Sun images of May 9

[krakatoa1883]

Seeing continues to be all but good, we are still waiting for an anticyclone (any would be good) that seems having no intention to arrive. Heavy storms are expected for the next three days so I have used at least this morning for taking few images in WL, CaK and H.
AR12822 evolved to class C with 15 spots inside plus several pores, the leader spot has a well developed penumbra. Another active region started to emerge close to the E limb south of 12822, this morning was only a couple of pores, few minutes ago there were two tiny but well defined spots. Thanks for looking.

Always a pleasure to see your images Raf, I particularly like the first mod shot, I should find the time to get my Lunt50 working again...

Excellent images Raffaello, very, very nice ! The FD's are sharp and the Ha close up of the AR is beautiful. Well deserved SPOD.

Very nice on all three. White light is pretty much what I saw today.

Thanks for your comments, much appreciated

I should find the time to get my Lunt50 working again...

so far I have adapted the Lunt PT to four refractors, Skywatcher 150/750, Tecnosky 115/800, Takahashi 90/500 and Celestron 100/900, all with 104 mm front D-ERF. The least satisfactory was the small Takahashi because it was impossible to place the etalon at the right distance and because of strong vignetting. The Skywatcher 150 gave fine images but slightly aberrated due to SA in the C-line. Best were the Tecnosky and now the Celestron is spite of the f/ratio.
