Subject: Mars image Nov 13/05 - advice?


Hi all,


This is probably my best attempt at imaging Mars through my 17 year old TV 76mm 

Oracle refractor - a triplet apochromatic.  I simply cannot get any more detail and I 

think the focus is optimized as is the brightness.  Is this simply a function of small 

aperture?  


Again taken through a 5x Powermate at approx f37, 120 ms exposure stacking at 

80% confidence level with a Unibrain webcam.  BTW there was some discussion than 

the Unibrain has a nonstandard thread/size and I know for that reason that Mogg 

won't make an adaptor for it.  I found some plastic electrical conduit threaded pieces 

that you screw directly into the webcam case (after removing lens assembly)  and 

some light sanding brings it 1.25 " size.
