The 8” Newt is definitely a wind sock and on the HEQ5 a gentle breeze makes the guiding jump around a bit. Perhaps another good reason to go for a more compact refractor, particularly if you image in lots of different locations? When I head out of town to a dark site (in my smallish car) I usual take an ED80 refractor for this reason - just not sure what the wind will do and it sits great on the HEQ5. The backyard I can experiment a bit more. I wonder what impact the observatories Diego builds has on the efficiency of imaging with his Newt?
