Magnificent Sunspots II - White light closeups 4/22

Cschur · Post by **Cschur** » Sun Apr 22, 2012 11:33 pm

Greetings All,

More white light images from this mornings session. Seeing was around 2/5 which means the granulation was occasionally visible. These are close ups with two instruments, first the Zeiss 80mm f/6 + 5x Televue Powermate, and second with the AR152 stopped to 4 inches (100mm). Once again, I can say for certain that I have never seen such a variety of large detailed spots on the sun surface! I hope you can get out and view /image this appearance.

Lets start with the 80mm shots first:

And now a few with the AR152 stopped to 4 inches due to poor seeing:

Lovely images Chris, some look just like paw prints on my leather lounge

Serious scale on some of those shots, nice despite seeing and the stop down.

Thanks guys! It's so much more fun when the sun is showing off, isn't it?

You can clearly see that four inches is really the minimum for really serious work.

Excellent images all round there Chris! Definitely agree 4" is the minimum really needed, problem is in solar seeing conditions pretty much always being the prevailing factor that limits what we can and can't do...

These are excellent images Chris! seeing these makes me desperate to get out the WL again. I only wish I had more time at the weekends and mainly more sunshine at the weekend too!

Regards
Alexandra

Chris the very last pic seema to be the sharpest in terms of granulation. But your pics with the 80mm has me wanting to pull out my 80mm APO just to take a look. Thanks for the update.

Thanks everyone! Looking forward to see what the spots will do this week. Mark, my experience lately has been that if the seeing is better than 2/5 the six inch is always the highest resolution. 2/5 and lower the 80 mm or 4 inch is sharper. Seeing is determined first then, with the 80mm on the pattern of the granulation, then if its good, I step up in aperture!

Alexandra, Ill have a talk to the cloud gods for you so youll have more sun on the weekends.

Hi Chris:

Great images. I am missing all the fun: Rain during the last weeks and it seems that it will stay like this for one more week...

best regards
