Compare these two equatorial Mounts.?
I will be continually posting questions I have, as I am looking to buy an equatorial mount for my 'scope. The optical tube weighs 30.8 lbs. I will be using it to keep the objects in view and do some broadcasts of my views online. I don't need it to be like an Astrophysics mount lol. The longest exposures I would possibly do are only several seconds to two minutes (probably not even). I just want to delve into doing broadcasts, even if they suck lol.
Just looking to compare these two. I'm wondering why the Celestron is much cheaper and is able to carry 5 extra pounds. Any advice is much appreciated.

Celestron CG-5
The focal length is 1200mm and the focal ratio is f/4.7. If that helps.

Both of these mounts should be adequate for your application, which limits your exposures to 2 minutes or less. An optical tube weighing 30.8 pounds is fairly large as telescopes go. If it's a longer focal length, say f8 or more, you might find these mounts aren't stable enough.
The rated weight capability of a mount can vary quite a bit. Some manufacturers tend to overrate their equipment, others underrate it. As a general rule of thumb, visual applications are less demanding than imaging & the longer the focal length of your telescope, the more weight capability is needed. Don't forget to add in the weight of any eyepieces, finderscopes, cameras, etc.

I have heard good things about the CG-5, but I have no personal experience. Given the much lower price, I can't see not trying it. I expect you could return it if really dissatisfied.
