iOptron MAK 152mm, 1900mm Focal Length / f/12.5 Maksutov-Cassegrain OTA


iOptron MAK 152mm, 1900mm Focal Length / f/12.5 Maksutov-Cassegrain OTAThe iOptron Rumak-type 152mm Maksutov-Cassegrain is perfect for the serious amateur astronomer who wants apochromatic refractor-type performance at an affordable price. In fact, the multicoated optics provide almost similar results as a 5-inch apochromatic refractor -at a fraction of the cost. You will be amazed at the images you'll see with the MAK 152mm-surprisingly, an f12.5 that can view Jupiter's cloud bands and also M31. The precision design and engineering of the optics produces images you would not expect in such a light tube. The MAK 152mm from iOptron is the only MAK of its kind that comes with a dual speed focuser for fine-tuning your images. Also included is an attachable dew shield - rare for a MAK - for better performance in cold temperatures.
  • Rumak Style Maksutov-Cassegrain optics
  • Aperture: 152mm
  • Focal Length: 1900/ f12.5
  • Eyepiece holder with compression ring

Celestron 8 Inch CPC EQ Wedge Schmidt-Cassegrain Telescope

Celestron 8 Inch CPC EQ Wedge Schmidt-Cassegrain Telescope


Celestron 8 Inch CPC EQ Wedge Schmidt-Cassegrain TelescopeThe Celestron CPC telescope is an amazing instrument for visual and astrophotography use. The Celestron CPC telescope is an Alt-Azimuth mounting style telescope. Astrophotography is possible and done very well in Alt-Az mounted telescopes however most will tell you that an Equatorial mounted telescope is the right choice for serious astrophotography. That's why we have combined the Celestron CPC telescope with the Celestron HD Pro Heavy Duty Wedge. A "wedge" is a piece that mounts inbetween the Tripod and the Fork Mounted CPC telescope. It "changes" the telescope to an Equatorial mounted telescope. This allows you to polar align your telescope and will minimize the tracking that is done on a standard Fork Mounted Alt-Az CPC telescope. The Celestron CPC Series Telescopes are fully computerized GPS enabled GoTo telescopes. They feature Celestron's revolutionary SkyAlign technology (when used in Alt-Az mode without the wedge) and feature 40 000 objects at the push of a button. This Celestron telescope package is the best way to get started into Astrophotography with a Celestron CPC telescope.
