). By experimenting with the parameters and the order of the applied enhancement processes I've ended up with a much better result (I believe). The risk, of course, is overplaying it and making the final image look overworked. I think I'm getting there with this hi-res stuff.
Here's the original stacked image from AS!3
20210908_AS3_Stacked Image (RCT) by Stuart Green, on Flickr
and here it is processed in PixInsight using combinations of sharpening and deconvolution on the finest scales.

Compare this with my previous effort on the same image and the difference is clear.

I'd appreciate your opinion and comments.

Re: Sun September 8th 2021_RCT Images
Deconvolution in Pixinsight is my primary sharpening method, but I'd never thought to try linear transform function. I'll have to play around with that. Looking good!
