Sunday Sun 18th July 2021_RCT and 150mm mods
We're having a brilliant weekend of weather here and I've had another opportunity to trial my reconfigured 250mm RCT. Yesterday was diabolical from a seeing standpoint, but this morning the seeing conditions were almost perfect (for here anyhow). The SSM was showing 0.8 arc seconds or better, with averages of 0.8-1.2 arc seconds, so it doesn't get much better than that, certainly from my driveway.
First up some RCT images of AR12842, including a mosaic of 4 panes around the core.

I've resisted over-sharpening these, but even with great seeing conditions they are somewhat soft.
Here's the same region on my 150mm mod at various scales on a 2.5x and 5x PM respectively:

...and a 6 pane mosaic over the same region:

AR12845 is looking pretty nice too:

as is the high latitude region AR12844

That's about it for today.
Thanks for looking.

Well done Stu!
It's good that somebody is capturing some decent seeing.
Worst seeing ever here today!

WOW Stu, what a great set ! As always, conditions are more than half the end results, but these are really super.

Wow!! Stuart, these are great, I think I would be quite happy with the RCT images, but the 150mm really stands out

These came out well Stu! The 150mm shots were spot on for the conditions.
