One hour tracking, very accurate, no vibration and slippage: the driving is done by a tangent rod, with an optimised microstep motor and very robust connections: Post Extras:       PierreDesvaux Vendor (Dobsonian Factory) Reged: 11/06/06 Loc: Paris, France Re: THE DOBSON FACTORY; New Travel dob 12" f/d4 [Re: PierreDesvaux]       #5264807 - 06/10/12 02:11 PM Edit   Reply   Quote Quick Reply   Dob with full shroud protection: http://dobsonfactory.blogspot.fr/ Edited by PierreDesvaux (06/10/12 02:12 PM) Post Extras:       suburbanskies sage Reged: 12/18/04 Loc: New Jersey, USA Re: THE DOBSON FACTORY; New Travel dob 12" f/d4 [Re: PierreDesvaux]       #5265355 - 06/10/12 09:15 PM Edit   Reply   Quote Quick Reply   Dear Pierre, Very nice scope and a very pretty backyard! I have a few questions...what is the power source for your equatorial drive? And what type of diffraction spikes are produced by the spider that you produce? Thank you, Mark Post Extras:       PierreDesvaux Vendor (Dobsonian Factory) Reged: 11/06/06 Loc: Paris, France Re: THE DOBSON FACTORY; New Travel dob 12" f/d4 [Re: suburbanskies]       #5268132 - 06/12/12 01:49 PM Edit   Reply   Quote Quick Reply   The backyard needs a little cut... Spring has been very rainy here and grass has grown quickly... The power source for the equatorial drive is a simple 12 V battery. Consumption is less than 1A: http://dobsonfactory.blogspot.fr/2012/05/nouvelle-plateforme-equatoriale.html As for the spikes, they are usual, that is the 4 ones (as far as the branches of the spider are parallel, we get 4 spikes).

I presume these telescopes are not available for customers in the U.S., right?

I would prefer not to have to send my mirror across the Atlantic!

Mark, you are right, it is possible to make the mount without the mirrors and focuser. The only thing we need it the exact focal lentgh and the weight of the mirrors. The same if people prefer to order new mirrors from an american optician.

I really like the clean design of these. Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 7 registered and 7 anonymous users are browsing this forum.
