15Apr 17 (Singapore) - SF100 single etalon on a 152mm refractor
Setup 1 for Full Disk: SF50 double stacked etalons on a Borg 76mm refractor + PGR Scorpion camera.
Setup 2 for HD H-Alpha: Solarscope SF100 single etalon on a Celestron C6R 152mm refractor + Televue x3 barlow + ASI174mm camera.
First the Fill disk
420 frames selected from 4000 frames
Pseudo colour added in good measure

Great images, Alfred ! I particularly like the second one of surface detail. Excellent processing.

Hi Franco,
The Sun was covered with a thin layer of clouds that just wouldn't go away. I could only achieve an average of 45 frames per second with a shutter of 21ms. Gain was set rather high at 201. Hence the frames were rather noisy and I compensated that by using 420 frames to increase the SNR. I would like to see the image quality with better seeing.
Alfred.

Hi Mark,
Thanks for your kind comment. I have the C6R refractor and SF100 etalons for some time now but have not used them as I had given more attention to the ARIES D-ERFs. I am making an adapter to use a PST Stage 2 mod on a ARIES 8" D-ERF + 8" SCT. I hope to do some more imaging with the SF100 before HA imaging on the C8 + ARIES D-ERF.

Beautiful FD and super HR image with the 152mm refractor.
Best regards, hope to also soon will start using my new 265mm Aries ERF.
Have a nice Sunday,
Eric.

Thanks Eric for your kind comments.
What H-Alpha etalon are you using with the C9.25 SCT + 265mm ARIES D-ERF?

Alfred:
I will use the 265mm ERF for my 10" f/20 TEC Maksutov, and probably also for my 12" f/10 Meade SCT.
As for the etalons, I can use an 0.45A° ATM Daystar, and a 0.5A° modified Daystar T scanner now in a new housing with an internal oven and with a tilt provision.
Both scopes have beautifully corrected optics, the 12" f/10 SCT was hand picked many years ago from dozens of units, each one optically checked.
Best wishes,
Eric.

Lovely images, Alfred. The second one is particularly good. Nice kit.

Hi Stu,
Thanks for your compliments. The second one was made with 420 frames. I did another one with 600 frames.
I can't really tell if there is any improvement in terms of Signal-to-Noise ratio.
