Quote:Above we have estimates of 33, 50 and 75% of rated capacity for imaging.I think they're all far, far too precise. The rule of thumb I'd use is that as you get closer and closer to the rated capacity expect more and more trouble with tracking. But each mount (I mean every individual mount, not just make) will be different. There are people using CG5s with a fair amount of weight on them and 10 minute subs. I wouldn't bet heavily on that, but it can be done.

Quote:Better signal-noise ratios with longer subs. But the thing is.. I live in yellow skies. I can just make out the milky way on the clearest of nights. So even with an LP filter would 20 minute subs even be worth it in such polluted skies?
Quote:Well for starters im just going to be using a a 2 inch LP filter for my Canon EoS Rebel. Not the best camera, but it could be alot better with the right hardware. Right now on my Cpc1100 i can do 2 minute guided subs if im lucky. And on top of that the vignetting is horrendous. Its time for me to get serious. I want a telescope/mount setup i can walk away from with confidence. I want something that will just WORK. And work WELL. So far my AP adventure is consisting of nothing, but trial and error... with alot more error then trial. Idk its a tough call. If im moving up my price range into $6k for mounts then alot of doors open up choice wise. The Mach1GTO does seem really nice. Im just deterred by the amount of needed accessories and switching over to new software. ( Ive become very attuned to NexStar ) But i am confused. .. This GTO mount is $6,415. Yet it can only hold 45lbs of equipment? Yet the Losmandy Titan can hold up to 100lbs for $400 less... so what going on here? Is the GTO THAT much better at tracking? Sadly im not to savy with EQ mounts having never owned one. But i do understand them. Its just alot of these "features" are almost off-putting. As far as narrowband imaging goes... i dont have much ( if any ) interest in it. ( Although i said that about AP when i first bought my CPC1100 for visual use ) Ive also been considering a CCD camera, but... no. I want to stick with DSLR's. There just... easier. And cheaper.
Quote:- a tripod; Rob Miller makes some fantastic ones starting at $575; 200lb capacity and weighs 9lb; IMHO this is the best buy as the AP tripods start at $700+ and weigh more
- an ADATRI (flange to attach the Mach1 to the tripod); $60
- a dovetail saddle; Robin Casady makes good ones, better than the AP ones IMHO since I have both an AP saddle and a Casady; about $150-ish

Quote:Google can point to all the information needed
Quote: i imagine an APO with just as much focal length as my C11 will cost just as much as this Mach1 if not more.
