Very nice images, and processing!

Chris

Well done with Mu!

Simple ND filters work well with my 180 Mak for Mars and Jupiter, showing a lot more detail which would otherwise be bleached out by the brightness of the planetary disks, particularly at low mag.

Chris

Certainly a nice one. It has been visible even in my 15x70s at peak. I used my ED80 last night away from the village lights, and it was still an easily visible stella point with averted vision.

Shame it didn't reach the same brightness as the 2011 SN in M101 though.

Chris

Very nice detail!

Chris

Nice. Probably not optimum lunation for the craterlets?

Chris

Very nice Neil!

Chris

I'd agree with more mag. I can see the colours far more readily at high mag (180 Mak) than with a low mag, wider field view, when the individual stars appear as white pinpoints.

Chis

Your resolution should be about 2x better than with my scope (180 Mak) which on a night with good lighting and seeing showed these.

Chris

Nice - the Plato craterlets are just starting to show.

Chris

I posted this by mistake in the observing forum and couldn't delete it for some reason.

Petavius at sunset two nights ago - I love the way the light moves across the crater and rim in quite a short time, making it quite a "transient phenomenon" I suppose.

Mak 180 at about f20.

Chris

Just managed to catch it. The seeing was poorish unfortunately, due to the heat plume from my house. 180 mak at about f22.

Chris

sorry, should be lunar imaging. Moderator, can you move pl.?

Very nice images Geoff!

Chris

Reasonably good seeing, although the scope was covered in frozen dew!

Huygens is visible just to the left of Syrtis, which is bottom right on the disk. There may be some cloud or haze visible bottom left??

180mm Mak at f22, using an ASI120 Colour camera, best 10% of 30,000 1 ms frames, processed in PIPP, AS and then sharpened in Registax.

Chris

If it's of any use, in practical measurements my 180 Mak with a camera with 3.75 micron pixels does show more detail at f22 (6x pixel size than f15 (4x pixel size) if the seeing is excellent.

Chris

A very nice view of Plato. Interesting to see how it differs from a image with a smaller aperture, for example with my 180 Mak (attached).

I know it. I haven't been to do so with my current equipment. My largest instrument is 180mm.

Just about visible some years back with my 180 Mak.

Chris

Very nice!

Good for you Peter, Mars is glorious with the naked eye!

Nice image Chris. Great details coming through. What exposure were you doing?

These were 5ms, which is certainly sharper for me than 10ms (6000 frames at 5ms, cpd with 3000 at 10ms). I tend to get noisier images with Winjupos.

Chris

Nice detail. Certainly with my 180 mm scope, the shortest frame times  seem to give me a better result with my limited skills, for example.

Chris

Nice image - Olympus showing clearly.

Chris

Very nice images a nd presentation!

Chris

I was hoping to stay up for the occultation itself, but my laptop gave up before I did. Mars at 23:30 with a 180 Mak.

Chris

Superb!
