Thanks Craig. I think the ads came out
well too.
As far as which TeleVue, all
the scopes are excellent visual instruments. For astrophotography, the
NP101 is the fastest at f/5.4 vs f/6.9 or f/5.6 with the TV102 and TV85
respectively. With the 102 and 85 you need to get the FF, the NP101 is
already a flat-field instrument so no secondary FF is needed. Note: you
can only do 35mm or CCD imaging with the TeleVue scopes. If price is no
worry, the NP101 is real nice. Here are some shots I took with one last
summer:
For starting out, Jim is correct. Piggyback is the best
way to get started. If you don't have a equatorial wedge, your exposures
times are going to have to be fairly short to maintain round stars.
Obviously the shorter the lens, the longer you can expose without
trailing. I don't know the exact times for specific lenses but I'm sure
Mike Covington's book has it listed.
Have fun!

Chris:
I am sure you get tired of people mentioning...hee-hee, but good work on the
televue add. I am highly interested in a televue, but don't know just which
to go for. I love the portability of the tv85, but saw the np101 at
star party, and would love to look through a 102. Any suggestions for
the future?
By the way,
currently as mentioned before, I am limited to an lx200. Jim Janusz,
recommended that I start with some piggyback work and then progress.
But since I do not have access to a wedge, I am wondering how long of
exposure I could get due to induced alt-az field rotation. Any
thoughts?
Thanks for
the warm welcome,
Craig
Welcome Craig!
Jerry Lodriguss has some very good info on getting
started in AP on his website. www.astropix.com

Hello
all:
I have recently
joined the APML at the recommendation of Jim Janusz. My Name
is Craig Watson, and currently live with my wife and three young
daughters in Southern Texas. I am a newcomer to astronomy,
having only been truly interested for the past 2-3 years. I
became intrigued with astronomy and astrophotography after having
been to the Texas Star Party this past year. I was so amazed
to meet and talk with people like George Kepple, Glen Sanner, Al
Nagler, Stephen O'meara, and others. I was so
encouraged by the wealth of help and encouragement I got from
them and many other seasoned veterans. I currently only have
access to my Uncle's 10" LX200 (without wedge, I know not the
optimal starting point) but am making plans over the next couple of
years to acquire a televue refractor and a suitable mount.
I would like to
thank you in advance for accepting a greenhorn rookie into the
group. I imagine that I will be mostly quiet, reading and
learning in the beginning, but I would still ask for any insight
that you could give to an eager, budding young
astrophotographer.
Should you have any
pointer on where and how to begin they would be incredibly
welcome.
Kindest
Regards,
Craig
