Losmandy AZ8 Alt-Az Dual Head Mount
Scott Losmandy is known for precision mount design and fabrication. The AZ8 is no exception. Like all Losmandy mounts, the Losmandy AZ8 Alt Azimuth mount is machined from black anodized aluminum with stainless steel hardware throughout. Fine needle bearings paired with high quality 7075 aluminum worm gears provide smooth, concise and controlled movement. 360 degree rotation of both axes is controlled by two slow motion knobs. Clear and easy to read 3.5" laser engraved setting circles help keep set up and tracking simple.
The AZ8 also boasts an impressive weight capacity via it's two head design. When properly balanced each side is capable of carrying 35 lbs. for a total carrying capacity of 70 lbs. Its motor-less design paired with the dual heads makes it the optimal choice for outreach and educational opportunities. Set an h-alpha scope on one side and telescope with a white light filter on the other for a side by side comparison or a small refractor with camera on one head and a larger refractor or small Cassegrain on the other for observing while doing short exposure imaging, great for lunar or solar imaging!
Highly versatile and very portable, each head of the Losmandy AZ8 offers a dual saddle plate capable of securely holding a V or D style dovetail. The head and tripod weigh a light 13 lbs. each and are compact in size the tripod folding down to just 29 inches. The aluminum tripod includes a 6 inch riser to keep mounted equipment clear of the tripod legs. Integrated bubble level and tilting tripod feet help ensure a level and quick set up. The tripod is easily adjustable up to 46 inches.

- Finally a robust alt-az for long heavy refractors
I bought the prototype at the Tucson Astronomy and Science Expo November 2014. I went there with a mount of this type in mind. I've got a home made 127mm surplus shed f9 refractor and a Vixen NA140. Both being long which easily induces vibrations in my other mounts. With BOTH mounted on the Losomandy it was very steady. However; they have a problem staying aligned with each other. One big scope, my Pronto or my WO66 this is not a problem. If the scope vibrates, it means one of the legs has not been seated properly. Which are pretty darn robust too.
I have used it several times for public out reach; very nice to be able to confirm that the user is looking at the right object but checking in the Pronto while the other person is still on the eye piece.
The version I got does not have the graduations on the axis nor the Losmandy logo.
It's a bit heavy (both good and bad), it has this funky pedestal between the mount and legs with the attachment knob inside making it a bit difficult to reach. Maybe even impossible if you have large hands. Which knocks it down a star from perfect.
But these turn out to be minor niggles while in use; it has been my go to mount since. For short views in the backyard or for longer use at outreach parties.
If you have a long slow refractor (especially if it has a lot of mass on either end) this is the mount you want. Highly recommend.

- Questions & Answers
Product QuestionsQuestion by: MNIzinski on Mar 14, 2015 5:44:00 PMWhat is the maximum height of the tripod & mount, measured to the middle of the altitude axis, including one 6" riser?It seems from the pictures that the azimuth slow-mo knob can get into a very difficult-to-reach situation at certain mount/scope positions, almost actually hitting the saddle at times. Is this a visual illusion or something that was unavoidable given design limitations?Question by: Bob K. on Aug 14, 2016 11:21:00 AMThere is an optical illusion in the picture, in that the AZ adjustment knob is closer to the viewer than the saddle plate, so there is no danger of them running into each other. As long as you use the mount with the AZ knob toward the front apertures of the scope(s), you should not have an issue with reaching the knob with the scope(s) in any orientation.Answer by: Chris Hendren on Aug 18, 2016 2:16:00 PMAloha OPT,
Is there some sort of alignment procedure that needs to be done in order to use the mount's setting circles? Are the setting circles accurate enough to locate DSOs? And are there any good 'digital' setting circles (and encoders) that can be used with this mount (to make this a manual 'push to' mount)? Thanks for you time.Question by: John on Jun 25, 2016 3:08:00 PMWith regards to the built-in setting circles, a lot of the answer will relate to the field-of-view of your system. The setting-circles are marked in 1-degree increments. So it is believable that with careful use one could get within 15-30 arc minutes with their help. If the FOV of the optical system is larger than that, it would be possible to land the object within view.
The larger difficulty would be synchronizing the circles to the sky, given that the AZ8 is not going to be tracking in RA (being a non-motorized Alt-Az mount). The process would involve finding a identifiable reference (perhaps a bright star near the object of interest), looking up its current Alt/Az position with a planetarium application (probably on your phone), then synch'ing the circles to those values, and finally moving the mount to the current Alt/Az position of the object of interest. That all being said, I think star-hopping with a good finder will be easier.
With regards to digital setting-circles for the AZ8, the manufacturers we work with are not offering compatible encoder kits, at this time.Answer by: Eric Blackhurst (Admin) on Jun 27, 2016 5:30:00 PM
