The red cast seems to come from the UHCS filter and that the camera is moded. Sky was heavily light polluted as well
This is a low profile focuser for scopes with limited backfocus, for conventional scopes the normal profile one would be the go. I would handle heavier loads as the bearings that guide the 2 inch shaft are further apart, with mine they are very close together, if I push down on it with the camera on I can see some movement. On its own, my 350D is light enough that it does not move, but I think a cooled one like Houghys might be too heavy. Scott
