Hi Narayan,
I have an obsy now, but previously used a telegizmo cover.
I live in the tropics (Darwin), where it’s hot, humid, wet and cyclonic! I had my c925, azeq6, on a tripod then pier...for several years! (I’m not kidding). Only finally had an issue when the cover sprang a leak at the seams. Caused a bit of bother with water getting into the tube and causing some corrosion, was easily fixed though.
Would I do it again? Absolutely, for not having to setup and tear down. I might check on the seams though more frequently and maybe replace cover every 2 years or so.
First light optics was the most economical way of acquiring one, in my research.
But as always YMMV
