Meade ETX125 and Fujifilm XT1 and Orion Nebular M42 & Moon

My ETX125 has been sitting idle for quite a while as I've been exploring the world of camera only Wide Field Astro.

I thought it was time to have a go with my new camera. With its very sensitive sensor the long focal length of the ETX may not be as much of a problem, so off to the shed to make an adapter.
The following Pic is taken from our Backyard in Melbourne Australia, never gets very dark where we live. I'm pretty happy with the result.
This is stack of three images, no cropping, the ETX has a narrow field of view.
I'm finding with the Fuji camera that reducing noise by stacking, whilst helpful, is not as important as it used to be with my old camera. A good single image with some "curve", "contrast" and "wavelet denoise" works well, all done with "GIMP"

I tried some more imaging on the following two nights, with poor results due to periodic error.
I must have just been using the good part of my drives "worm" this night. Gives me something to think about... A new mount maybe.
