Hi!
Everything is in the subject: CaK pictures taken on June 26th with a 250mm newton combined with a TZ5.

Any chance you can post a raw unprocessed animation so we can get an idea of what the camera sees in real time?

Wow!!!!

Thank you Alexandra.

TheSkyBurner, posting an unprocessed animation is quite heavy, but here is one frame.

Some comments from my side.
I'm testing various “barlow” combinations. Here, with a telecentric x5, thus the resulting data are F 8750mm, and F/D 35.
These values are much too high for my local site, where the seeing is reasonable, but far from good for high resolution.
The lower part of the histogram is empty, thus there is no information there.

I was only asking because how dark the image was. I am trying to get a similar magnification on my xtruder telescope mod.

I figured a 250mm mirror would provide a super exposure . And your raw frame is a better example.

Processing cak images is a learning experience for sure, so much more sensitive that halpha to wavelets.

here is a sample of what I am seeing on my screen in raw format unprocessed. I am using a pst objective as a refocus lens on +5000mm.
