RE: [APML] Orion Min-EQ + EQ-1M
Thom,
What film did you use for the first (mw-wide1) shot? I assume E200
like the Iridium flare shot? (Nice shot, by the way.)

Astrophotography
Andrew,
Having been there/still there myself I can attest to George's comment
about most of the cheaper mounts requiring a lot of detailing and
tinkering to get reasonable performance from. With that said, if you are
really strapped for cash the CG-5 is probably the cheapest mount you
could get away with and has the great documentation located throughout
the web to guide you on the various mods and tweaks. Got cash? Start
with at least a GM-8. It will carry you a long way into this hobby.
For piggy back guiding I have done: unguided, manual through the main
scope and even webcam through the main scope using StarTrack.
Here are some piggy backed shots.

Ditto on George's comments about the books, they are one of the best
places to start along with finding a local resource such an astronomy
club with members into astrophotography. I was actually able to defer
buying my own scanner for a year or more by using a fellow clubmembers.
Good luck,

I think that you are going to find the Min-EQ very frustrating to work
with. Polar aligning will be difficult, the speed of the drive will
probably be dodgey along with the quality of the worm gear.
For that kind of price (IMHO) you would be better off buying a Manfrotto
tripod and head and knocking together a simple type 2 barn door (also
known as a Haig or Scotch mount with isocolese(sp) pivots). That will
give you about five minutes of exposure before errors creep in. After
you have mastered that you will have learned the value of good polar
alignment and the basics of exposure under your sky conditions. From
there you can move up to a type 4 double arm mount which will give you
about 15-20 minutes of exposure (50mm max).
All of the low cost EQ mounts that I have seen need to be stripped down,
cleaned, de-burred, re-greased, and touched up before they can be used.
That being said, you can manage some piggyback guided photos with an
EQ-4 that has been re-worked.
But, get yourself copies of Michael Covington and Robert Reeves books
from Willman-Bell and start your search for a negative/slide scanner.
Then order Jerry Lodriguss's e-book.
Welcome to an obsession we call a hobby...
