As I slowly ramp
up the exposure times for this new instrument, a wealth of deep
sky splendors is emerging. This image ranks as a close to the
schmidt camera as I can achieve digitally, and the fast f/4.7
ratio is revealing deep images in a short period of exposure
This image is dominated
by the large and rich open cluster at the top called M47, and
its attending planetary nebula - the red disk within, NGC2438.
You can see that this cluster is a mix of both blue and gold
super giants in the larger images. Below center is the exciting
splashy bright open cluster M47, both cluster are seen easily
with the naked eye on a moonless night. Several other objects
indicated are especially interesting as well.
Several smaller objects
are of interest in this field. NGC2425 is small but contains
several very nicely colored stars. The large and faint splashy
open cluster NGC2423 on the right is pretty monochrome, but has
a definite boundary.
Lets not forget the
blazing yellow star to the left of center - Thats 4.97 magnitude
SAO153227, an amazing K3III type star with a B-V index of 1.6.
The smallest star images
on the original frames are tiny squares. This is from under sampling
such tight and small star images produced by this instrument.
I am running somewhere near 3.8 arcsecond per pixel in these
