the smallest scope to use video cam on

[garethmob]

well im deciding to move away from my unweilding scopes and scale down and so im considering a mini scope instead (megres 72 or skywatcher 66 ect

has any one used a cam on one of these scopes

would a flatner be needed for just viewing? / capturing video?

I took this using a Celestron Neximage to capture video via a WO Megrez 72 then stacked in Registax at almost three years ago now:-

The tiny sensor in the video cams will probably mean you can get away without the flattener...

You did spur me on to try something... namely trying the SCB-4000 on the TV-Pronto for a bit of digiscoping of the birds on the feeders... without the 0.5x reducer i can get the close focus using the 2" TV diagonal.. with the reducer there isn't enough inward travel so i had to remove the 2" diagonal and use a 1.25" one or a 1.25" extension..

According to the "literature" the Watec, GSTAR-EX give limiting magnitudes:

8mm f/0.8 lens : 8.5

135mm f/2.8 lens: 12.8

300mm f/4 lens: 13.6

80mm f/5 refractor: 14.2

Whatever! But always worthwhile trying old camera lenses...

Spanking NEW refractors etc. Particularly for wider fields.

Bought myself one of those TS (60mm/F3.8) "superfinders".

Rumoured not to be the "best" achromat <sigh> But...
