G'Day Jay-qu,
Thanks for the filter feedback. It sounds to me that the effect of an LPR is included in the UHC filter and "then some".
The sodium streetlight out the back of my place is obnoxiously bright and makes averted vision all but impossible. My whole backyard is bathed in orange to the point where the reflection off the Dob tube will destroy night vision in an instant if you accidentally look at the scope (and forget putting your eye up to the scope if you are not going to make a full seal around it!). I suspect that the advice of using some petrol to move further away is going to be very sound, but impractical for viewing every night. After all, I'm sure most people like the idea of just whipping out the back or front and using almost all available time for viewing rather than having some of it chewed up for transport.
I think I need a long hood for the Dob and certainly one or more filters. I would hate to damage any threads on any accessories by constantly screwing filters in and out, so two would be best, or a spacer... As it is I find I am changing eyepieces every couple of minutes to keep changing the FOV etc and that's already a pain as is!
I'll be most interested to hear what people claim the "best" EP to be..
Tim
