Re: 45min timelapse of retreating sunspot and partial disc

Thanks! However, after seeing your latest shot of the new sunspot moving around, I think I may have been confused on what I myself was imaging, as I think my animation is actually of that new sunspot and not the old sunspot, since I can see a defined sunspot in my still image from that same session...

Re: ANOTHER LARGE SUN-SPOT GROUP IN THE S.E.LIMB - Tuesday 3-11-2020

Thanks vm Rusted and certainly shows that hopefully a lot of action might follow - judging by your close-up capture. Cheers Terry I was seeing bright little spots [flares?] in the AR region just as I lost the sun to the trees. 15.15[CET] Hopefully we shall have something to follow judging by what i...

Re: ANOTHER LARGE SUN-SPOT GROUP IN THE S.E.LIMB - Tuesday 3-11-2020

I managed to capture the spot this morning. It showed the umbra and penumbra of the leading spot but little else. The seeing was coarse saw-tooth on the frantically boiling, solar limb, between almost continuous cloud. Worst seeing conditions ever! The sky cleared to blue as I crossed to the house a...

Superb animation and image. :bow

The fleeting filaments give the animation an almost organic, "pond life" appearance.

Re: 29.10.2020 The same spots but sharper.

Thanks. :bow The etalon is just a thick cylinder of glass in a solid sandwich. Access is not easy if you still have the etalon cell glued to the PST. Once the cell is free then access is straightforward. Mark has a well illustrated piece on the subject. Scroll down to near the bottom: https://brierl...

Thank you all, yet again, for all your kind words. :bow The seeing was not great, due to thin cloud, but the lack of wind allowed better results today.

29.10.2020 The same spots but sharper.

After struggling with uneven illumination for ages I wrapped my PST etalon element in Teflon plumber's tape. This was to achieve better collimation and was an obvious improvement in more even lighting across the image. Same image, different levels of processing: 29.10.20 14.17 b1200 1.6x GPC.jpg 29....

27.10.20 Southerly gales and endless clouds.

Despite the difficult conditions I managed to capture the multiple spot AR in the SW.
I've had to close up now in case the dome inflates and takes off across the fields. :o
It is very noisy and cold in the dome. Not a great image I'm afraid.
