Not really classic, but please wait ....

The 2000 bug

DS series
"The most important advancement in beginning and intermediate telescopes in 100 years."

For many, the DS telescopes are beginner telescopes (in best case) or even toy scopes cheaply made.
For me, these are great telescopes.
They are very lightweight, compact and easy to set up, so I use them very often.

First one, the Meade DS70-EC
This is my third DS70 telescopes and this one delivers pinpoint star images and perfect star test.
Chromatic aberration is very low at f10.
It is lightweight and could be a great grab and go telescope if the ota could be removed from the mount..
This is the main drawback.



Despite being made in Tawain or China, these telescopes are entirely designed by Meade, you will never find the same telescope with another brandname (like the AR5 or AR6 refractors).

The pictures shows some modifications I have made on my telescope :
DS90 larger tripod
#1240 electronic focuser,
Meade metal focuser tube and aluminium knobs (from the RG telescopes !),
Meade 390 metal finder bracket and 6x30mm finder (instead of the useless plastic 5x24mm).
The OTA has been to go back due to the increase weight.

DS90-EC
The DS90 was made in Taiwan by the company wich manufactured the 390/395 refractors.
The optics were the same, but in order to reduce the price (due to the expensive goto technology), Meade used plastic for the focuser and the finder bracket.
Even the chromed draw tube focuser is made with plastic, but unile its predecessor, it can accept 2" eyepieces.

With a focal ratio of 11.1, this is one of the last long focus achromat refractor.
The DS90 is probably one of the best and powerful DS telescope (with the DSX125) that Meade has ever made.
The optics delivers very good images and the OTA is the maximum load that the DS mount can handle with ease.

The OTA is shown here with 390 rings which allows me to use it on a gem mount.
These rings are also used as counterweights when the OTA is put on its DS mount.

The finder and metal finder brackets come also from a 390 refractor.

DS-2102 AT
With a 102mm objective (focal lens 800mm), the DS2102 is the biggest DS refractor that Meade ever made.
It wasn't a regular model and therefore didn't appear in the Meade catalog. It was made to be sold in some shops like Costo or Wallmar.
A few models has also been sold in England and can be regularly found in the used market.
The DS2102 was fully equiped :
- two "premium" eyepieces : the Meade Series 4000 SP26mm and 9.7mm,
- the #497 autostar.
It is now discontinued.

This telescope gives very beautiful views with pinpoint stars, few chromatic aberrations despite its short focal lens (a 102mm lens should have at least a 1300mm of focla length).

The Meade #883 deluxe tripod (Taiwan), with no plastic parts, offers the right stability for the DS2000 mount.

I have added a DS LNT module for automatic alignement, a Meade 6x30 finder to replace the small red dot finder and a #1240 electric focuser.
The #1240 has to be operated by an hand controller because the only aux port is already used by the LNT module.

As always, the Meade RG aluminium knobs have replaced the original plastic ones

The big lens : 102mm of glass in a plastic cell.
No way to collimate the objective, this is a beginner telescope.

The black focuser tube has been replaced by a standard DS focuser tube because the internal baffles restricted the field of view when using 2" eyepieces.

DS2130 ATS
After I bought the DS2114 telescope, I was so pleased with it, that I wanted its bigger brother the DS2130.
At that time Meade didn't sold this telescope in Europe and I had to find a used one.

The one I bought from US could have scared many buyers but not me.

I center marked the mirror as collimation is critical with a such fast mirror.


I bought a new frocuser with its relay lens from Meade.
I bought several NOS Meade DS2130 (long tube) mounts because I knew that the craddle ring was the same as the ATS one.
I added a #1240 electric focuser with the Electronic Controller hand paddle. The only aux port is used by the LNT module.

I added a beautiful all metal vintage 6x30mm Meade finder.
The DS finder base is now fitted with a first generation DS LNT module instead of the plastic 6x30 finder.
The LNT glass is not present because it is very fragile, so I prefer to remove it when I store the telescope.

This is the "Atomic Time Module" which gives accurate time for the Autostar controller (in US only ...).

Fun thread.

I have a DS 70 that was my introduction to astronomy a couple of years ago. It was found rather abused at a garage sale, but the objective was in good shape, despite having been disassembled and reassembled incorrectly.... A fun little 'scope that I kept and have given to my Son, along with a set of Surplus Shed Kellners, so he has a full setup he can call his own. It all works suprisingly well, and he let's me borrow it from time to time ;)

And now the ETX line
"When the original ETX telescope was introduced in 1996, it quickly created a revolution in amateur astronomy. Here for the first time was a stunningly beautiful, ultraportable, and highly versatile telescope system of unprecedented optical resolution and performance.
Within one year of its introduction the ETX became the largest-selling modern telescope in the world."

ETX70-EC
Few people know the (now discontinued) ETX70EC model which was prior to the ETX 70 AT model.
The ETX70EC used the same base as the ETX90 offering 2 aux ports and the 12V connector.
The OTA color is black rather than the deep blue of the AT model.
The OTA can be removed from the fork mount and used as a guide scope.

Why did Meade used black color for the ETX EC ?

The right angle finder, made in Japan, was made for the 2045 telescopes, it is mounted on a #827 finder bracket.

I made a weight using aluminium filled with lead for a perfect balancing, I can now use the ETX manually with all the brakes relaxed.
The rear accessory port cover, made in aluminium, comes from an ETX maksutov (the original one is made in plastic).

And now the ETX125 AT

Here my ETX125 telescope.
It has the UHTC coatings and it is one of the latest Meade ETX made in the USA.
I bought it new and I have used it only once, it is fully loaded with all Meade ETX accessories : electric focuser, dewshield, T adapter, hard case, 12V power cord....
It is stored and will became a real collector.

I choosed an ETX-PE hard case because it is more beautiful than the older black one and mainly because its square shape allows to store the telescope vertically with the meniscus corrector close to the ground.
This position reduces the risk that the glued bafle fall on the primary mirror by gravity.
I recommend for the same reason to store your ETX in a controlled temperature area (and not inside a closed car in summer...).
