Not sure how long these have been around, but I just ran across them yesterday for the first time. This is an awesome breakthrough in amateur dobs for the price, IMO. Consider the price of an Orion XT12g against a Celestron CPC 1100. A full inch larger, and nearly half the price.

... or a tracking Dob.

I'd rather have a push-to dob, but it is a good deal for someone looking for go-to. It will be interesting to read some reviews on them to see how well they work. I've had several go-to scopes and I'm generally not a fan. I end up spending more time with the computer than if I'd just starhopped.

Nice - but my next scope will be 16" or more.

Exactly. Tracking is nice but push-to and goto aren't for me.

Spend the money on a good EQ platform.

Well, I'm not saying I'm going to spend the money on one, but this is the first mass produced and fairly inexpensive tracking platform I've seen for a dob. GOTO isn't my bag either, but I vote thumbs up on the tracking, especially considering the "free clutch" full time manual push ability. It's a good product idea, IMO.

Very true- sorry if it came across as if I was ripping on these new dobs. I think it's a great idea. Since it's a system thays incorporated into the design, it should theoretically work better than the "add-on" tracking units like the Track-N-Train for the Meade Lightbridge's. And the clutch is a must-glad to hear that Orion thought about that. :)

Hey, no worries. I agree with all of you. Every scope has it's niche, so it's a worthy idea for many amateurs. I can't tell you how many times I've read and heard from dob owners that they just wish their scopes would track.

I've had scopes with both platform and the on-board GOTO, which I got mainly for the tracking. For my own personal use, I like the on-board system better. Aside from the fact that I once had my old 10" dob fall off its platform when it reached the end of the tracking, with the GOTO there is no having to reset the platform every hour, it's one less piece of equipment to carry around, and it doesn't add 6-8" to the eyepiece height.

That sounds like a poor design if the scope fell off the platform. I would hope that most EQ platforms wouldn't have that issue.

I agree about the ep height though- that's one reason I haven't bought a platform. I'm 6 feet tall so unless my 16" f/4.5 is pointed directly at the zenith (which I generally avoid;Dobson's Hole) I domt need a ladder or stepstool. A platform would change that...

I've seen scopes fall off platforms a couple times in addition to mine. Thankfully that night I was setup on the proper side of the pool for avoiding a fiasco, otherwise I'd have been fishing the 60" long OTA out of the deep end. :boggle: As it was the mirror came out of the cell so I had to remove it to get to the mirror, and got lucky there was no damage to it. In my case I don't think it was a bad design but rather it was an older Tom O. platform and the friction surfaces were finally beginning to wear, so the weight of the scope made it slip past the stop.

The EP height is probably the biggest reason I don't want a platform. Then I'd have to carry a small step in addition so really two extra pieces of equipment to either take to the backyard or pack & haul.
