Hi all,
this is the culmination of a broken corrector plate, a couple of hours capture and a couple of days of processing.
Enjoy!
The movie is on the bottom of the page.

Cheers, Baz.
Baz,
Broken corrector plate? That's simply terrible! What on earth happened? How did you repair it?

I didn't. I am still waiting on quotes and info on replacing it as I beleive it has to be matched to the primary and secondary as a set. It may be worth buying a new socpe. It will never be top of the line again, but I was pleased with the results though. It's like running with a blister. Sure you can still run, but it hobbles you a bit.
The crack came from one of the screws holding the retaining ring on. Our winter this year was minus temps every night for a few weeks and I had a 20 degree spring day. It doesn't take a genius to see how it happened.

Ouch!! :roll:
Baz,
Is that the scope you did all that hard work on - the Peltier cooling? If so, you must be even more gutted.
Still, I reckon that crack would make very little difference to the final image except that it might disperse some extra light where you don't want it. I might be wrong though ...

It'll depend a bit how much the figure of the plate changed as a result of the stresses relieved when the plate cracked, I guess...
