When I use an 11mm Plossl eyepiece (almost 200x magnification) for example, I can easily see the Cassini Division in Saturn's rings. This prevents distortion of an otherwise sharp image. Water white glass is used in all Schmidt-Newtonian corrector lenses to maximize light transmission. If you can find the budget for this you will be stunned by the performanc vs price. I’ll give some reasons why and show some results that can be obtained with much smaller and less expensive equipment The Nexstar 8 SE upholds Celestron's reputation for quality optics. In general a Dobsonian telescope is a poor choice for astrophotography. Let's take a look at some of these 8" telescopes, mounts, and configurations. A masked composite of two photos shot at differing iso speeds to record Jupiter and its Galilean moons on February 16, 2015. The Corrector Lens fully corrects for spherical aberration and provides pinpoint star images. , Banner and Graphics by Luis Peres of Ziph Comics, Orion SkyQuest XT8 Classic Dobsonian Telescope, MEADE 0805-05-02 Lightbridge Truss Tube Dobsonian with 8, Celestron NexStar 8 SE Telescope w/ Fork Arm Mount and 40,000 + Object Database - Demo Model, The Observatory (find out whats interesting in tonights sky), Trips to Observatories and Astronomy Clubs, The Nerd answers your telescope questions, Nerd Guide to Getting the most out of a small telescope. Orion SkyQuest XT8 Classic Dobsonian Telescope - This is a tremendous upgrade from the 6" dob without being a tremendous price upgrade. This telescope is a way for you to get some great viewing and light gathering power at a very reasonable price. google_ad_slot = "8928077603"; You should make sure it has a 2" focuser. With it's technologically superior optical design, ACF gives a flatter, coma-free field of view with pinpoint images all the way to the edge of the field, rivaling Ritchey-Cretien performance at a fraction of the cost. Plus, a closed tube significantly helps keep the optics clean. The use of water white glass results in an increase of light transmission in excess of 10%, as compared to competitive telescopes using soda lime glass. The weight can be an issue. In this article I will walk you through a variety of 8 inch telescopes and go over some of the important points, and of course, I will give you some guidelines when it comes to price. Celestron NexStar 8 SE Telescope w/ Fork Arm Mount and 40,000 + Object Database - Demo Model Celestron's Nexstar 8 SE telescope combines excellent optics and computerized "GoTo" tracking in a package that's light, portable and affordable. google_ad_height = 600; Contact Us • Houston Astronomical Society, PO Box 6657, Katy, TX 77491Website related issues: [email protected] Dobsonian Mount 8" Telescopes Orion SkyQuest XT8 Classic Dobsonian Telescope - This is a tremendous upgrade from the 6" dob without being a tremendous price upgrade. Newtonion Optics - If purchasing a newtonian optical system telescope you have two basic choices when it comes to mounts. The 2" focuser is a very nice addition and will make a big difference in viewing and in comfort. You can purchase an equatorial mount which will give you accurate tracking, better observing and the option of automatic object finding and objec tracking. Bylaws of the Houston Astronomical Society. Schmidt-Newtonian optics are mounted in precision-machined aluminum cells, which are then mounted in sturdy steel tubes which are baked with high-grade textured enamel paint. As many sky observers know, the more light a tube can gather, the deeper into the sky you can see and the brighter and clearer the images. You can get some great bargains and these telescopes will typically be less than one half to one quarter the price of an 8" Cassegrain. The Cassegrain telescope will be more expensive (It has a more complex and better performing optical system) but this kind of telescope is very well suited to phenomenal viewing and this optic set up is often paired with the mount and accessories that make it a really high performer - extracting every bit of light gathering capability possible. In no particular order you can go with either Celestron, Meade, or Orion. You get 70% more surface area with an 8" than you do with a 6" and you get a significant increase in performance all the way around.

When I look at Jupiter, the pale orange color of Jupiter's famous Great Red Spot is visible, and I've even been able to identify the polar caps and spot dust storms on the planet Mars.
