C9.25 star test at x1175 mag

Hi Guys

Last night I plugged the x2.5 TeleVue PowerMate and a Takahashi 5mm LE eyepiece into the C9.25 and imaged Sirius almost at the Zenith.

This is the result of 4 frames from 1200 in Registax3.

Focal length of C9.25 = 2350mm.
x2.5 PowerMate increases this to 5875mm.
5mm eyepiece gives x1175 magnification!

The vast majority of the frames were mushy and distorted, but 4 seemed quite round so I stacked them just for the heck of it!

Cheers

Dennis
