A Whole New View
Astrophotographer: Chuck Kimball
“It’s the best eyepiece I’ve ever had.
It showed me structure through my
telescope that I have never seen
before. I was just delighted!”
- David H. Levy

NGC 7000
& IC 5070
This tiled panoramic image by Kimball captures two worthy emission nebulae in the Cygnus Constellation. Located near the
brilliant star Deneb, the North American Nebula (NGC 7000), left, and the Pelican Nebula (IC 5070) are separated by a dark lane.
Equipment used to acquire this image includes an Explore Scientific ED80 f/6 with an ES field flattener, a Canon XT/350D DSLR
modified by Hap Griffin and a custom saddle on a modified Meade LX200gpsR fork. Exposure times were 414 minutes for IC 5070
plus 132 minutes for NGC 7000.
Long Eye Relief, Hyper-Wide
The 92° LE Series Waterproof eyepieces
provide a hyper-wide apparent field of
view with long eye relief for comfortable
viewing that immerses you in vast
expanses of the star-studded sky.
NGC 6791
Kimball took this photo of
open cluster NGC 6791 in
the Lyra constellation using
an Explore Scientific 208mm
Newtonian with an ES coma
corrector, a Canon XSi/450dH
DSLR modified by Hutech and
a custom saddle on a modified
Meade LX200gps fork. The
final image is a stack of 37
five-minute exposures. Kimball
said, “This cluster reminds me
of Trumpler 5, but seems to be
older, at least part of it is. It is
another oddball, having stars
of three different age groups:
one group of white dwarfs at
4 billion, another group at 6
billion, and the ‘normal’ stars
at 8 billion years. Most open
clusters contain only similarly
aged stars. I will watch this
since it really challenges some
core methods of aging stars.
I like the possibility that the
younger set may actually be
doubles which would naturally
appear brighter, and skew the
results.”
