Re: Nov. 26, 2020 AR 2786 and 2785

Thank you all for the great comments. This increased solar activity is quite exciting. I began Ha imaging about three years ago and have never seen this much activity. I captured a full disk image with a LS 80 today so I would not forget.

Nov. 26, 2020 AR 2786 and 2785

Hi All,

A beautiful Thanksgiving day for some solar imaging. The active region 12786 was irresistible today. On band and off band images were taken with the 6" Mak and Solar Spectrum filter.

Re: November 5 2020 Observations. New pics!

Hi James,
I have done quite a bit of imaging with an iPhone camera and have found the moon, planets, brighter DSOs and clusters turn out reasonably well but the sun is a challenge. Your images are surprisingly good. Well done.

Re: AR2781 in action - November 4, 2020

Franco,
Great looking images and equipment. Seems like the Combo is working well and on band with the temperature set to mid range. I consider that a good sign with room to shift into both wings. Just shook my head hearing about your SS etalons.

November 5, 2020 Questar/Quark

Time for only two quick shots, so the little Questar went out today. Captured AR12780 and AR12781. Hopefully 2781 will continue to develop. Baader DERF, Questar 3.5, 2.5x Powermate, Quark Combo, 0.5x focal reducer, and PGR Grasshopper GX. Phil 20201105_094822_AR12780.jpg 20201105_090006_AR12781w.jpg

Re: October 30, 2020 bombs away?

Thanks again for the kind remarks. Looking further into Ellerman bombs, one study suggests maximum visibility in Ha would be in the wings at plus or minus 0.8 Å. If the occasion arises I will try again in that wavelength. Unfortunately, the temperature controller I have will not heat the etalon enou...

Thank you all for the comments. One additional bit of info pertaining to the animation, 1 frame per minute recorded 10 frames per second video playback. (1 sec. = 10 min.)

Alexandra, thank you for the analysis. I think I learned something.

Hi All, Here is an off band animation of AR2778 and AR2779 attempting to show Ellerman bombs. Seeing deteriorated rapidly over the 40 min. capture. The etalon temperature was set to 44.7 ºC resulting in a center wavelength of about 1.4 Angstroms into the blue. Truthfully, I have no idea what the bes...

Thanks Eric. Alexandra, I don't have much experience shooting animations but will give it go, weather permitting. If not with this AR, I'll try the next ones coming around. We do have some members here that are great with animations. Maybe they will see some clear skies soon and try as well. Thanks ...

Re: October 28, 2020 AR12778 +

Thanks for the kind comments! This was a fun AR so far.

These etalons shift approximately one angstrom for every 10°C change so the first image would be centered about 0.5A toward the blue.
