For
the past year I have been using a MallinCam Color Hyper
Plus (MCHP) video camera with my 24" and 15" Dobs
on their Equatorial Platforms. Results have been very satisfying,
not only with obtaining images, but also with "live"
viewing using a monitor right at the telescope. A group
of people can be observing all at once using this powerful
camera, as it puts a new image up on the screen every 2-58
seconds. The camera has remarkable sensitivity and yields
fabulous color, as can be seen in the single shot downloads
posted below. The view on the live screen was every bit
as good, if not better, than these images.
All
of the images were taken at integration times of either
2, 7,14, or 28 seconds. All of the exposures were unguided,
using an Equatorial Platform for the tracking. The first
group of photos are all single exposures with minimal processing
(mostly just brightness/contrast). The second group of photos
are stacked images of 2-5 exposures and more processing,
such as you might do with a regular CCD camera. While the
MallinCam is not intended to replace high-end CCD cameras
with much larger chips, it can still make some nice color
pictures -- with exposures measured in tens of seconds instead
of minutes or hours.

Stacking MallinCam Images
The
following images have been created from 2-5 exposures stacked
together, with some image processing after that. The individual
exposures were either 7s,14s or 28s. I'll be posting more
pictures as they are taken.
