Hi guys

Does anyone have any data on weights of some common OTAs? I'm looking at an EQ mount for phot with an ED80, and visual with an 8" f/6 Newt... Does anyone know what an ED80 and what a GSO 8" Newt weigh?

Lee,

The ED80 weighs 2.7kg (I just weighed mine for you)

GS 8" weighs 9.5kg (the Dob model OTA)

and don't forget a finderscope! The GS finderscope and bracket weigh 450grms :thumbsup:

An HEQ5 minimum but preferably an EQ6 and better thats if your going to sit them both on top otherwise the HEQ5 is ample.

If you use them together (the 8" & ED80)

GS 8" - 9.5kg
ED80 - 2.7kg
Finder - 450g
--------------
Total - 12.65kg

Plus EP, Camera, tube rings.

You will need a mount that can carry 15kg min.

The HEQ5 Pro has a load capacity of 16kg

Thanks guys for your help. I have my eye on a GM-8 currently, I likely wouldn't mount them together, but use ED80 for imaging on its own (or with a cheap guiding refractor), or Newt for visual.
Didn't think the newt was that heavy...... it is hard to judge weights accurately sometimes especially with bulky things...... :shrug:
