Having been seriously impressed with this image of the prominence the other day acquired with a Lunt LS152
I thought I would have another go at processing my window-sill image. I screwed down the alignment box size (in Registax 6) to 10 pixels and limited the processing to the prominence area. I then added a bit of Lucy-Richardson sharpening in GIMP. I think the extra aperture of the LS152 allows a much faster shutter speed, limiting the blur due to atmospheric wobble. The result is below.
Not as good as the LS152, of course.
There is also the small matter of a factor of 20-30 in the price of the optics of course – – – – Sigh!
The new sunspot has now got a number – AR2718.
Look at what you CAN achieve from the UK! – http://spaceweathergallery.com/indiv_upload.php?upload_id=147300&PHPSESSID=2m86lk4cf4gr18bhad16c2p4s5
This was with a Lunt LS152 – 4+ X the aperture of my LS35 and serious money! (£11500-ish)
A new sunspot has appeared, as yet, un-numbered. (Later – now AR2718)
Some reasonable features this morning ;—
After imaging Mars, I moved on to image a couple of DSOs in Cassiopaeia.
NGC278 is a small face-on spiral, and after processing, was a pleasant surprise, with lots of character. I think I need to re-visit this one with more magnification at some point.
NGC185 is is a dwarf spheroidal galaxy located 2.08 million light-years from Earth. It is a member of the Local Group, and is a satellite of the Andromeda Galaxy.
Again, needed a bit of extreme processing to extract any details.
Syrtis Major and Hellas are now in full view, and the other features in fact compare pretty well with the map at
Take a look at this for other amateurs’ Mars images
And here is a useful map:
Given the Sun’s current quiet state, some quite nice features today-
Another superficially nice night, but the Mars seeing was pretty poor, and I got clouded out quite rapidly.
Before looking at Mars I had a go at M20, the Trifid nebula, in Sagittarius. This was pretty low at about 11 degrees elevation for a dim DSO, necessitating a fair amount of processing to get anything reasonable.
Mars was like a wobbly jelly. This time I tried a X3 barlow. The ADC is clearly doing its stuff, but it won’t compensate for poor seeing! The Hellas basin was obvious visually – easy to mistake for the S. polar cap!- and Syrtis Major was just about in view.
