SO heres an image of Plato and the Straight range with a relatively high sun angle. The prime day to try and shoot for craterlets in Plato would have been the night before so I was shocked to see how many I had captured!

One thing I am noticing with this ASI camera is that I can process the final stack far more aggressively than with my old camera, plus with almost no artifacts creeping in!

http://img822.images...95/platoas2.jpg

Again, 18" Starmaster dob, ASI120MM camera, R/IR filter 2.5X's powermate, stack of 350 out of 3200 frames.

cheers

Mike

Nice run of lunar images, Mike. I've enjoyed all of them.

Thanks very much Paul, Redzuan, Toxman, JP, Gary and Darryl!!

I'm super happy with this image but still dream of the day I can pop in the 4X's barlow during close to perfect seeing!

maybe this spring!

Amazing Mike! When you shoot with 4x, NASA will decommission the LRO.

Thanks again everyone!! I had to buy a WD 2nd hard drive for my Lenovo laptop (7200rpm 750Gb) just cause ithink theres going to be a lot of video captures in the next couple months!

Robert maybe in a few years I will have enough to publish something, but to tell you the truth I enjoy the more informal online approach!

Sedat: well I don't think anyone here on earth will ever get to the 65M resolution of the LRO, I think the ESO 8 meter got to 170M res using adaptive optics, but maybe they should let the so called "amatuers" try with one of Sams cameras!!

Hi Mike,

Outstanding work! :)

We will have to count the craterlets on Plato's floor and see what we come up with and then keep this tally as a world record to shoot for with 18" and smaller scopes!

Congratulations on a masterpiece!

Best wishes, Dan :cool:

Thanks Dan! How many craterlets did you count? My friend Wes Higgins did an amazing shot (bigger image scale) with his 18" scope some years back:

And of course the record for highest res Plato has to go to Jean Luc Dauvergne using the 1 meter Pic Du Midi scope, but thats hardly an "amateur" instrument :)

Mike, wonderful image. As it happens, I'm processing a similar image and wonder if you would share what gain you were using? My image seems noisier than yours with many more frames.

Heh. That would do it. I'll go look up my gain but it wasn't 5, that's for sure. I notice now that you use an R/IR pass. I used the Baader 685, so I got less light than you.

Back now: gain was 40. Brightness was also 10, I didn't realize that could/should be changed. Thanks.

The one other thing I note is that I got a faster frame rate than you. I ran at 32fps (32.2 to be exact). You might not have the latest driver from Sam which speeds things up considerably).

I have been off too much time!

This one rivals my "standard" of Plato this far (Wes' picture, which I have kept since he published it).

It is amazing what levels of resolution you all planetary people are achieving. It is an incredible time we are living on today. You are reaching levels only orbiting spacecrafts could get some 30 years ago.

This is remarkable, people.

I wish I had more time to be around.

Paul: I actually did have Sams latest driver, but iwas using ram buffer before and had problems with shifting frames, so Torsten sent me a fix and I think (actually I know) that I forgot to reset the disk buffer from 8Kb to 128Kb so I should now be getting 32 fps again.

You might try just the R filter instead of the IR, like you said more light but if the seeings good more resolution too!

Thank you Madrid Sky! Wes's image is certainly amazing, but he has a new camera too (Grasshopper Express) so hopefully he will get back to the moon!

cheers

Mike

Mike, as people pointed out, you certainly got inside Plato MANY craterlets too!

Your picture will also get inside the same folder as Wes' image, so that the day after tomorrow, if I get to Plato, I may do some comparison. :)

WOW!
