I have here an AstroTrac TT320X-AG equatorial mount with scope for sale. It’s designed to compensate against the movement of the Earth to allow very long exposures of the night sky without blur. It’s ideal for both wider-angle shots and deep sky images using a DSLR and long lens, or a camera mounted on a small telescope. It gives up to two hours of tracking, and if aligned accurately, is remarkably precise. The image I’ve included of the Andromeda Galaxy was shot with it, using a 400mm lens and a DSLR.
The tracker comes with the scope included (normally sold separately), as well as the power pack, which takes 8 AAs. The device is about the size of your forearm.
I’m selling because I just don’t get the time to use it any more. Condition is generally good, but there are a few signs of use. Note that the scope, which attaches magnetically, has a bit of a loose connection so sometimes flickers on and off at certain positions on the brightness knob. I enquired about a replacement screw-on LED part but at 40 I didn’t bother. It’s not really a problem – you just might have to turn the brightness dial slightly every now and then. If you’ve not used an equatorial mount before, it’s important to know that you’ll need two tripod heads, which of course don’t come with the tracker. The AstroTrac doesn’t come in its own box, but I have printed out an instruction manual (also available online) and it will be very well packaged for delivery.
Retail price new is around 508 for this kit (https://www.tringastro.co.uk/astrotrac-tt320x-ag-3019-p.asp). Any questions, please ask. Below is some more info…
The innovative TT320X-AG is an ultra precise and compact equatorial tracking mount. The perfect solution for capturing great images with your digital SLR camera. Experience super accurate unguided tracking in a quick to setup and easy to use package. Spend more time doing astrophotography and less time setting up.
MORE BANG FOR YOUR BUCK!With the TT320X-AG you can take longer exposures at longer focal lengths allowing you to create brighter, less noisy images.
The TT320X-AG is fully compatible with the AstroTrac Polar Scope, Pier, Counterweight Bar System and Wedge. We strongly recommend purchasing the Polar Scope to allow you to achieve a good polar alignment and you will see this as an option in the drop down menu next to the price.NEW! – AUTOGUIDINGGet pin sharps stars at longer focal lengths with the TT320X-AG’s right ascension autoguiding capability. Compatible with popular ST-4 autoguiders such as the SBIG SG-4, Orion Starshoot, LVI SmartGuider, and with popular autoguiding software such as MaximDL and PhD. Autoguiding requires an additional cable which you need to order seperately.SUPER ACCURATE UNGUIDED TRACKINGThe phenomenal unguided tracking accuracy of the TT320X-AG has to be seen to be believed. You can easily capture pin sharp stars at 200 mm or more focal length. The only other mounts which can match the unguided tracking accuracy of the TT320X-AG cost many thousands more.Most DSLR camera exposures are around 5 minutes or less. The TT320X-AG has typical unguided tracking error of around 5 arcseconds peak-to-peak or better over a 5 minute period.Your TT320X-AG unit is individually calibrated at the factory, so the tracking rate is exactly right. You don’t need to waste time measuring and adjusting the tracking rate to make sure its running at just the right speed to prevent your images trailing.ULTRA PORTABLEThe TT320X-AG is remarkably compact – its roughly as long and as wide as your forearm. Put it in your suitcase or your computer bag and take it with you whenever you travel.The ultra portable TT320X-AG weighs only 1 kg (2.2 lb). Despite its minimal weight, the TT320X-AG can easily carry 15 kg (33 lb) of cameras, lenses and telescopes. And you don’t need to worry about lumping large power supplies with you either. The TT320X-AG draws minimal power, so you get around 10 hours tracking from a set of 8 AA cells. AA cells also have the advantage of being available just about anywhere in the world.QUICK TO SETUP, EASY TO USEYou can setup the TT320X-AG and start imaging in minutes. Step out into your garden and take advantage of short gaps in the cloud.SpecificationsWeight1 kg (2.2 lb)Load capacity15 kg (33 lb)Tracking time2 hrsTracking ratessidereal, solar, lunarAutoguidingin right ascension with ST-4 compatible autoguiderTripod mounting threadstandard photo 3/8″ 16 tpiWedge mounting screws3 x 4 mm x 12 mmTH3010 scope mountingstandard photo 3/8″ 16 tpi or 3 x 4 mm x 12 mm screws
