Quote:Losmandy Titan or something similar at the LEAST.Not even sure the Titan will hold a 20 KG refractor still even though it is rated at 50KG load.Some depends on the length of the refractor you are mounting.If it is much more than a couple of meters long, you will most likely need a steel pier.Titan would likely be your best bet though if you are cost concious.
Money can't buy happiness, but it sure makes living with misery a lot easier!
Quote:We're trying to find out which mount to use to hold a 20 kilograms refractor for a small observatory ( outreach observational use, occasional astro-photography )... without getting under-mounted Losmandy G-11 can hold 35 kgCGE-Pro can hold 45 kg
Quote:sorry, for those who didn't follow the refractor topic, it's about this large achromatic refractor:Fraunhofer achromatic 203 mm / 1800 = f/8.8 (20 kilogram) http://www.apm-telescopes.de/pro_info.php?id=47666&bildid=1651
Quote:"PS I forgot to say I don't want to spend more than $750 on the mount"I love it when they say that

Quote:I spoke to a well known astronomer here in Melbournewho claims he once made his own mount (30 years ago)with a washing machine motor to drive it.He actually got it to track for 5 minute framesusing drift alignment & no guiding

Quote:This mount was recently pointed out to me, not sure how good it is but for what I was looking at it seemed to good to be true. Claims 100lb. instrument capacity. Anyone have comments about this one?http://www.tech2000astronomy.com/nightfire/powertower/Is this good enough to do some light AP as well?

Quote:The Losmandy Titan and CGE Pro are in the same weight class so it's fair to compare them. The Titan is about 20% more but and this is a really big 'but' their reputation for accuracy and reliability is impeccable where Celestron's is not. I use a CGE Pro for my C-14 and, with all of the stuff I have on the mount it's carrying about 80 Lbs. After a careful three star alignment, the mount is capable of keeping a guide star within the FOV of the guide chip on my SBIG camera with the tracking turned off for 20 minutes or so. With the camera guiding the mount I have taken as many as 30 5 minute subframes without finding difficulties registering them.With that said, however, I am VERY uncomfortable recommending that anyone purchase this mount over the Losmandy as Celestron's customer service is non-existent and the quality of their products of late has become very spotty. If I were going to spend $5-6 thousand on a mount again it would not be a CGE Pro.
Quote:Yes I knew the OP was in Europe and given the very poor customer support available from celestron I would not recommend their product for someone who can drive there.I am not familiar with Losmandy dealers outside the US. But I have used a Losmandy mount on my C8 since 1993 with no problems and no complaints. Their mounts are like jewelry, well made and well finished. The difficulty with any mount made in America is the manufacturers are small companies. Even Meade and Celestron, which dominate our domestic market, are too small to maintain repair facilities anywhere but at their main facilities.For that reason alone I would buy the most reliable mout I can find. I also believe you could do much worse than a Losmandy for that price but no better until you get into an Astrophysics mount.
Quote:Good point. I would not pay 9000 Eur for that mount. Ordered From Oceanside it sells for about the same as the CGE Pro or 5995 US (4200 Eur).
