Well I figured I'd give it a try tonight although it wasn't exactly perfectly clear out. I'm not an expert by any means but I just like astro stuff. Anyways I used a 40D with a 100-400 and 2x III attached. Mounted on a tripod (Cost $1 from a garage sale), cable release, and mirror lockup. The tripod worked but was frustrating to use as after I locked it in the camera would slump down a bit.

Settings:

SS: 1/100
f16
ISO: 500

Thanks for the comments. I cropped it, added some contrast, played with the levels a little bit, did some noise reduction then sharpened. Nothing to fancy as I'm not that good with the editing yet.

It is good for a single shot. If you could take a series of images and stack them together and play with the wavelet transform, the sharpness will goes up a lot.

I want to know more about this method.

@OP- that is a really nice sharp, I do not think the Tc takes much if any IQ away.

Yeah I'd like to know more about this as well. I thought you really couldn't stack images of the moon...

Thanks I'd like to try again on a clearer night and with a 7d for the pixel density!

[QUOTE=Paxonator;13828​555]Yeah I'd like to know more about this as well. I thought you really couldn't stack images of the moon...

You can use registax to stack images of the moon/planets, but I've personally never got registax to work for me (it always crashed). I've tried stacking it manually, but it never lined up completely for me when I did (probably atmospheric distortion or something).

Stacking wouldn't necessarily help improve sharpness though...it'll improve the signal to noise ratio, which isn't normally a problem for the moon unless you're shooting at higher ISOs. Personally I just shoot to the right in RAW and bring down the exposure in post.

I would like to know what other programs besides registax that do the wavelet transform though...

Yes, stacking won't really increase the sharpness. But as the S/N ratio goes up, wavelet transform will bring out lots of details. This is particular true when imaging planets.

Some close up shots taken last year. These mosaic images were stacked from videos.

Thanks for the info! I was just viewing your thread where you used the astrotrac and 55-250. That is something I'm definitely interested in getting into! Just need to read and learn more....

I was thinking about the astrotrac too but apparently you will need some knowledge of the sky to use the same. It was suggested that I use a go-to type of mount first. You may want to ask those questions before you get the astrotrac.

Yeah I will be doing a lot of reading before purchasing. I had thought either the astrotrac and a good tripod or get like an orion EQ-G. Oh and I need to quit buying things haha, but it's all too much fun!

No matter what the hobby we all seem to get GAS.... in the "end." That's Gear Acquisition Syndrome BTW .;):lol:
