RMweb Premium Physicsman Posted August 10, 2022 Author RMweb Premium Share Posted August 10, 2022 I see you've been having a bit of fun..... SOME modelling work continues, but these 2 pics are hot off the press having been taken at around 2.20 and 3.08 this morning. Just a quick bit of processing, that will be refined, before I go to bed in order to see what I've "captured". 8 1 2 6 Link to post Share on other sites More sharing options...

Winslow Boy Posted August 10, 2022 Share Posted August 10, 2022 What scale are they Jeff? I was going for OO but others said you'd stick to EM. And most importantly how much DAS did you use. I think its been said but I'll repeat it anyway isn't technology amazing that youve been able to produce such image images is a credit to you. 1 1 Link to post Share on other sites More sharing options...
RMweb Gold Rowsley17D Posted August 10, 2022 RMweb Gold Share Posted August 10, 2022 (edited) Great photos Jeff. Looking at them reminds me of an astronomy module I took at college nearly 50 years ago now. Quietly viewing while chemo no 2 is underway. Edited August 10, 2022 by Rowsley17D From astrology to astronomy. I blame the drugs - chemo ones. Link to post Share on other sites More sharing options...

RMweb Premium Sasquatch Posted August 10, 2022 RMweb Premium Share Posted August 10, 2022 Hi Jeff. Great pics. Have you pointed your telescope at Betelgeuse lately? Regards Shaun Link to post Share on other sites More sharing options...
RMweb Premium Physicsman Posted August 10, 2022 Author RMweb Premium Share Posted August 10, 2022 Thanks for the comments, and don't get me started on astrology! I'm just heading out for 3 hours of Jupiter imaging, though I'll nab a few shots of Saturn before I start. John, widefield pics of meteor showers are something I've done in the past and the Perseid shower can be impressive. Unfortunately it's badly affected by the full moon this year. Shaun, if you'd asked if I'd looked at Uranus....which I have, as it's near Mars (oh dear, you can twist that if you like) not too far from Jupiter at the mo. Betelgeuse has actually recovered in brightness from its dimming- down 2 years ago (caused by either giant star spots or an intervening cloud of dust orbiting it). Some thought the dimming a precursor to it exploding as a supernova (one of the nearest supergiants to Earth at around 500 light years), but nope... Or was it just Beetle-Juice on your mind? Folks, modelling has come to a halt for the next ten days or so for obvious reasons. I have a project on the go which will enhance the layout and will be unveiled when near completion - likely early September. I'll update this thread with any decent planetary pics. If it's not your thing then railway stuff will return with a vengeance....eventually! 9 1 1 Link to post Share on other sites More sharing options...

I hadn't realised it'd been so long since you've been on here. Are you still in the Blea Moor area or back at Hellifield? The layout chugs along with bursts of intense activity - well, "intense" in a reltive way. Underbridge, tunnel, station building etc in a 3 month period. All takes time though - no point in rushing it all in a couple of weeks, getting bored and wanting to get rid of it, is there? I’m still a mom covering from Hellifield to blea moor, down to Blackburn then over to littleborough then to hebeden bridge. The area we cover is big compared with some of the other areas that moms cover. mid I get chance I will get some shots for you. 3 Link to post Share on other sites More sharing options...

RMweb Premium Sasquatch Posted August 19, 2022 RMweb Premium Share Posted August 19, 2022 Hi Jeff. Despite all the smoke from this year's fire season, last night was an exceptional clear sky and what we refer to as a very stary night. Just looking through a pair of binoculars at the center of the milky way was mind boggling. The entire field of view was a pure mass of light. Dim of course but full non-the-less! This morning we've had smoke drift in from California, so I doubt we're gonna be treated to it again tonight. Shame, because I should be getting the truck back after some work that needed doing and could have taken a drive up to the top with the telescope tonight. Regards Shaun. 3 3 Link to post Share on other sites More sharing options...
RMweb Premium Physicsman Posted August 20, 2022 Author RMweb Premium Share Posted August 20, 2022 Hi Shaun. The light pollution where I live isn't too bad, but views of the Milky Way aren't as impressive as they were 40 years ago. The modern generation, I'm afraid, don't know what they're missing. I did a survey a few years back, when I was still teaching. Only 20% of my sixth-form Physics students had actually seen the Milky Way.... I've managed 2 good moon imaging sessions in the last week, and hope to be outside 2-5am this evening. Friday's exploits produced 275Gb of pretty excellent data - half the storage capacity of my laptop. I'll post some more pics early next week when I've had a good sort-through. No railway work, but I did go into the Bunker yesterday - for ten minutes. The stirrings of desire to get back in there are strong, so something non-astronomical is likely to appear on here in the next........weeks - fill blank with a number 4 or greater! Thanks to viewers for your continued interest in the stuff on this schizophrenic thread! Jeff. 6 1 2 Link to post Share on other sites More sharing options...

RMweb Premium Physicsman Posted August 23, 2022 Author RMweb Premium Share Posted August 23, 2022 Here's an image of the waning crescent moon from early Sunday morning. The image is a mosaic of 15 panes, each pane made up from 800 "stacked" frames - so effectively compiled from 12000 sub-pictures. You can zoom in quite a way, but the usual disclaimer - this is a 2Mb jpeg file, compressed from the original 37Mb TIF. Copernicus crater, that you've met previously, is the large crater half way down on the light-dark boundary (terminator). This area of the moon is dominated by large lava plains which are less reflective than the highland areas. It gives the waning crescent moon an almost eerie, "ghostly" light as it hangs in the sky. Almost getting poetic, there! 7 3 6 Link to post Share on other sites More sharing options...
RMweb Premium Physicsman Posted August 23, 2022 Author RMweb Premium Share Posted August 23, 2022 Right, I'll subject you to a couple more pics and then disappear for a little while. Here are 2 pics showing how important imaging the moon at a higher altitude can be. The first is a (quite good) image I've posted previously: July 21, moon at 26 degrees above the horizon. The second is from 4 days ago. Similar area, moon 46 degrees up. The increase in detail and sharpness is significant. The large crater is Clavius: about 150 miles (240km) in diameter - about the distance from London to Manchester.... The view is looking south towards the moon's south pole. 6 3 3 Link to post Share on other sites More sharing options...
lambiedg Posted August 23, 2022 Share Posted August 23, 2022 Thanks for these photos. The difference in the last two is amazing. Meanwhile courtesy of the BBC &Mr Webb….. 9 Link to post Share on other sites More sharing options...
RMweb Premium Physicsman Posted August 23, 2022 Author RMweb Premium Share Posted August 23, 2022 David, do you think anyone would believe me if I claimed that Webb infrared image as my own work? No? Shame. Sums up humans for me. Unbelievably intelligent in evolving from living in caves to today's high-tech achievements. And unbelievable lacking in intelligence for their behaviour on this planet which isn't even the equivalent of a speck of dust in our galaxy alone. Anyway, since I was responding to your post, here's another image from 19th August. It shows the crater Plato (90km wide) and the adjacent (to the right) lunar Alps. These mountains typically reach 3-4000m in height, comparable with our own Alps, but much higher in proportion to the smaller Moon. 6 1 1 1 2 Link to post Share on other sites More sharing options...

RMweb Premium Physicsman Posted August 24, 2022 Author RMweb Premium Share Posted August 24, 2022 A couple of people have asked me what kind of equipment I'm using to obtain my images. This isn't the place to go into immense detail, but here's a couple of pics showing the main beastie in his lair. 2 smaller siblings stand quietly to the side, out of shot. It's a Celestron Edge HD 11" Schmidt-Cassegrain, with all sorts of bits-and-bobs tagged on to the standard outfit. The red "thing" at the left end of the scope is one of my high frame rate planetary cameras. Doesn't look like a camera, does it? 5 1 3 1 Link to post Share on other sites More sharing options...

RMweb Premium John Besley Posted August 24, 2022 RMweb Premium Share Posted August 24, 2022 Wow, can you use that to take pictures on our planet... Or will it only work as a lunar camera?
