EQ mount for the Low latitudes?
Posted 06 February 2011 - 01:08 PM
Is there any solution I can do to take long exposure ,guided astrophotography using a Eq Mount?
I do know the HD pro wedge can be use for low latitudes. I'm just wondering if there's a mount. It's self

The Advanced Series CG5 is supposedly capable of also going to an lower altitude, but for that you will need to unattach the plate where the front latitude screw goes through, since if not the front motor housing will hit the screw. Changing the legs length as I described before will yield the same results as above (and risks). Of course, to clear tripod leg you will also need the pier extension (the same SVP one will work also for the CG5). In fact, it works for the Orion's Astro View, Sky View Pro, Sirius EQ-G, and Celestron's CG4 and CG5, and who know which ones also from other brands.
I do not know if there is a EQ mount with the ability of going to such low latitudes without any modifications (I guess the manufacturers do not like us tropical people ), but I think that with a combination of the remedies I stated above, I bet you will solve your problem.

I live in Singapore.
The usual method is to get a vixen sphinx or GP-D / GP-D2 and buy the vixen half-pier.
I went cheap and just got the Orion SkyViewPro 16" pier for my GP. works fine. These will work without any problems, the vixen mounts go to zero latitude. the pier is to prevent the counterweights from hitting the tripod legs.
if you get a pier mount (like the Antares pier) instead of a tripod.. then you don't need the half-pier at all. This is good because the vixen half pier goes for $200.
If your budget is more into Takahashi territory, make sure to order the one for low latitudes (0 degree to 50 degree).
