I'm batching tonight, so for the first time in a couple of months I haven't had guests or family to entertain... so finally I've got a chance to play with the Spectra L200.
After imaging the sun this afternoon, I set up to try to set the focus on from the L200 to the ST8. I found a few little problems to solve.
The weight of the ST8 is proving a little problematic. I had modified my 2" EP holder to include a second locking screw to secure the Vixen flip mirror and spectroscope and camera, but despite the screws being tight, the 2" EP holder unscrewed
. More muscle required there next time.
The other area where the weight is a problem is the Baader sliding focusser. Depending on orientation the camera moves in the focuser. I went through the motions practicing focussing the ST8 on the slit/grating anyway, but I'll have to do some mods to add more locking screws to secure the camera once I get it focussed for real.
Does anyone know of a good supplier of M3 or M4 thumbscrews?
ATM I'm just using ordinary SS screws and a screw driver, but the right sort of thumb screws would make a very professional job of it
.
