Anybody know anything about these ?

A 4" ( DS-90EC or DS-114EC ?? ) has shown up on the local auction site with the electronic Autostar control etc. Focusser rack apparently has a little damage to a few teeth but I am more interested as what the optics are like. It's quite an old model I gather, late 90's maybe. There is very little on the Meade site and although I found the manual other htan aperture it doesn't give much on the specifications.

A longish focal length 4' refractor looks like a nice option if the optics are reasonable. I am not expecting APO quality but a good Achromatic would be useful.

No knowledge of it over here ?
Reply on Cloudy Nights gives the optics a good rating. Worth a punt, we'll see how the bidding goes.

Hi

Are you refering to the DS 2000 series of "Department store" telescopes with autostar 494 controllers. There was a DS2070 refractor and I think later a DS2080 70mm and 80mm refractors. The DS2114 and DS 2130 were reflectors. They were released around 2001. The rack focusers were rather flimsy on the refractors.

I have a DS2080 that gives reasonable views and is a goto telescope. I gave it to my grand daughter (8) who thinks it is great and she is looking forward to setting it up at Wiruna this weekend.
I bought it new for $200 as an end of series sale.

Hi Barry,
Interestingly enough the person selling the scope has described it as a reflector but posted several pictures of a refractor. They are actual pictures taken at a home, not just copied advert or brochure pictures. The rest of the sale details indicates someone without much telescope knowledge. I shall go and ask for clarification.

The model numbers I posted, DS-90EC & DS114EC, are from an astro shop in USA second hand listings pictures and description and I got some info from Cloudy Nights from someone who has the manual AZ version, no control.

I think your DS20xx models are a later model as they are still listed at the Meade website. From what I understand this model series dates back to late 90's.

I am actually not bothered with the electronics, it's the optics I am interested in.

Here's a few pix from the listing ...

The photo looks like the early release of the DS2080 refractor. It has the black single arm mount and the older tripod. The later DS2080 I have has a silver mount (like the Meade picture) and the later tripod that is a bit better than the older type that broke fairly easily.

The optics are OK for general use but the rack focuser leaves a bit to be desired. We have used it mainly at astronomy nights tracking the moon Saturn or Jupiter. This usually impresses the non astronomical viewers.

I have some early catalogues.It is in the 2002 catalogue but not the 1998. I don't think the autostar mount was released until 2001 so I don't think it would be any earlier than this. The ETX 60/70 came out about the same time.

Mike Weasner's site might give some more informarion.

I took one of these DS mounts apart and used it to turn my ETX 90 RA into go-to. The goto with DS motors is nothing special, even when trained. But it will put you in the general direction. I have spare DS motors and pieces if you're interest... good to have backups.

I did the same with an ETX70 OTA on a DS mount that had been dropped and broke the flimsy Dec bearing clutch assembly. I made a new one on the lathe. It does not work very well on the batteries. Tends to get "stalled motors" but works great on 12v. It works great as a goto because of the short focal length of the ETX70 and tracks well.

Barry, nothing useful on Mike Weasners site re DS Series but thanks for the link, quite a bit of other handy stuff to read through.

Cheers
