Hi peoples,
My grandfather passed about a year ago and some of my inheritance was a questar telescope. I have used it to gaze at the stars and seen the rings of Saturn but I know I am not using it to its full potential. The more I read about how good these telescopes can be the more nervous I am having it in my hands.

Any ways, its a questar 3.5" telescope with the leather case , keys are still in original bag, power cord, legs, solar filter, both a 24mm, 16mm lens. The etching on the back, #3-cv-dp-5623-bb, has turned up that it is a duplex model with broad band coating.
here are some pics of the questar. any further information anyone can hook me up with, it would be really really awesome.

You have a 3-CV-DP-5623-BB

3 = the last digit of the year it was made (1973 for yours)

CV = Cer-Vit (the material the mirror is made of, CV was an upgrade from the Pyrex base mirror and is a good thing)

DP = Duplex Model (this is a major upgrade from the base Standard Model and allows the OTA to be removed from the base and used on a standard tripod, this is a very good thing).

5623 = This is the real serial number and means the Q3.5 was made in the 1970s (SN #4000 to SN #7500 were made in the 1970s). The 3 at the begining of yours means 1973 was the year of production.

BB = Broad Band Coatings on your CV mirror, this is a good upgrade from no coatings.

You own a very nice Questar 3.5 inch mirror Duplex with an upgraded mirror.

How much it is valued at is a broad spread of factors.

Some recent sales are:

AMart website (these are asking prices of duplex Q 3.5s)

year not known $2450 not a CV but has PGII

year not known $2300 not CV

1968 $2500 not CV

2007 $3995

1994 $2450 Zerodur mirror (like a CV)


1989 sold for $3176.25 Zerodur mirror plus 5 EPs (the extra 3 EPs are probably worth $600)

What yours is worth would be in the $2000 to $3000 depending on it's condition. One note: even if it is worth $3000 it is ment to be used and is a very well made and can handle the task.

Good luck, Bill

thanks so much Bill. This thing has very little scuffs on the unit, as for the mirrors they are very clean. I think he had it in storage for at least 20 years. I just don't have the time and money to invest in making this a full hobby as much as I would like. I also don't wanna be responsible if I break it doing some thing stupid. I am a very clumbsy person.
