Question about Celestron Optics
My father received the above mentioned telescope from my mother for a birthday gift 15 yrs ago. the development of the Northern VA-Dulles area (where they live) has made it so that he has to travel more than an hour to get out of the light pollution. i moved to Maine 5 yrs ago and now have a little girl who is obsessed with the moon. dad brought the telescope and tripod up this past father's day weekend but no longer has any of the manuals and hasn't used the telescope in 5 yrs (so he's forgotten most of what he learned).
i am on the boarder of ME and NH near Portsmouth, NH. there's a shop in Plaistow, NH (about and hour away) that offers instruction and a local astronomy club that may be of help but i'd like to try using this asap. there's 3 eyepieces- a 10mm SMA (i don't know what SMA means), a 25mm SMA and a "Deluxe Baffled 2x Barlow". there's also a collimation tool (to calibrate the mirror, correct?).
dad mentioned that there is a need to align the tripod so that you can properly track (manual adjustment, not power) objects but he couldn't remember how to do this.
i thought he had a lunar filter, but i don't see one (perhaps i don't know what i'm looking for either).
and one last thing- i'm a pretty serious photographer and i would love to do some astrophotography. i have t-rings for both my Pentax and my Canon SLR bodies, so it looks like i will need a t-adapter. any hints/tips in this area would be great, too.
thanks in advance for any guidance provided
Thanks very much! it looks like it's a FirstScope 114 with a wooden tripod (it doesn't have the C4.5 markings on the tube). this gets me headed in the right direction. too bad it's going to be cloudy/rainy all weekend :-(

Celestron has sold a few different 4.5" Newtonians. The finest was the C4.5 by Vixen of Japan. the manual is here:
The FirstScope 114 is another and the manual is here:
SMA is for symetrical modified achromate. A Kellner eyepiece design. This is an inexpensive eyepiece, but not a bad one. A lunar filter is basically a sunglass lens for the eyepiece to cut down on the moon's brightness. ScopeStuff.com for camera adapters. HTH, Geo.
