Well, not really super secret, just some things you can do to make your life a little easier when operating the mount. I know several people own them on the forum, and several others have ordered them, so this one's for you.
Don't even think about performing a polar scope to mount alignment routine unless you do this, you will fail miserably and be very disappointed in yourself... There is just no way to keep the polar scope aligned axially with the mount without tightening everything up. Refer to the polar scope alignment manual on iOptron's website...it's listed along with the accessory polar scope ad.
Just thought of a mental note: To get the polar scope reticle perfectly square, you must loosen the RA lock knob, rotate the mount in RA until the crosshairs are vertical and horizontally aligned, then lock the knob. NOW rotate the mount in RA using the SLEW buttons to get it back to your mount zero point. That procedure had me scratching my head for a few minutes.
The most important, and necessary thing you will have to do is epoxy the upper tripod legs to the tripod sockets. Don't even think about not doing it. I used 2 part, quick setting epoxy from Ace Hardware. You will need some applicators (popsicle sticks) and some mineral oil or acetone to clean excess epoxy off the mount (and your fingers). At the bottom of each socket, there is a 3mm hole..plug it up with a piece of masking tape or suffer the drips of epoxy leaking out like I did. You will have to remove the spreader to perform this mod, easy stuff..screwdriver and pliers.
You may want to do something to ensure you always have a quick way to get back to your mount zero point (like when you accidentally unplug the mount during a slew) I used labels, you can try painting the raised lines on the mount also.
Here's another must do...the mount boss has too much play in the tripod recess, I was going to fabricate an alloy plate with a taper to eliminate the play, but found a 10 cent way to do it. I used 3M electrical tape #330, just wrap a length around the bottom of the mount boss to remove almost all of the play. It will still be loose enought to rotate in RA, but won't drive you crazy when you have to loosen the RA lock to adjust azimuth. If you don't do this, it's one step forward, two steps back when trying to polar align or when aligning the polar scope to the mount axis.
Here's a mod which is not limited to the SmartEQ...any polar scope will benefit. Remove the sloppy fitting polar scope and wrap a turn of Teflon Pipe Tape around the very fine threads. Re-install and enjoy. No more 3-5 degrees of movement when adjusting focus or accidentally touching it with your big eyebrows (guilty as charged) when performing a polar align.
Here's some common sense stuff, like what to do with the handset instead of watching it swing in the breeze.
Oh, another mental flash...the polar scope illumination is a bit bright, even at the lowest setting. Go give your wife a kiss and ask to borrow her red nail polish. Remove the top cover (4 screws) and dab the led with the nail polish, give it as many coats as you like to get the illumination to your liking. Nail polish remover is your friend. Oh, and if your don't have a wife, but still have red nail polish, you don't need to worry about a kiss....
I hope this info is of help to SmartEQ and EQ Pro owners and future owners.
Clear skies all,
