CEM26 Diet
Friday, 29 July 2022  | 

I needed a smaller counter weight for my CEM26, the supplied 4.7Kg was just to heavy.
Why so much for a lump of iron? Well the machining of the locking screw is first rate, with a brass clamping bush so as not to damage the counter weight bar.
FLO delivery and packaging 1st rate.

Ideal for the smaller scope

Following recent purchase of Ioptron GEM 28 I found that the stock counter weight was just too much for the small evo guide 50 ED. This is ideal. Prompt dispatch also following easy purchase process. Thank you FLO

What can I say

It's a counterweight. It was heavy, but not as heavy as some.... I mean it's a weight, so I guess you expect that. It has a hole in it, like a doughnut, but don't try to eat it. I now need to see a dentist!!

In all seriousness, it does the job, original item, no complaints - now I can view the universe.

iOptron 2kg Counterweight for iEQ30 / MT / AZ Pro / ZEQ25 / CEM25

I use an extension bar including this 2kg weight for my CEM25P mount and it helped me achieve balance with a large Bresser Messier AR-127L telescope (8kg).
