I really need to eat my "Wheaties." As it is, I've never enjoyed hoisting the 160ED onto my Mach1. And it's not so much the weight per se, as the distribution of the mass along the scope's length. It always feels awkward. Perhaps if I'm forced to mount it more often in my new location (rather than simply roll it out of the garage on some wheels) I'll build up some muscles and soon be twirling it like a baton.
An excellent point. It's sooo nose heavy....
Gee, how nose heavy is it?
It's so nose heavy that as you lift the OTA up into its saddle, the forward weights makes it feel like you're lifting 25 -30 pounds with just one side of your body. Also, you have to spread your arms out so they span past the rings. If the heavy end is on your right hand, this means your left hand is actually pushing the back end up and around the more forward center of gravity of the OTA. You have to then compensate for that with more force from your right arm. That can get to be tiring very quickly, especially early in the morning when you take it apart. I did this with my TMB/APM 175 F8 triplet and it was a bear.
I can compensate for the imbalance to a degree by extending and placing my right hand on the end of the dew shield and lifting that way but I don't like the idea of apply pressure to the nose of the dew shield nose that way.
So for me, the real problem was the high unbalance could just quickly fatigue my right arm. My solution was to add weight.....to the aft end. I found that first configuring the OTA for observing (adding the diagonal, bino-viewer, finder and an aft weight counterpoise to the finder), made for a very balance weight split between my arms and thus a much easier and safer lift of the OTA into the saddle despite the overall increase in weight (about 10 pounds). You can see what I mean by my observing configuration in the photo of my 160 above.
So, despite adding ~ 10 pounds of addition weight, the lift is much easier to do for me. In fact, doing this type of configuring and balancing before the lift allows me, for example, to quickly, easily, and safely lift the ~45 pounds of my old AP 179 F9, up, and into the saddle.
