Hi All,

Can anyone tell me the best way to eliminate shutter vibrations of the OTA
whilst doing astrophotography?
I have a 10" Lx200 and I'm using a Nikon FA 35mm camera, I have just bought
a set of counterbalance weights which I have not had a chance to try out
yet.
Any suggestions?

I plan to start using an autoguider soon with a guidescope and I want to
eliminate this problem before hand. I'm hoping that the counterbalance
weights may do the trick, I used to use a piece of cardboard with black
velvet on it to hold in front of the OTA,
trip the shutter, then after a few seconds remove the card from the front.
Culd it be that in the past I didn't have the weights and that it was off
balance?

Has anybody had similar problems/remedies?

Thanks in advance,

Andy.
