Here is another stab at Mars from the window-sill.
This time the configuration is with an Altair ADC between the X3 barlow and the camera. The extra spacing involved turns the X3 into X5-ish.
I had to “wring its neck” processing-wise to see any detail, but of course you have to bear in mind that it is only a lowly ST-80 through the double glazing!
Still, I fancy that some of the detail is real if you compare it to the Stellarium snapshot, and also with the splendid images here http://spaceweathergallery.com/indiv_upload.php?upload_id=146775&PHPSESSID=dgfiuql6dlb877kjt1fkbn4in4
All the images are rotated to put the S pole at the bottom.
Mons Rumker is a lunar dome way out towards the moon’s limb, making it challenging to image from the window-sill.
Sky and Telescope, in https://www.skyandtelescope.com/observing/a-little-guide-to-lunar-domes/ says
“Mons Rümker forms a large, pudding-like mound of some 30 domes piled one atop the other in far western Oceanus Procellarum. The feature appears quite foreshortened near the limb – – – – – – The mound is about 43 miles (70 km) across and climbs to 3,608 feet (1,100 m) above the plains. Rümker represents multiple, massive outflows of lava. Amazing!”
I have been waiting ages for the correct lighting conditions, and tonight was the night!
Mars is at opposition on Friday, but very poorly positioned. Rummaging through my archives I found these images from the opposition of 2005, when the planet was much better placed. I couldn’t find the original jpegs, so the image below is a scan from my notebook. You can see how rapidly Mars reduces in size post-opposition.
They were taken with the 8″ f/10 SCT with a X2 barlow and the Toucam.
Here is an attempt at Mars from the window-sill from the other night when I couldn’t sleep. Only just got around to trying to process the image. It was a 1000-frame avi stacked in Registax 6 /Registax 5 and processed in GIMP (I can’t get the RGB align to work in R6 with W10, but it works fine in R5) You can just about see a feature or 2. (The 2nd image is from Stellarium) – not surprisingly though, not as good as Neil’s. I didn’t deploy the ADC, which I now have, as it doesn’t work too well on a short focal length refractor.
Now 2 days old the moon at 11% illumination presented it self in the evening sky at an elevation of approx. 12 degrees at 21:30, easily visible, unlike yesterday when I could only pick it out using binoculars.
Its companion this evening was Venus, easily visible unlike mercury of the previous evening. Didn’t have to travel any further than front lawn for these shots.
