Is anyone familiar with equatorial platforms for Dobs? This company at http://www.eqplatforms.com/ has a fairly inexpensive model. Is it any good?

I'm new to astronomy and have not yet purchased my first scope. As I ponder what size Dods and what make to purchase, I am also thinking of what options may make viewing more enjoyable as I get more involved over the spring and summer.

I do not know much about these mounts. Can anyone share with their experience on this subject?

If I had the money I would just go out and buy a nice truss Dobsonian with a nice EQ platform as my first scope, but don't we all! :crazy:

Mike,
I have a AstroSystems platform for my 13" TScope, it is basiclly the same platform as the eqplatforms. I really like it a lot.

Although I didn't always think so, especially with the use of widefield eyepieces, I now consider an equatorial platform to be a necessity for critical observing with my Dob.

Mine was made by Red Oak Astronomy, and you can see it here:

Hi Mike,
Next time you come over, I'll have to set up my Johnsonian tracking platform so you can see how they perform. Mine is a Type II which is now discontinued. It will track for about 50 minutes before needing to be reset. Made from aluminium. Light and strong.

I know this isn't a lot of help, but I do know that certain companies on that list make plarforms for other companies on that list, but don't remember specifics...

IE - that's more of a list of folks who sell them than a list of folks who manufacture them.

<sorry>

That used to be true... :)
Debrito (Affordable EQ Platforms) used to make them for Astrosystems, but not anymore. In fact, Astrosystems now supplies parts to EQ. The only one on the list who does not manufacture their own is Night Sky.

Is the eqplatform a more practical solution than switching to an eq mount from a $$$ standpoint? I would be buying as I am not a DIY'er

Not planning on this anytime soon but keeping the knowledge stored away for future reference. (Like I will ever find it again in the clutter of my grey matter)

Thanks for the links and all the comments!

I had a chance to see a Johnsonian in action last night. Unfortunately there was a mechanical problem so it was only working for a short time.

The Servocat GOTO at Night Sky Scopes is very interesting! I might have add one of these to my wish list!

Probably not, for an 8". At 14" the platforms make a lot of sense compared to an german EQ mount. Somewhere in between is probably the line. If field rotation isn't a concern there are other options, such as ServoCat, the Bartels systems, or the Dob Driver.

"I had a chance to see a Johnsonian in action last night. Unfortunately there was a mechanical problem so it was only working for a short time."

One of the motors wasn't working. The next morning after switching connectors back and forth, it started working again. I think there was a corrosion problem. The platform had been sitting for a while. We had fun with it anyway in manual mode. I got to try out Mike's Oberwerk 20x80 LWs on one of my P-mounts and they were really nice to look through. I'm definitely going to spring for some 22x100s in the near future.

Greetings Craig!

I'm glad we got a chance to view the planets Saturday night :yay: The views of Saturn were spectacular! With the pending weather this evening (snow and freezing rain) and again on Thursday/Friday, this week is not looking too good.

My Bogen tripod arrived this evening. Now I'm waiting on my "L" bracket and my unimount.

I feel that I have made sound decisions on my choices of Binos, tripod and the unimount. I have you, EdZ and the others here at cloudy nights to thank. :bow:
