No extraordinary images for this lunation, because of the turbulence and the use of infrared filters.
Here are some images of the 24th, I am working on those of the 25th which will be of the same style.

Just a quick enquiry ... was strolling the lunar surface on Iroc and bumped into this area of florescence on the lunar surface.
Any thoughts anyone? (Co-ordinates at bottom of screenshot if you want to get better definition from original website).
Was struggling to see clear heavy impact crater that would account for the wide spread of surface debris?
Didn't think it was image flare - not expert on that so could be wrong - but noticed on RHS there appears to be traces of surface debris scatter?
It almost seems like someone threw a very low velocity ‘flour bomb’ at the surface of the Moon?🤨
Have there been mineral studies done on these areas of exceptional lunar florescence? ... I tapped the phrase into SGL’s Search ... but surprisingly it came up with ‘no results’??
Headed out for the Cancer & Bootes "Full Moon Doubles Match" I'd originally planned for last Friday & that time ended up abandoning due to scrappy seeing , wind & the onset of rain.
All observations with SW Mak 127 on AZ GTi, Baader Zoom 8-24mm via Tak prism.
Transparency good but a little high mistiness & locally occasional ground mist from the river. Temp around 5 degrees, air quite still.
Aligned Arcturus & Capella.
Seeing excellent - steady Airy discs and diffraction cones above 30 degrees altitude.
Spent some time looking around for & sketching the Cass Nova area, not sure I saw it as M52 not really apparent in the moonlight. Identified a possible candidate in the starfield but needs another look & maybe when better dark adapted/less moon.
Castor (Sep: 3.9")- Clean-split white-blue pair with 18mm (83x). Southerly star the larger of the two. Lovely stable view- steady Airy discs with diffraction rings. Confirmed excellent seeing.
Iota Cancri (Sep: 30.6") - very pretty, wide-spaced, side by side pair. Split with 24mm from 63x. Orange primary, white/blue secondary. Super view at 16mm *94x). Stable Airy discs.
Tegmine, Zeta Cancri (Sep: 6" & 1.1") - Split to 2 stars with 24mm (63x). Peanut shape on B/C revealed at 120x and definitely resolving as 2 faint secondaries with 8mm @ 188x. Overlapping cones/rings but quite distinct central discs. B at 7 o'clock to A. C at 5 o'clock to B, (RACI). Seeing must be really good as splitting the secondary is right on the optical limits of the rig at 1.1".
(Chuffed with both the prism purchase - this was essentially why I upgraded - and the fact that I've clearly got lots of astronomy mileage in the Baader Zoom before that department needs upgrading! )
Spent a long time on Tegmine savouring the 83 year old view. Dragged myself away & turning north east the moon was casting long gothic shadows through a low mist, spilling across the field toward me at knee height from the river. Felt like the set of the Thriller video...
Aligned back on Arcturus for Bootes orientation - so bright. Golden yellow sun. Lovely.
Espilon Bootes, Izar (Sep: 2.9" ) - Split at 8mm, 188x. Once identified could see dialled back to 120x. Brighter yellow primary, smaller bluer second - looked "behind" the other. In each other's cones but distinct. Found it initially quite challenging.
Xi Bootes (Sep 7") - Split from 24mm, 63x. Off white primary, small orange secondary at 11 o'clock. Quite lovely.
Tawny Owl hooting now to go with the moonlit mist. River mist actually has cleared somewhat. Auriga to West hanging spectacularly. Can hear the town clocks striking midnight across the fields, so still. Gorgeous night.
Kappa Bootis (Sep:13.5") - white pair, larger primary, second at 10 o'clock. Also, a pretty trapezium due South, top R corner pair may be double itself. (Confirmed yes, is Iota Bootes (Sep 38.7), with a slightly wider field this would be a double-double).
Mu Bootis - Alkalurops (Sep: 108.9 & 2.2") - Wide spaced initial pair, both white. Dim second is at 7 o'clock, maybe double? Shielded moonlight from EP & yes quite sure of it - C faint and at 2 o'clock to B, resolves at 8mm (188x). Clean separation & once achieved almost easier to see with these fainter stars. Another fab one this!
39 Bootis (Sep: 2.7") quite close white pair at 5 o'clock.
Struve 1825 (Sep: 4.4) - faint white second at 7o'clock. Clean space between. Lies about 1 fov N of Arcturus (just over a degree).
Tired by now I blew out any slight night vision I had by looking at the crinkliest bit of moon I could find, up to max power (428x, 8MM Barlowed x2.25) - turned out to be Mare Crisium region. Views were astonishingly crisp up to c 340x. Apparently there was a TLP square thing I could have seen, certainly enjoyed the shadows from the mountains there and, childishly, the fact that there is one crater named after an Enterprise Captain & another called "Lick" (I know, Jean Picard was a seventeenth century French astronomer...)
A few final equipment notes:
Telrads dew up really fast. Astrozap shields really do work. Redlight filter for iPhone applied in Accessibility settings & toggled from main control key makes a big difference, no more app alerts popping up with blinding effect!
Hometime for a celebratory cup of tea (well it was a school night after all).
This image is a compilation of my captured images of Mars during this years (2020) opposition season of Mars. All of the images were taken using a 8" SCT at 6764mm focal length (f33.3) with an Celestron Skyris 618C CCD. All of the images were taken with the same telescope at the same focal length so shows the size of the martian disc as it was closer, at opposition and further from Earth.
