Saturday Sun and AR2670

[Carbon60]

The morning was beautiful with wall-to-wall blue sky and very stable seeing. My SSM displayed values between 0.8 and 1.2, which is pretty exceptional for my viewing situation over rooftops.

AR2670 was my main target with my 150mm/Lunt35 mod in DS mode on a 2.5x Powermate. Such were the conditions that I even shot a couple with a x5 Powermate. Usually this is impossible, but, given the aperture of the scope, they came out quite well. I'm still preparing my adapters to utilise the larger scope (250mm) so I'm not quite ready with that one yet.

The FD is a mosaic of six heavily overlapping panes captured using my DS Lunt 60 with a 2.5x Powermate.

The final one is a close view of AR2670 with my 5x Powermate on a 72mm f6 refractor with B600 Lunt CaK module illustrating significant plage around the decaying former AR2665.

Basler acA1920-155um used for all images.

Thanks for looking.

Wow! these are fantastic!! what a pity the big telescope isn't ready because if you had such good seeing a WL shot of the spot would have been awesome

Many thanks, Alexandra. The parts should be ready tomorrow, all being well, so we'll have to see what the weekend brings.
