Hi there, have recently acquired an Altair Astro Sabre 2 Alt-Az mount:
and am contemplating attaching an inclinometer as a means of getting in the ball-park of an object in terms of altitude. Most decent inclinometers on the market use a magnet for attachment, unfortunately there is a distinct lack of ferrous metal in my kit, the only element apart from screws with magnetic capability is the Vixen counter-weight. Interested to find out how other people might have tackled this situation. Encoders and DSCs not an option at this moment in time, although will look to go down this route sometime in the future however at this point would probably look to swap out the Sabre for something like an AYO Digi II.

Kind Regards
Paul J.

I used a Craftsman Torpedo Level on my Dob for exactly what you're trying to do. With a layer of red tail light repair tape, the backlit display was just the right color and brightness.

You could put a piece of magnetic adhesive strip on your ota and put the inclinometer there. The field strength from the strip won't be strong so you may find it a better idea to put the inclinometer there only during use. Amazon has a variety of these strips.

Hmmm... I had contemplated this approach, however I have an aversion for corrupting such a pretty looking OTA with 'yucky' adhesive . On the otherhand, since the dovetail clamp is a 'drop in' it just occurred to me that I could use this solution on the dovetail bar. Or... perhaps on the rear cell, provided there is sufficient magnetic traction with the tape, to hold the device in place.

If you use a Wixey style inclinometer, a small piece of white foam tape will hold it securely and you can remove it when you want with no damage to the OTA. I've done this many times.

If you wanted something more low tech you could do something with a protractor, string and weight on the other side of your mount with the counterweights

I use 3M Command Strips anytime I'm sticking something to my scope/mount. Always comes off without leaving any film. Last telrad I got I removed all the foam tape just so I could replace it with the Command Strips.

Great feedback guys, definitely got some options to pursue now. Don't let me stop you though, keep them coming

Think I'll veer away from the protractor, string and weight though, I think the last time I used a conventional pre-digital age protractor was in college, think this has long since gone the way of the slide rule...

Here's another question to consider. What sort of accuracy have you guys managed with this sort of arrangement? I'm hoping that I'll be more or less in the correct latitude for an object, which should allow a simple pan in azimuth to bring the object into view.

Hey...the string and protractor will never run out of batteries
