Moon 15 August 2013

Last night's moon.

145580

This was a single shot 1/200s @ ISO 100, using the Astro Physics CCDT67 FR on the scope for the first time. I'm quite satisfied with the result since this was certainly a "lucky" shot. I did some video as well and the atmosphere was roiling so much I couldn't get anything really useful from it.

Take 5 like this & stack them.

Nice result.

That shot looks pretty good to me Chris. One frame, ON YA Mate.:thumbsup:

[lazjen]

Bit of a facepalm moment for me when I read your post. I don't know why I didn't think of this at the time. Hmmm, I do have a couple of others, but slightly different exposure times...



Thanks. It's also one of the rare shots I've got that when I look at it "100%" it still looks quite good.

[asimov]

Different exposures should still stack ok, Chris:thumbsup:

I was just trying with Autostakkert, but it seemed to hang while processing. At least it did better than Registax though, which completely crashed.

I was using the TIFFs directly converted from the RAW images. Maybe they're too large for the program to handle.

[asimov]

I stacked 8 images tonight in AS!2 from the 7D. Yes it will take awhile for the program to crunch threw them. I should point out it'll hang & stay hung forever if you are trying to do 2 images. Apparently the minimum is 3 images. Mine were just straight JPEG's.

Are you using version 2.1.0.5?

[lazjen]

I've got 4 images. Version is 2.2.0.16 Alpha (can't remember now why I went to this version). It's getting 96% done and basically hanging on the MAP Analysis phase.

[lazjen]

Just went back to 2.1.0.5 and I'm making more progress. First attempt succeeded but the alignment was woeful. I'm on my second attempt now, but I might have gone a touch insane on the number of alignment points...

[asimov]

Lol. Some things will boost the insanity levels, & this can do it if you let it:lol::eyepop:

I know it sounds silly, but try just one (200 in size) in the middle on a small crater..

Edit: And hopefully they were taken with a tracking mount. The moon needs to be in pretty much identical positioning in each frame.

[Solar]

When it does that Chris JUST let it hang and get a coffee it will do it.

[lazjen]

Ah, yes a tracking mount, but I didn't align it properly - my main aim for the night was to sort out different configuration setups (FF vs FRs vs 2x Barlow), so the moon was a juicy target for it all. There's a bit of drift between them. I guess I could crop the TIFFs to fix that and give it a go.

[lazjen]

Let's just say that it would have been a very long coffee. So much so that I would have gone full cycle to the *next* coffee with seemingly no progress. (Ok maybe I haven't let it go that long). I'm sure I gave it greater than an hour, probably more with no luck.

[asimov]

Yeah if it doesn't do it within 1 - 1.5 mins it's never going to do it & there's a problem somewhere. I'd crop them central, convert to JPEG & just try 3.
