The OTA is extended by untightening three thumbscrews, pulling up the secondary mirror assembly until there’s a subtle click into place, and then retightening the thumbscrews. This feature allows it to be stored more compactly than a traditional dobsonian. The main difference between this telescope and others of its size is the collapsible “FlexTube” functionality. The SkyWatcher FlexTube 200P is an 8” f/6 Newtonian (203mm Aperture, 1200mm Focal Length), with the same optics as those found in Orion, Apertura, Zhumell, SkyWatcher Classic, and GSO dobsonians. The SkyWatcher FlexTube 200P set up on the pad at GTCC’s Cline Observatory, before guests arrive.
#Explorer 200pds review upgrade#
As a first telescope or as an upgrade from a smaller telescope, I can highly recommend it. Its compact collapsible tube is very useful, and its ease of use is fantastic. The accessories are useful, and there’s plenty of avenues for upgrades owing to the 2” focuser. Overall this is a highly recommendable telescope.
#Explorer 200pds review manual#
(Beside, a GoTo manual isn’t very fun to read compared to a finder chart or an observing guide.) GoTo scopes in this price range will be even smaller, to the point where there’s not really anything you can see with GoTo scopes at this price that can’t easily be found manually. However, such telescopes are not good beginner instruments as their mounts are difficult to understand and set up. Telescopes like the Omni XLT 150 newtonian, the Omni XLT 102 refractor provide quality, serious instruments on high-quality German Equatorial Mounts. Other quality telescopes in this price range will have smaller apertures. GSO in Taiwan makes the telescopes that are sold in the US under the names Zhumell and Apertura.
What you’re differentiating is the value of different accessories and the price. Pretty much any 8” dobsonian you can buy is going to have pretty much identical optical performance. If you must keep the telescope up in the house and must take it downstairs to get it out to a place you can observe with it, or you’re physically disabled, or out of shape, or you’re buying for a child you may find yourself rarely using the telescope-in that case, a tabletop dobsonian such as the AWB OneSky/SkyWatcher Heritage 130P, Orion StarBlast 4.5 or 6, or Zhumell Z130 might be a better option due to their Grab-N-Go capability. The weight concern, which applies pretty much equally to all full-size dobs, means that it’s not necessarily a good fit for all observers.
