Questions & Answers

DONNA CHERNISKY C : Can I hook up my Nikon D7000 to this somehow to get pictures?WILLIAM N : Yes. You need to buy the Celestron 1.25 inch universal T-adapter (Adorama part number CNTA1Q), and a Nikon T-mount (MDNTM). You might need to remove the right angle prism and put the t-adapter directly into the end of the telescope. However, this arrangement will be a bit awkward. The telescope is not really meant for astrophotography. You can take some moon photos, which are short exposure, but that's about it. It can be used like a terestial telephoto lens, but you might need to add some counter weight to offset the weight of the camera.HENRY U : Since my 4" telescope is too bulky to tote, I purchased ET-80 which is great to tote around in my truck and can attach my Cannon T4 with a special attachment accessory. Great telescope but I will never purchase anything from Adorama. They sent me a broken telescope base without the backpack and although they replaced it with a new telescope, they refused to reimburse me for the 30+ dollars postage for returning the telescope. This was the second time that they refused to pay postage for returning a defective merchandise. This is just my personal experience and have been purchasing from other reputable dealers although some the items were cheaper at Adorama.DAN D : The technical answer is "yes". If you get a Nikon-specific T-ring as well as a T-adapter you could likely achieve focus. There are also frames you can get in order to do afocal imaging/digiscoping. But you really should not be getting this telescope for imaging purpose. It is an achromat so you will have false color and the mount is a very bad choice for astrophotography. For astrophotography you want a VERY good mount. The quality of the telescope and the camera is not as much a priority as is the quality and robustness of the mount. So you may be happy with this scope for visual use, for astrophotography it will be nothing but frustration.
Shopper : does this scope handle motorized controls?LAURIE C : not that i know of
Shopper : Why Did You Choose This?THOMAS S : From researching online it seemed like the best pick for a beginner for myself so i hope i enjoy it.

Rated 5 out of 5

Perfect Choice to beginners

I was in my first Astronomy class. And there were about 6 more telescopes. I thought others would be better then mine. They looked amazing and bigger. But when we used them, my telescope was the most interesting for the people. Images sharply and easy to use. I recommended it to a 15 people i think.

If you're looking for a dual-purpose telescope appropriate for both terrestrial and celestial viewing, then the AstroMaster Series is for you. Each AstroMaster model is capable of giving correct views of land and sky. The AstroMaster Series produce bright, clear images of the Moon and planets. It is easy to see the moons of Jupiter and the rings of Saturn with every one of these fine instruments. For views of the brighter deep space objects like galaxies and nebulae, we recommend the larger aperture and light gathering ability of the Newtonian reflectors.

  • Permanently mounted StarPointer
  • Erect image optics - Ideal for terrestrial and astronomical use
