    I haven't been on the site much but I thought I would post a somewhat recent image I took of the moon. My EPL5 was mounted on my 100 ED refractor to give me a focal length of 1800 mm. 6 images were stacked together for best results. Cheers! Karl

    Great moon image, maybe the best I've ever seen! But what is an 100ED Refractor? It sounds like a telescope, and thus what kind of interface do you need to the camera?

    Definitely a telescope of some sort - usually there are t mount adapters that are available for various mounts, I have one for K mount myself though don't use it often.

    And agreed with everyone else, that is definitely a great shot!

    Very nice! I wish my reflector had that flat of a field of view.

    Wonderful image!

    A question about:
    Would that be focus stacking, or HDR?

    I'm guessing for noise, you don't really need DOF (it's _almost_ at infinity :) ) and the DR's not out of range...
    Best moon shot I've seen yet...would love to hear more about the rig/see pics!

    100mm aperture (ED is the type of glass for low dispersion). There are many such beasties like this one. Lots of different interfaces as well - depends on the exact model and other accessories one uses. Most generic would be a MFT-1.25" eyepiece but I prefer a MFT-2" eyepiece. T mount is also quite common. The larger scopes can have 4" mount or a custom even.

    One can easily go into the deep end and spend $3000+ on such things but they can also be had in the $500-800 range if one looks diligently. Naturally one can spend much more on a mount to cradle and guide the scope ... so many ways to spend large sums of money in astrophotography.

    Oh yeah, that image is way too sharp - I think I cut my eyes! Momma!

    Thanks for the comments. My scope is the Skywatcher 100 ED (low dispersion glass) f/9. I purchased a T-mount adapter for my EPL-5. All shots are in M mode and the moon is bright enough for decent shutter speeds. The reason to take a lot of images and stack them is due to atmospheric turbulence, which can cause havoc on sharpness. There is some excellent software out there for stacking images. One key bonus for the micro four thirds is the weight. Seeing that the EPL-5 doesn't weigh much, my telescope has no issues when I am doing astrophotography. Using even an APS-C DSLR, things change a bit, as the weight increases a fair amount. The last thing you want is your camera falling off!
