They can be unlocked, but if aligned, you will loose alignment and unless on a wedge, tracking will not be accurate. There are no manual slow motions, only electronic motions.

No. As I understand it, as soon as you release the clutches to manually push the scope to a target, the tracking is disabled. Once you stop and re-engage the clutches, you would have to go through a re-alignment to start tracking again.

You can use the hand controller arrows and slew the scope wherever you want with tracking maintained. But as soon as you release the clutches and move the scope by hand, you have to realign again.

My first thoughts and answer for you.....
You can manually slew to your first alignment target, lock the clutches, press align, at which point the CPC will ask you to enter your next alignment target which will have to be slewed to using the control and motors. Adding a second star, and even better a third, will make the traking spot on...if you do it correctly and choose good alignment stars.

Technically, the true answer to your question is Yes, it can. The CPC has a 1 star alignment but I don't think it's particularly accurate and is stated as such in the manual.

Short answer to your question, Yes, but I don't think you'd be happy with the alignment.

A generally accepted practice is when you start a session for the evening, you can disengage the clutches, push the scope quickly over to your first alignment star and re-engage the clutches. Then do a 2-star alignment using the hand control and electronic slewing from then on. As soon as you disengage the clutches, you'll have to re-align again.

Just found (on page 24) of the manual, the "Set Mount" command. Once you have good alignment, you can slew to a bright star, center it carefully, execute the "set mount" command, then loosen the clutches and move the scope to your heart's content. Then return back and center the same bright star, tighten the clutches and alignment remains. This technique is intended more for allowing you to free the scope to re-balance your counterweights in mid-session.

Getting close. Getting close! Pathetic: I've read the manuals etc, but no scope quite yet.

thanks for all the info, on this scope. i might pull the trigger too. i have celestrons nexstar 6"se and really like the setup procedure. would the cpc scope be the same setup as the nexstars and how do you deal with the cordwrap. i wont a larger scope in order to go deeper so im looking at the 11". the weight between the 9.25 and 11" in only 7 lbs, so i think i can carry 65 lbs out to my viewing area in my backyard (about 30 feet) im hoping i can just set it on a low pier without it falling over, not sure how flat the bottom is. thanks, don

You won't regret it. My 9.25 is not light but it is manageable. If you haven't seen a CPC in person, it'll prob be bigger than you thought, especially the 1100. The hardest part IMO is lining up the pin on the tripod with the hole in the base in a controlled gentle fashion, but you said you have a pier and I'm not sure how those are setup. The bottom is plenty large and it's flat with the exception of the 3 raised "keyed" areas that correspond with the negative castings in the top of the tripod. Shouldn't be a prob setting it on your pier.

I believe the default setting for the cordwrap feature is ON. I leave it on...better safe than sorry. I keep a close eye on my cables anyway but it's nice to know it's there's a failsafe.

Although the fork mount is well balanced regardless of where the scope is pointing at, and can be placed on any solid flat surface I'd be very cautious about just placing it on a pier without securing with bolts from underneath. An accidental bump to the fork arm can topple the scope off the pier. The flat surface at the bottom of the fork mount is small relative to the overall diameter of the console.

I think he means set/rest it on the pier while he secures it with fasteners of some sort... I hope!

I overcame cord wrap by getting the small Starizona battery that just rides easily on top of the mount base behind the on-off switch. A handy device and holds a charge well.

thats what i was wondering about, how flat the bottom of the console was. i have a lx10 8" fork mount that i just place on a table and observe, its flat all the way across. i will check on that battery mike. thanks, don
