Dear friends,
Still trying to catch up...
Please find attached some images of the Sun in H-Alpha and CaK from July 25th pluss an 80 min timelapse of AR2847 and "the mustache filament".
FD image in H-Alpha using a Takahashi Sky-90II with Coronado 90mm/BF15, Coronado 2x CeMax and ASI 1600mm PRO. Sun FD in H-Alpha 25th of July 2021
FD image in CaK using a William Optics ZenithStar 61II stopped down to 46mm, Lunt CaK 1200 module, Coronado 2x CeMax and ASI 183mm camera Sun FD in CaK 25th of July 2021
Sun FD in CaK 25th of July 2021 - colorized
Close-up image of AR2847 and "the mustache filament" in H-Alpha using an Explore Scientific AR152, Baader 2" 35nm H-Alpha (as ERF), Daystar Quark H-Alpha Chromosphere and ASI ZWO 174mm camera. Sun in H-Alpha 25th of July 2021 - AR2847 and "mustache filament"
80 min timelapse of AR2847 and "the mustache filament" using the same equipment as above.

Great animation, wonderful details and love the sinuous movement in that large filament! Great job!

Very nice indeed, Arne.
Superb closeup view.
How do you find the ASI 1600mm PRO? Can you see/image the disk and proms at the same time (maybe if you adjust gamma)? I'm looking at purchasing one for myself (for use on my Lunt 60 + 2.5x PM FDs), but I'd be interested to know if the dynamic range is adequate. I can easily see both disk and proms on my Basler cameras without resorting to multiple exposures.

Re: Sun in H-Alpha and CaK 25th of July 2021. Closeup of AR2847 and 80min timelapse
Thank you very much for your kind comments Terry, Warren, Mark and Stu.
Stu: I'm very happy with the ASI 1600mm Pro. I can certainly see both disc and prom features if I adjust gamma slightly. All my FD images with this setup (Sky-90II, Coronado 90mm frontfilter + BF 15, Coronado Cemax 2x) are single recordings with neutral gamma setting and processed to show both disc and prom details.
Please don't hesitate to ask if you would like to have access to some raw recordings or stacked (but not processed) images to help you with your decision process!
Best regards,
Arne

Thank you very much David and Franco.
I'm awaiting my copy of the September issue of S&T to arrive here in Norway.
