Clear skies and little wind, along with a gibbous moon in the sky when I got home from work on Thursday meant I was itching to get outside and get some scope time. I was also keen to try out my 10mm 68 deg fov Baader Hyperion eyepiece I got last month, this fits mid way between the 15mm 50 deg fov Televue plossl and 7mm 110 deg fov APM XWA eyepiece. There's a double rationale for the choice of glassware, all give a full disk view of the moon, it's just as the seeing allows with the shortening focal length of the eyepiece then also the size of the full moon varies with magnification whilst still retaining a full disk view - if that makes sense. The other side of the argument is that I plan to use the LZOS 100/800 for WL solar, and, the SM90 also has a 800mm focal length, so, in the weeks ahead the same family of eyepieces will also work for solar...
Anyhoooo, here's the 71% gibbous moon, I used a barlow to fill the fov of the chip, but this was only imparting something like a 1.15 amplification factor...

Seeing was borderline for the 100mm aperture, with only really the last image fully supporting it. Makes me feel happy I chose the 100/800 as this seems to be where my seeing is at most of the time, and the best scope is the one you can use the most
Hope you like, rain forecast all weekend now, so no chance of the sun (or moon!) for a while again...

Re: 71% Gibbous Moon - 10th February
These are great Mark, it is nice to see you enjoying yourself in the dark again
Weather was very different here last night, we could see a very foggy hazy Moon so went out for a walk, the wind was bitter, then it started to rain heavily and yet we could still see the misty Moon?

Re: 71% Gibbous Moon - 10th February
Well done Mark on your nocturnal efforts.
At least you got some clear-skies for those, whereas here - no such luck again.
Even during Friday, as soon as I got a Solar view, the pesky-clouds rolled-over from somewhere before any imaging...
Thanks vm and hope the weekend here does not run to the "forecast"...

Great pictures, Mark! The quality of the lens is excellent. It was interesting for me to "walk" on the surface, and when my daughter saw it, she said: Oooh!
