I think the first one is the best i've ever done !
It's a very natural processing : no specific layer for the proms, so the spicules are present. The overall dynamic is quite surprising !

I'm currently starting to test my mods to the coronado SM60 and the blocking filter. It's amazingly better than with the stock version !

I'm still working on it (I receive some equipement just today) and i also wait for a KG3 filter for more security in SWIR.

Nevertheless it's already a success with more details and more contrast !

Until it's over here comes already a 5 fields mosaic with a couple of barlows (x2 + x3).

It's resize at 80% as it was a bit oversampled

Equipment : 

Coronado SM60 double stack modified, BF : Bandpass 6A  + bandpass 5nm, FS60 & IDS 3370 CMV4000.

At least the weather was fine enough to try the brand new IDS uEye3370 built upon the very fast and large CMOSIS CMV4000, here standing by the Basler 640's ICX618 :

This camera throughput over USB3 is 77 fps right now to extend to 90 with the next firmware. In 12 bits it drops to 38 fps, but that represent still a huge 320 MB/s that my Crucial M4 cannot handle completly. A new Genika Astro release supports that knid of throughput.

Here is a large HA mosaic using the FS-60 with two coronados 60mm and a x3 barlow. Given the FWHM of the filters and the F/D fringes are unavoidable on such a large sensor.
