Mark (mgwhittle) if you don't mind, I had a question... have you used it to support your AP175? If so, is it fine with it, damping time and support-wise? And, I have read that it is possible to buy a larger tripod shelf/spreader for the Planet from Berlebach, so that the legs spread a little wider and thus offer more support, have you considered that that might be necessary? (I ask because I'll be getting a larger refractor, so I'm wondering... to be honest I'm also wondering how you feel about the AP175, but that's outside the scope of this thread! But: good?)
Quote:I love that picture with the cat.
Quote:Mark I'm a fan o' natural finish but that nutwood brown is beautiful looking!
Quote:However, I would not put the 175 on it because the moment arm of that scope is significant and I don't think the Planet is up to the task because of the leg spread. It's not wide enough IMO to handle that weight slung out so far.
Quote:You don't need to buy a larger tray, you can move the standard tray up a bit and drill new mounting holes.
My little Agatha. You left too soon. My furry friends, past and present, are always with me.

Quote:The larger tray should not require any drilling and would widen the stance of the tripod.
Quote: I looked through the Berlebach catalog but they don't list the tripod spreads anywhere. However, they can be used with a chain system like a surveyor's tripod rather than a tray which would then allow for a much wider spread.
Quote:Mark, don't mind at all, in fact this sort of information is desired. Beautiful bino setup 'action pic' there. Which scope is that?
Quote:Actually, the TEC 180 might be just fine on it. The AP 175 is longer and significantly heavier.
Quote:Which Berlebach you would choose a notch below the Planet tripod ?What source for purchase ? Direct ?
Quote:Berlebach did not recommend to replace the spreader with a clip-on tray on their high capacity tripods to increase the leg angle. The logic was that for a heavily loaded tripod with a wide leg angle on a slippery surface (I requested plastic feet instead of spikes) an accident like inadvertedly kicking up the tray so that a clip releases might lead to a leg swinging out and the tripod falling over.
Logical, but I guess it could be prevented with a safety chain.
Instead they suggested that they supply a tripod with the spreader installed without the screws in place, whereby I could choose and adjust the leg angle (by varying the spreader assembly height on the legs) until I'm happy with it, and then finally lock the spreader with the screws.
Quote:Make sure that you can still install the tray at the desired location before piloting new holes for the spreader brackets.
Quote:I created my own tray because I wanted one with a lot of 2 inch eyepiece holes and immune to damage. I moved up the brackets because I didn't think that the legs were spread out far enough when in the lowest position with my 12 inch Losmandy pier extension. I only keep the legs in the shortest position when doing outreach to elementary schools. When observing with only adults I like the tripod much higher. The pier extension allows my TEC 140 to rotate clear of the tripod legs when looking at the zenith.
