Trapezium A, B, C, D, E, F, G, H & I, Sirius A & B, Full Moon
Hello,
With the return of my repaired EM200 Controller Box from Tak in Japan, my EM200 is now back up and running, so I gave it a test drive over the last couple of evenings.
The images are with the Tak Mewlon 180 F12 and Canon 5D Mk III either at the F12 (2160mm) prime focus or using a Tak 1.6x extender yielding F19.6 and 3456mm efl. The G, H & I stars can be made out in the F12 prime focus image which is a stack of 6 x 20 seconds.
Sirius A & B are straight out of the camera with no processing.
With the full-frame 5D Mk III the comatic stars at the edge of the filed were very apparent.
Thanks Rick, Laurie, Mike, OIC and Al, it was good to be at the ‘scope one more although I was a little rusty in setting up and operating the gear after a longish lay off. Then there was the familiar waiting for the sucker holes…
Great images,Dennis. I like the Sirius shot particularly. What a challenge to photograph this. You've managed to get it exactly between the diffraction spikes.
Cracking work Dennis. The core images are particularly nice. Something that I would like to have a go at myself at some point. If I can get time to do this.

Thanks Graeme and Paul – I appreciate your comments.
@Graeme – some while ago I purchased a set of Parallax Tube Rings for the Mewlon 180 so I could rotate the optical tube, to re-locate the (fixed) top side finderscope off to the side, as it prevented me from using a star diagonal (head hits finder!). A spin-off was that it placed Sirius between the 6 point diffraction spikes from the 3-vane spider!
@Paul – I’d love to see you have a go at this with your set up and imaging skills. I’ve only dabbled so far and the last set was plagued by clouds, so I only managed to grab a few frames in between the sets. If you can find the time, I’m sure there will be a wide audience on IIS who would love to see the results – good luck and don’t keep us waiting too long!
