Images with MINTRON 12V1C-EX and SCT 20 cm f/10 with focal reducer
effective focal length f=675 mm f/3.3, field of view 0.56 x 0.41 deg

Captured with a resolution of 720 x 576 pixel. Image size for the satellite images on this page is 0.4 x 0.4 degrees.
This is about the field of view of my most used eyepieces with the 20 cm SCT (Criterion Dynamax 8 from 1978).

The views with the Mintron are far better than those with my best eyepiece (a Meade Series 4000 "Super Wide Angle" 67 deg field with f = 13.8 mm).
I need high magnification in my bright, suburban sky to see faint stars in it and want to have a large field of view to find them.
With the Mintron camera, I can see fainter and thus more stars as with my best eyepiece.

Pluto 2003 June 26 and 27
150 and 162 frames added with FitsWork. One frame is 0.32 seconds. Total integration time 48 and 52 seconds.
V magnitudes are from Tycho 2 (11.0 - 12.0) and derived from USNO B1.0 (14.0 - 14.5),
The conversion from USNO B1.0 magnitudes to visual magnitudes is described here.

The sane frames added with Registax.
