Interesting. Tonight after work, I'll investigate further. I only had a change to check the rings on the tube last night briefly.
They do feel like a tight fit; but Id rather it be a tight fit then having freeplay where the tube might slip, just as long as it doesnt buckle the tube in the process.
Anyone in Perth with 235mm rings that are no longer needed?
Might have to make an order from AstroShop with the piggyback mounting on the rings. Rings I got are from bintel which dont have this.
Cheers
