| p.17 #8 · Nightscapes using AstroTrac Tracking Mount |
Sorry, I'm bringing this thread back up.
I recently picked up a astrotrac and wedge, I'm in the process of doing some modifications on it, but I'm going to try and get some shooting with it done during the the next few new moons. I've done some AP with larger EQ mount setups but their size, weight and bulk made them really really impractical and to take into the field for use. but I'm pretty excited about the astrotrac, it's size and weight should be really nice. and with my current gear and a few pieces I've been able to cobble together, it should be a nice solid stable setup.
I'm still combing through the posts, but has anyone used the TH3010 head with it? any thoughts or info on it? being able to balance the scope/lens with independent planes of movement would be really nice, similar to a GEM, much better than a ball head, or even a gimbal. I thought about building my own version of it to save some money, but the fabrication time and cost wouldn't end up being too different so I may just end up grabbing a real th3010 in the end if it comes to that.
The only issue I worry about is it's weight limit, the TH3010 spec'd for "about 20lbs" weight limit. I'm wondering if that is fairly conservative or not...If I did get a H3010, it would be the weakest point (at least according to weight limit specs) in my setup by quite a long ways (astrotrac is spec'd for 35lbs, wedge is also 35 lbs, my leveling head is spec'd for 100+ lbs, legs are 88lb)...I do have some fairly heavy setups I would like to use with the astrotrac, the heaviest of which is a small 6" RC reflector scope with a D800E mounted to it prime focus (scope is ~12lbs, camera body is roughly 2lbs, a few accessories, cabling, plates, etc, and I'm already at 15+ lbs payload) I typically like to keep the weight limit of my support equipment at least 2x the weight of my heaviest setup, so the only part that doesn't fit in that would be the TH3010...hmm...I have more research to do, but any thoughts are appreciated.
