At 11.30pm last night there was so much moisture in the air it was like imaging through fog.  And so hot that even in a tee shirt I was uncomfortable.  It was amazing that I recorded anything.  But I apparently did.

Still fine tuning the spacing for the 0.7 FR, so star images in the corners are not there yet.  Reports say it needs to be closer to 60mm rather than the usual 55mm. Think it needs another millimeter or two.

Reasonably happy with the result for now.

As always, thanks for looking.
