Stargazing My New Telescope

  1. Dec 26, 2009 #1
    A while back, I posted here asking for telescope recommendations. After many members advised getting a dob, http://www.skywatcherusa.com/8-dobsonian-telescope-s11700.html" [Broken] is what I went with.

    I love this scope. Seems very well put together and can capture some pretty amazing sights. One thing that I wanted to confirm before doing anything about it are the ep's. It comes with two plossls (10mm & 25mm). They aren't the greatest and have seen others talking about how they replaced it with things like a 30mm tak and 19mm panoptic. Those ep's are both very pricey (around $200). I just wondered how big the difference would be based on what you guys know. Thanks in advance guys.

    Nice, basic scope with respectable aperture! You can get pretty good performance out of lower priced EPs, like TeleVue Plossls. I own several of them, and they are wonderful bang-for-the-buck EPs.

    If you are going to buy EPs, you should also buy a decent Barlow, and carefully plan your EP focal lengths to avoid duplication. For instance, if you bought a 40mm EP, you shouldn't buy a 20mm if you get a 2x Barlow, since you'd be duplicating the resultant magnification. You'd be better off getting a 40mm and a 30mm, so that in combination with the Barlow you'd have the equivalent of a 20mm, and a 15mm as well, with the advantage of having the nice eye-relief of the longer EPs. Short EPs usually have shorter eye-relief and can be more fatiguing to use for long sessions.

    By the way, the only "exotic" EP I have is an early Nagler. The plossls perform well with my 6" refractor. My scope is a 6" Apochromatic refractor from Astro-Physics, so I'm pretty picky about optics, and the Plossls are fine.

    Good luck.
