    This is my take on M101. 36 x 600s Lum, 12 each RGB @ 600s. Processed in Pixinsight. Comments and criticisms welcomed as always. i@v encluded a cropped version too although there seems to be a lot of things going on in the background of the widefield.

    Today finally some time outside with the dob. The moon now 48% illuminated schould give some nice detail along the terminator. First up Mare Imbruim, the Terminator splitting up both craters Aristillus (55 KM) and Autolycus (39 KM). The daylight side showing some spectacular force of nature caused by the impact. And these two are just small craters. Down to the south Mons Bradley a beautiful mountain massif in the Montes Apenninus region. Hidden in this mountain massif lies a near perfect round crater Conon. Great stuff, the day light lets it pop out. realy nive crater in the middle of a moutain region. Next up Rima Hyginus, 220 km long and showing lots of detail, I guess that the the position of the sun was just right tonight. Just a little bit more south the Rimae Triesnecker, crater Triesnecker (25 KM) is a eye catcher on it's own. So many canals in that area, there's a lot to explore. I really enjoyed that area. Last object, Crater Walther (almost 140 KM). It has a offset central peak. Only the top was lit by the sun leaving the rest of the crater in darkness, a stunning view. Great evening following the terminator. Also made a picture to test the focus range. greets Gert

    Fab report and images, Stu Have had a little post lunch session. It’s noticeable how much both spots have moved since yesterday. The smaller spot which is like a trail of small spots seems to be fading. I guess this may just down to its position on the disc. The kids all came over for a look. Here’s my eldest at the eyepiece. Note the Harry Potter “observing hood”

    Very nice report and photos Stu. I have been out most of the day observing and it’s the best seeing conditions I have had this year. Even managed to get good views of the granulation.

    Sark would a good place to live for observing. No streetlights and cars are banned so no light polution. This is the kind of “traffic” you’ll find on one of their main roads.

    I live on the eastern edge of Exmoor. It's so quiet that I can often hear the trains on the West Somerset Railway which is at least three miles away, and sufficiently dark that on a heavily overcast night you genuinely can't see anything at all. Really. I love it here and it works well for astronomy (when the skies are clear), but the compromises you have to make to live somewhere like this aren't ones that work for everyone. Buses and taxis are pretty much unheard of. It's a thirty mile, hour round trip to take our children to school each day (and the same to pick them up, obviously). Delivery food? I'm sorry, but this is the 1950s. We don't have that around here. Nor a pub in walking distance, or a supermarket within ten miles. The internet connectivity is rubbish (Streaming video? You have got to be kidding), "next day" deliveries sometimes arrive next day and the post might arrive by lunchtime. Tomorrow. I do actually know someone who doesn't even have electricity. Not "no mains electricity": none whatsoever. So whilst living somewhere "dark" might sound appealing, a certain mindset may be required to stay there permanently. Not everyone is ready for civilisation. Not that I wouldn't recommend it. Just don't move too close to me, ok? :D James

    I caught the waxing crescent partially occulting the Beehive (M44) on Friday night! This is a single exposure, f4.5, 1 second: It was a challenge imaging the beehive through the powerful glow of the moon! Cheers, Reggie

    Waxing crescent, about 35%. 8SE out, waiting. 42mm Revelation, x48 - clear, white, bluish background. 36mm Baader Aspheric, x56 - ditto. 30mm ES 82 deg, x68 - more mag, but not as white, plus Ring of Fire effect. Undoubtedly good EP, but perhaps not so for lunar? 30mm Revelation, x68 - clearer, cleaner, no RoF. 24mm UWA Meade, x85 - again, less clean, RoF, but better fine detail. 20mm UWA Meade, x102 - ditto, with less RoF. Theophilus and Cyrillus were most noticeable, with only slight shadow to eastern walls. 8.25 - very good detail, not too bright. Tried x339 for fun - washed out. Pulled back to x203 - good, wobbly; x145 - clearer, steadier, very nice. Two peaks/mountains plus a smaller one in Cyrillus very clear, plus the peardrop crater (Cyrillus A) in the floor to the west. Well that's phase one. There's still a lot of blue up there, so I'm hoping to see stars soon for the first time in about a month! Doug.

    This is the 2nd shot from my recent trip to the dark sky location . approx 51 images stacked @ 20secs a mix of ISO 3200,6500 & 10000 Sonya7RII Tokina F2 20mm Firin Lens Milkyway by Danny Kenealy, on Flickr

    Hi, Ina caldera is among the hardest to observe features in the Lunar 100 list. It is a D-shaped depression of unclear origin. Detailed pictures made by LRO show a peculiar surface. as it is only a 64 meter deep depression it will not show significant contrast when light grazes the surface. However, since the albedo of Ina is significantly brighter than the surroundings it shows reasonably well when the sun is high over the lunar surface. Dimensions are a mere 2.9 x 1,9 km so high magnification is required. The image below was taken on September 29th 2018. Using my CFF 300mm f/20 telescope and ASI 174MM camera. Pixel scale is about 0,19" per pixel, or about 350 meter. enjoy., and feel free to comment.
