deanchapman2705 Posted January 11, 2022 Share Posted January 11, 2022 Hi, I just want to clarify something before buying my next mount (iOptron GEM28). https://www.ioptron.com/product-p/g281b1.htm On iOptron's website, it states the max payload of the GEM28 is "28 lbs (12.7kg), exclude counterweight". So I'm guessing that with it's 4.5kg counterweight attached, the max payload is then 8.2kg? So for my soon to be 6kg setup (scope, camera, guider etc) this will be ok. I then came across a forum on Cloudy Nights reviewing this mount... They say their setup weighs a total of "9kg. Which is 70% of max payload". He also has two 4.5kg weights (9kg). So would it not be a case of a total weight of 18kg on the mount (5.3kg over the max payload)? Or am I wrong to include the counterweights in the total weight? I currently have an iOptron Skyguider Pro with a max payload of 5kg. My current setup comes to 3.7kg (excluding counterweight) the counterweight weighs 1.35kg which together adds up to just over 5kg. I know it definitely can't take more as it struggles with exposures over 2mins (guided) which makes sense. But to say it could take 1.35kg more seems crazy. Not sure if this is different with a star tracker though so though I'd check with everyone else. Any help would be much appreciated!
