Discmount Extension... DM6 / DM4
Posted 30 April 2013 - 08:23 AM
Has anyone used the 8" Discmount tripod extension on their DM6 or DM4? How do you like it? Is it stable? Still stable with a strong breeze? Have you found it necessary for getting the scope to the zenith? If anyone opted for the tall Discmount tripod instead of the standard tripod with the extension, why did you choose it and how has it worked out?

I am curious about the AP extension. How does it mate to the Rob Miller Tri36M? Do you have the part number of the AP extension?

I also used a Meade field tripod/Losmandy MA adapter and Losmandy 12" extension rig which had more clearance at zenith but was much heavier.
Depending on the weight of the scope (maybe up to 20 lbs) the standard DM6 tripod and 8" extension would probably be ideal, above that weight, I would recommend a Losmandy HD tripod/w Losmandy 12" extension for best results.

This is 6" f/8 refractor with DM-6/12" extension on FHD. It barely clears zenith.
When I really want to clear zenith, I add DM-6 extension, total 20" extension.
Both 12" and 20" extension setups are very steady and *HEAVY*.
Clearing zenith is a nice to have than a must have, IMHO.
By the way, here is weight info:
2.301 Kg: DM-6 extension
1.410 Kg: DM-4 extension
1.072 Kg: DM-6 G11 adapter
2.815 Kg: G11 12" extension

The bars in the extension are helpful as a handle. The extension does make it easier to look higher in the sky, but is not essential. Mostly, it raises the eyepiece when you are working high in the sky. If needed, you can reposition the SkyCommander if it gets too high.
Hope this helps,

A very short OTA might work well without the extension, but with a longer scope like my TV 102, it's an essential accessory.

Plenty stable for my MN-66
Angled handle still hits tripod legs near zenith, but can be removed or worked around.
