Hi there every body I am considering moving upto an I-optron cem120ec2 from my CGE PRO, does any one have any idea how the 2 physically compare in size (physical dimensions not weight !) ? The reason I ask is that at the moment my setup is in a skyshed pod on an Altair peir, with the CGE PRO sitting ontop of the electronics peir and then the 1100 edge hd and 80mm guidescope I am within 1cm of the top of the dome when closed in the park position. With the I-optron cem120ec2 not having the peir bit that is going to drop me lower down by about 10 inches ish , or would any one reccomend me getting the I-optron mini peir which I think is about 8 inches to put me in a similar position ? Thankyou in advance for taking the time to read this and replying Carl.
