20260423 Solar Imaging

Didn't do solar imaging for quite long.

Just upgraded to a ASIAir Plus in order to do planet/solar imaging, so given the great sky today, why not?

I always love my nearly 30 years old Tele Vue Ranger, it has been given a new life with a JMI NGF-CM focuser, and better yet now with a ZWO EAF!  It keeps on evolving.  

I also got a solar finder for it, very effective indeed.

Centering the solar disc cannot be easier.

Despite seeing is no good, fine focusing with the EAF is lovely and accurate.

I took two videos with 1080 ROI, both hit the limit of 4G maximum file size in less than one minute.  Frame rate is good with this little box, I couldn't get too much more with my aging Windows laptop.

I am now stacking the videos by using the ASIAir Plus, seeing is less than optimal so why not do a simple processing from out of the box?  Stacking one video of 4G took more than nine minutes, not exactly fast but it might be faster than pulling out my Windows laptop.

Below is processed with a laptop, the ASIAIR version will be uploaded later.  I don't really have patience in this kind of seeing, so the exposure and mosaic was actually unusable.

Somehow I lost that image processed from out of the box with the ASIAIR Plus, anyway, my impression is that it's pretty nice.
