Collimation or wobbles?

[Kaptain Klevtsov]

Got a go at M57 last night but the stars were all smeary like the collimation was off. I re-did the laser alignment but it wasn't much better. I'm wondering if it might be a wobble rather than collimation so I've posted a frame for you gurus to have a peer at.

What's the verdict guys?

Not collimation, I suggest you align your camera with the axes and try again. Looks like a wobble but with the camera aligned you can see which way it is...

Have you been at the falling down water Capt, cause it sure looks like a serious case of the wobbles to me!

Actually I was ratted later, but the Skelescope had been put on autopilot during our soiree and all of the frames came back spoiled. They were spoiled, to a lesser or greater degree, by the effects that show up in the attachment. The lesser messed up ones were lower quality as well (as in cloudier) so the overall contrast was lower as well as the abberation contrast. Popped out to turn everything off and shut the shed before the serious drinking began (big cheque in the post will pay the bills for this month and next) so I was disappointed when it didn't come good.

Arthur, I'll try that next time. Have to PM Kain to book a night of no cloud for a really good trial.

Thanks for the replies guys, I'm hoping that the Skelescope can outperform the OMC140 otherwise I'll have to get a bigger Mak. or SCT.

Looks like the aligning and the collimation are off to me. The stars are trailing (alignment) and it looks like the collimation is buggered (not a technical term )

It's definitely not alignment as the stars stayed in the same place on all the frames. The same mount on the same pier carrying the Mak. gets great results with only PE problems which show up as a waving back and forth across the frame of about 1/10th of the frame.
