Quote:Hello TahoeNoob and welcome to cloudynights. I highly recommend a 2x Barlow like the Orion shorty to get good planetary closeups. I also would get a 7.5 or 6.3 mm to power up in good seeing, useful for close double stars, lunar, and planets. The 25mm is a good low power eyepiece. Great for star hopping. Maybe a 17mm or 12.5 mm for midrange, all Plossls. I am thinking of a 2" for myself, perhaps in the 25-32mm range. Premium eyepieces really are nice and the views are great if you can get them like the panoptics or ES 32mm, but they are beyond my budget.

Quote:Depending on your budget, I would also recommend a low power wide field eyepiece. Moving up and out to a 2" low power, wide field eyepiece will enable you to take in some wonderful large patches of sky and really put objects in context with their surroundings. The 10" dob has good wide field capabilities that you should take advantage of.The TV 31mm Nagler coupled with a Paracorr is the gold standard for gorgeous wide field views in your scope, but... The 30mm ES° eyepiece strikes a good balance between price and quality. For around $250 you will get huge enjoyment ...
Quote:... also, from what I understand, you're centering a shadow that bounces back from the primary mirror, not the actual laser light that bounces back. As a result, they say it doesn't matter if the collimator "wobbles" a little bit in the focusing tube. I saw a YouTube video where Howie even demonstrates this. Starting at about 9:10:http://www.youtube.com/watch?v=sd3stObWI_IIf that's the case, does it really matter what type of collimator you use?

Quote:Even so, I think I'm going to go with an Orion Deluxe Collimator. I can't justify spending that kind of money on a collimator. Maybe later, when I find out that my system doesn't work, I'll see things differently.
Quote:TexasRed is right. For now, use the Cheshire/sighttube combo. More accurate collimation would only really be needed for AP.
