Re: GM811G--pier extension or RA extension?
|
I think John pretty much netted it out. ? You could do it either way. The RA extension is quite a bit less, but you have the added benefit of being able to break apart RA and DEC ? The pier extension would give you more clearance, but it would still be a single piece, so maybe better for permanent installs or less travel? ? I just realize I have a 12¡± extension I experimented with but I¡¯m not using, if you¡¯re interested in picking one up used. ? ? Thanks ? Brian ? portfolio https://www.brianvalentephotography.com/ ?

Subject: Re: [Losmandy_users_io] GM811G--pier extension or RA extension? ? I guess the question is how much additional clearance you need/want. The RA extension is only going to give you a couple of inches at best, while a pier extension will give you 8 or 12 inches depending on model.?
In terms of pier extension size I would go with 12" for visual (I'm 6'5) but for AP I would go with the 8" unless there is some other reason for extra height (seeing over the sides of your hypothetical future observatory is a good one :)).
