Description

Losmandy G-11 German Equatorial Mount with 21 lb. Counterweight, Gemini 2 GOTO System, and Folding HD Tripod

The G-11 is one of the world’s best selling and most sought-after equatorial mounts. Based on the Russell W. Porter Slip-Ring design, this German Equatorial mount is manufactured with all-machined aluminum and stainless steel, and finished in black with a durable hard anodize. Removable stainless steel 1–1/4 inch diameter weight shaft w/safety knob. A 21 lb. counterweight is standard equipment, and optional 7 lb and 11 lb counterweights are available. The G-11 is rated for 100 lbs. total capacity (instruments and counterweights combined).

Polar alignment adjustments are precision and smooth. For initial polar alignment setup, the G-11 has two bubble levels and the mount’s latitude scale is laser etched in 2 degree increments.The equatorial head is supported by the Losmandy HD Folding Tripod with it’s massive 3-inch diameter, continuously adjustable legs for precise leveling. The mount’s 1.25-inch stainless steel polar axis is hollowed to allow through the polar axis sighting of the Northern or Southern Celestial pole, and an optional Polar Scope, to help make precision polar alignments quick and easy. The unique fully locking tangent arm design for altitude adjustment for aligning to the celestial pole is from 6–68 degrees latitude, and sports a large easy-to-adjust aluminum knob. The single knob azimuth control is bi-directional with +/- 8.5 degrees adjustment.

The Gemini 2 GOTO System with its 40,000+ object library has a full color graphic touch screen to clearly display all functions. The hand controller also has a tactile four button array on the reverse side of the touch screen console for times when you need to feel buttons to control the mount (such as when wearing gloves). Although the Gemini 2 is a stand-alone unit, it can connect to a host computer, and is designed for astro imaging and remote operation of the mount.

Scott Losmandy is the designer of the world-famous G-11 mount and tripod that works with most popular-sized telescopes for the serious astronomer. A lifelong amateur astronomer, designer, and machinist, Losmandy understands the functional requirements of demanding astrophotography and astronomy. His designs are characterized by precision all-machined parts in aluminum and stainless steel that are not only beautiful, but built with strength that will handle heavy payloads for a lifetime of constant use.

Exceptional Mount

A couple of years ago, I wanted to replace my old VMA200 mount with something more modern.
While visiting the Paris Astronomy show (RCE 2012) I noticed the Nova120. At that time, it was a brand new offering that I have not seen before, hence my hesitation to purchase
I wanted to purchase a E.U product to guarantee the quality and ease of access to support in my own language. I checked the forums and heard nothing but good things about the Nova120 so I decided to purchase it.

I have used enough astronomical instruments in the last 30 years to know what great quality is. The Nova120 coupled with the PRISM v10 and a CDK20 (508 mm) helped me pull off 900s unguided images with great ease. (Raw FITS File here). Payload of this setup is about 80 kg (160 lb).

The dizzying slew speeds, excellent accuracy and painless tracking makes this hobby easy and enjoyable again.
After using this setup for a year and a half, the only problem I had was rebalacing the gear after changing scopes. The superb electronics and software included make this tasks even more easier that just eyeballing the scope for movement due to unbalance.

You can very easily watch the motor consumption and know where the unbalance is....that easy. I have so much data that it is becoming difficult yo keep up.
I have absolutely zero regrets, this purchase has made everything easier: No summer/winter worm-gear adjustments, no guiding... just start imaging night after night after night.

Imaging Made Easy

Prism is my GoTo program for observatory control and imaging. Prism's many features make imaging taking a breeze.

I was concerned about giving Prism a try , especially as its quite expensive. So far Im very impressed and glad of my decision.
Im a beginner at all this so haven't tried other more recommended software, Prism appealed as it seems to do everything instead of using several programs 👍🏻

Great lightweight guide scope

This guide scope replaces a 400/80 that was waaay too heavy for what it did. The smaller 60mm scope does a great job guiding and I can RA balance with just one counter weight now - much better - and it looks like something Ferrari designed

Still learning Prism using Wireless links...

I have much of your software working at this time... I have it parked on my main computer, and a notebook... My main computer is a OverClock computer with 32 Gigs of RAM Clocking presently at 4400MHz with software parked on SSD drives... The rotation dome by NexDome is still not working... Most problems like this have to do with ASCOM Drivers... There is not very much detail information on how to use this software... I have to feel my way to a total operational staus... Second issue... The rain in the San Francisco Bay Area this year has limited my access to my larger telescope (12 inch SCT)... This rain has been so significant, I was force to weatherize my observatory... My goal here is,,, I am trying to remotely control my observatory totally. I have used Netgear Powerline 2000 to handle camera images and discover controlling rules to do that... High speed is vital for images with cameras over 3 Megs... I have both 12 Mega sensors and 24 Mega sensors... I am also using Netgear Nighthawk router and its mating extender to increase control signals to my observatory that is about 100 feet on the side of hill... I am also using Virtual Here software on a Raspberry Pi inside the observatory to solve the USB interface requirements... I started out using Model B and B+ on level 3 raspberry Pi's... I have moved to Level 4 Raspberry Pi to gain access to USB 3.0 technology... Big difference! I hope by early spring to have everything working... Bob Ritter MicTechS
