While fitting the Littrow, with the Cube Beamsplitter to the 12" LX200, the 1 1/4" fittings rotated and dumped the spectroscope onto the floor, via a couple of bounces of the edge of the table!!!
You know that feeling you get when you cut yourself with a sharp knife??? Just like that!!
A lot of bad rattling noises from the spectroscope.....
That was on Friday, the 26th ( double the 13th!!)
Pulled the spectro apart and found the collimating lens had been knocked out of the holder and it had dropped forward onto the grating!! Some slight scratches on the grating, but not too bad.
The slit and prism etc seemed OK.
Took the best part of the day to re-set and re-glue the collimator, a mixture of using the laser beam and Cheshire eyepiece.
Today ( 1st Oct) finally got the chance to check the focus with the Canon 350D body.... looks OK.
So... I've already made up a holding bracket which will positively clamp the body of the spectro to the Meade scope. This MUST be used all the time!!
