Question about Celestron Optics

2 Answers

N00b looking for help with Celestron 4 1/2

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. for camera adapters. HTH, Geo.

New out of the box, our Celestron Nexstar 4se does not ask for our location. Cannot find it anywhere in the controls to input, therefore it will not align.

RESET the hand controller-- then turn it off-- wait 15 seconds and turn it back on. If this does not fix it the firmware will need to be reloaded. You will need a special cable from Celestron to update the firmware.

I would simply return the scope and get another one-- if the scope is new.

Ht 3000 key pad not working

Check to make sure you do not have a bad cable. Order a new cable and try it. If it still will not light up -- try to locate another hand controller and see if that works.

If none of the above works the scope will need to be sent in to Celestron for repair.

I have a CPC11GPS telescope that was working the last time I used it, which was 6 months ago. It is in NEW NEW condition. I pulled it out last night, turned it on, allowed the system to align itself using...

The clutch is not engaging in RA. Maybe the gears are not actually meshing together? A loose worm gear?

You can open it up and look and see if anything obvious is loose. Otherwise it's a trip back to Celestron.

The C8 optical tube has a very large focal range. It should be capable of focusing on objects from 15' to infinity. To focus on object at infinity you have to move the primary mirror foward. You do this by rotating the focus knob CCW. Rotate the knob CCW until it comes toa stop them slowly bring the mirror back by rotating the knob CW while viewing the object. It will snap to focus so don't move too fast yor you'll miss it.
