Hi guys.
I know I have threads on these objects somewhere on this site, but I can't find them!
Anyway, This handy little item for fine focusing is for those that can't afford an electric fine focuser. Before I took up astrophotography it was real handy, & now even more so since astrophotography! It does take some time to get good focus before capturing but the results are well worth it. (seeing conditions a factor here)
My rough N' ready dew sheild & cross hair illuminator has been a real blessing! The illuminator is out of my EQ5 polar alignment scope. The shield is just a bit of thick plastic rolled up.
The other night I was out imaging & my illuminator batteries ran out of juice. There was a very dull glow but not enough to see the cross-hairs so I was some-what stuffed for getting mars on my laptop. No access to new batteries at 3am...so what do you do??.....I cut a 1cm square of alfoil & glued it on the inside of the dew-shield directly opposite the globe of the illuminator & PRESTO!! Could see the cross-hairs no problem!.....Still haven't replaced the batteries & that was over a week ago! :lol:
