As you say, $300 telescope. Adding a $330 coma corrector just seems wrong But of course it’s transferrable to any upgrades I make, just kind of hard when starting as all the extras are turning out to be triple the price of the scope itself.

Is a 3mm spacer enough to cope if you starting adding extras such as an oag though? Or does. 3mm spacer give you more than 3mm back focus distance? I’m concerned somewhere down the track it’ll hit that back focus wall again.

I’m also still trying to see if I can fit an 8” onto the HEQ5. I know 10kg is the recommended max. I’ve got what I think are all of the extras and the f5 8” total at about 10.5kg at the moment.

If it wasn’t for all the recommendations against it, the f4 would come in at about 10kg. Apparently somewhere once there was even a carbon fibre version, which would have weighed even less, but it seems to be not available currently.
