Re: Solar imaging session (20190711) | AR12744 (QUARK)

Hi Pedro,

Congratulations with your close up image of a tiny 12744 cycle 25 evidence! Love it, it really nice.
As seen, even with such a seeing you are already limited by the aperture size.
With better seeing this will be more obvious.

Re: Flats from near full disk?

The only method which is correct and which will help is: place a white cloth or white piece of paper in front of the objective and record a flat field movie with about 60% histogram fill. One will need to increase the exposure and slightly increase the gain to fill the histogram. If it will be too n...

Re: Mostly spicules from July 1

Hi Lou, Seems you have a good progress with aperture use. Spiculaes are well seen at the limb and on the disk. However such a configuration works well to a some extend only. Working F/20 is too wide cone and does not allow the etalon to work close enough to it's native narrow bandwidth. The best way...

Re: Cycle 25 Bright Points

Thanks, Mark for your detailed info.

I still do not see any cycle 25 evidences in my telescope in Ha.

When will we see even pores related to C25?

Re: From June 29 and 30

Hi Lou, Very nice start with new equipment. And pretty looking setup. You definitely need to try to image the sun early morning if you have such an opportunity. During last four years I imaged the sun mostly early to mid morning. Good seeing is a very rare event after 9:30 at my location. Also I do ...

Re: Warm Sunshine & New Camera - 27th June

Very nice series of images, Mark.

Impressive for a blank sun. With greater activity will be fantastic.


BTW What was the exposure duration in a DS mode? And what was the final F/D at the chip? Which reducer was used?

May 16 2019 AR12741 and a limb prominence at a high resolution with a 280mm.

Hi all, The sun is spotless for a month now - since May 19. To remind you how the sun looked a month ago, I present you two images from May 16 2019. I took these two photos with my old C11 280mm F/10 Smidt-Cassegrain telescope equipped with a full size ARIES 295mm dielectric energu rejection filter ...

I may be interested in the case this Quark has good uniformity when centered at Ha core and is narrow enough for good contrast.
