Product Details

  • The Twilight 1 Alt-Az Mount with Heavy Duty Tripod by Explore Scientific:

    Sometimes you want your telescope, and you want it now! If you are lucky enough to own a big equatorial mount and a large aperture optical tube assembly, that isn't easy to do unless you have it all ready to go in an observatory. However, if you have a nice, medium-sized refractor and an uncomplicated alt-azimuth mount at the ready, then it is easy to get outside and begin observing in just a few minutes. That can be a real benefit on lots of occasions, whether the moon beckons or a comet is hanging near the horizon, threatening to set into the west while you are still getting your 12-inch OTA out of its case! Enter the Explore Scientific Twilight Mount!

    Explore Scientific Twilight 1 Alt-Az Mount with Heavy Duty Tripod:

    The Twilight I is a light-to-medium-duty alt-azimuth mount and tripod designed to quickly and easily accept small to medium sized refractors, such as the Explore Scientific AR102 or Carbon Fiber 102 mm, and of course, the 80 mm. Lightweight, fast Newtonian telescopes will also match up nicely with the Explore Twilight I mount. As long as your telescope does not exceed 15 pounds, you are good to go.

    The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45-degree angle, or you can point it straight up for viewing at the zenith. Slow motion control cables are attached on the vertical and horizontal axes and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. A small wrench is included with this package, and is stored in the fork arm and held in place with a magnet. If you need to make quick adjustments to your mount, it is a snap to access the wrench and then store it safely away when done. It is a small thing, but an adjustment wrench is one less tool you will need to remember to bring with you on observing sessions!

    The chrome-plated steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide footprint of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further and keep vibrations to a minimum.

Great Mount After Some Tightening

So like others said the instructions **** so I was expecting that. It came almost fully assembled so it wasn't super hard to figure out what pieces go where. What really bothered me is there was way too much play with the mount. Everything felt loose and sloppy. I had to take it apart to find where/how to tighten up the joints horizontally and vertically. I then had to go to around with my Allen Wrench and tighten up every screw on this mount. They were all not fully tightened. After that the legs needed tightening and they need two wrenches to do so. So getting this ready for prime time wasn't easy but once that was done it worked really well. I put on my 12.4lb Orion 150mm Mak. It had an additional 1.5-2lbs from the Diagonal, Baader Hyperion Eyepiece (kinda heavy) and a cheap light Baader red dot finder scope. I'm really close to the 15lb limit but it sure doesn't feel like it. I love Alt Az style mounts because I just walk outside my house any clear night to see Jupiter and Saturn right in my front yard. I move around a lot between trees to see them so this mount just makes sense. What I really love is the micro adjusters. They really make it easy to keep planets in view after I find them. They don't seem to be trying too hard either even though I'm close to the weight limit. I had my heart set on a ***** Porta II mount that could handle 20lbs because I might upgrade but couldn't find it in stock anywhere. This is for sure the next best thing. It just needs some tightening it to make it work properly and it feels like it can handle more than 15lbs.

Good Mount/Tripod

The item was well packaged, and in great condition upon arrival. There were small pieces missing that had to be replaced by a trip to the hardware store. The mount and tripod were difficult to assemble because portions of the instructions were a bit hard to understand. Through trial and error, it was finally assembled. This mount/tripod is rugged, portable, and easy to use. Because of it’s weight capacity, it is a great grab n go mount. The controls on it are buttery smooth, and very easy to use. Overall, it is a great piece of equipment.

ES Twilight 1 Mount

Sturdy, adaptable mount that I'm using as a grab and go with a ES 102 refractor and a C6.

Good solid mount

I bought this for a refractor that came with a cheap equatorial mount. The Twilight I is way more solid and precise and alt-az is much easier to setup and use for visual observing. If you’re not into astrophotography this mount is great and works for terrestrial viewing to boot.
