Hi George,
?
I don't know, I didn't weigh the whole kit and caboodle.? But piecing it together I suppose it is about 70 lbs. ++? based on what I have notes for below.? It tracked well though I never really got an actual PA and the moon remained on the ASI2600MC-Pro sensor ROI all night.? It was not being guided and I never bothered with shooting any alignment stars.? Just got lucky as I just used the usual marked spots in the driveway and didn't touch the ALT / AZ adjusters on the G11G.??
?
I know this old LX200 Classic 10" f/6.3 buck naked before even a dovetail or visual? back is added weighs in @ 27+ lbs.? Add the 2.5" Moonlite focuser, old fashioned un-lightened 17" double Losmandy D dovetails and radius blocks, Stellarvue 50mm finder and mount, 2" AP Maxbight diagonal and 35mm Panoptic and it's probably over 42 lbs. or so which is what I have old notes for.??
?
Then add the Askar FRA500 with rings and Losmandy DUP14 and top ultralight V-dovetail weights 15 lbs.? Add to that a Deep Sky Dad Flat Panel, a pair of Stellarvue 50mm optics, a guidescope with the helical focuser and ASI678MM and the finder with RACI prism diagonal eyepiece and mount, as well as an ASIAIR Plus v.3, ZWO EAF, ZWO EFW, ASI2600MC-Pro and various associated Baader M68 extension tubes and adapters to support the Askar f/3.9 reducer.? This rest add maybe 10 lbs??
?
And all of this gear is sitting on an original Losmandy Side-By-Side mount with the addition of an ADM MAX ALT/AZ Aiming device.? This configuration weighs a little over 7 pounds.??
?
To really balance it right takes the practical max.? 91 lb combination of counterweights. I tried using a pair of 11 lb. CWs but this left me no shaft room to adjust balance easily.? This is all that.really fits on the CW shaft with an easy to move 7 lb counterweight used as a balance adjuster.? But I couldn't take my last 21 lb. CW off the GM8G which had a load in the saddle that used the 21 lb. and a pair of 11 lb. CWs.? ?
