So I was going to buy a 32" LCD TV, but ended up deciding against it, since I don't have room for it in my dorm room! So I decided I'd get more use out of a new telescope. I already have a 10" dob which works very well for almost anything I ever wanted.
I want a telescope to kind of round out my collection, so I'm looking at refractors that I can use for planetary and lunar targets, and also remain more portable than my dob. I would like to be able to take it with me in my car to my dorm, so I can observe during the week, not just on some weekends. I also want a GEM mount, since I'll be using it for planets at (hopefully) higher mags. My price range is about $700. Is this realistic?
So, being new to refractors, my question is this: What type and size of refractor would you recommend? Also what brand is a good brand in refractors? How about focal ratios? I've been looking around, and the Orion SkyView 120 EQ looks nice. Thoughts?
Thanks, Sean

If you can get just a bit more money you could get a ED100 from orion. Its the best priced high power refractor on the market. Good for what your looking for. The 700 would cover the scope but the mount, thats where you need a bit extra. As for the Orion SkyView 120 EQ its a fine scope as many people here have said. It will show false color on the moon and planets, but it is a very good deal.

Wow, that Celestron there looks like exactly what I'm looking for! I was looking at the Orion EON 72mm APO, and the Celestron 120 achro is much cheaper (when you factor in mount/accessories). How bad is the color in this achro? Is it like the "coma" everyone worries about on fast dobs? 'Cause I never notice the coma in my dob, its not as bad as some people make it sound

Sean, can you mount a refractor on the EQ mount for the Tasco? It seems like your 4.5" newt should weigh as much as a 4" refractor. If you can use the same mount, I'd recommend the 100ED. You'll enjoy it for a long time... until you get a nice paying EE job. Then you'll be in Takahashi-Televue territory

The color is only really apparent on the full moon at high magnification, to my eyes. For the amount under your budget, you can get a Baader semi-apo filter if it bothers you. Some will tell you that it's under mounted, but I find it very reasonable for visual only.

A 120mm refractor isnt very portable, IMO. The mount required will be a beast of sorts. I suggest staying in the 80mm to 102mm range for the ultimate in portability. A well-made 80mm or 102mm will show a LOT!
Dont overlook Stelleravue as an option. Their scopes are terrific and so is their service. I, and many others believe that their products are a step above the standard "clone" scopes from various mfgs. You get close to the same pricing as the "other guys" but you get a personal touch and tighter "specs" & better build quality.
Anyways, I'd look for something a little smaller than 120mm if you really mean "portable". 
My 2 cents....

I would try this but the mount for the Tasco has seen... well, better days Its kind of sloppy and one of the slo-mo's is broke. So a new tripod and mount is probably in order. Although I will check out the mount and see if it can be salvaged next weekend.
I really like the new Orion EON's, an apo at a great price.. Is the 72mm too small? Should I get the 80mm? I guess the 120 would probably be too big for what I am aiming for. I would like it to be "grab-n-go" capable, and be able to be stored under my bed in my dorm
When it comes to planetary and clusters, how much aperture is "enough". I know in the dob world, an 8" is considered the "starting point". Is there an analog in the refractor world? In other words, will a 72 or 80 mm give me good images of planets and other bright objects? After all, my 10" dob is great for nebulae, etc.. 
Thanks for all the help guys!

I think a lot of people would say a 4 inch refractor is the most versatile place to start. Smaller refractors are more portable but show less detail -- bigger refractors require bigger mounts.
I think the new Orion 102 looks pretty nice. Astro Tech makes nice scopes, Stellarview, etc.

There are two levels of "portable," IMO. One level is "one hand out the door." Another is "airline carry-on." A 100mm scope is one hand out the door on an altaz or light EQ. A 72mm is airline carry-on. Some scopes combine airline portability with 100mm aperture, but you'll have to pay for it.
If you go with the 72, it will be airline/backpack friendly. If you decide to try imaging, the 72 will be a good place to start because of it's lightness and short focal length.

Wow, there are so many options. I looked around a lot today, and really like the Stellarvue's. The Orion EON's are just calling my name though
ranger, I looked for the Orion 102 you speak of, but only found one.. and its about $1K, a little out of my price range

Sean - A GOOD QUALITY 80mm scope will show great images of brighter DSOs and planets. Although I will admit that on the rare ocassion I wish had a larger scope, its usually when viewing planets.
I actually think a 6" dob is a good starting point, but yeah, 8" is obviously a little better. For refractors, many will say 4" is the minimum. Maybe Im spoiled because of a killer dark sky spot about 5 minutes from my house, but 80mm is perfect for a "starter" refractor. Mine has been out 5 straight nights for hours on end since the upstate, NY weather has been amazingly cooperative. Ive been through tons of Messiers, some brighter NGC's and whatever I else I can point it at. No cool down, no screwing around with elaborate setups...just point and enjoy!
I even talked a friend(property owner of dark sky site) into getting his first scope....a Starblast 6" reflector from Orion. The refractor setup was a little too much for him right now, but either way, he is IN! 
Anyways... thats my two cents.

If 72mm is enough aperture for you, the EON 72mm is on sale this week for $375, down from $500! I just ordered one.

IF it is in your price range, a 102mm scope is the optimum in aperature/portability.

Do like me get it all. I bought a 120mm ed scope for $2000.00 and a new mount to put it on then bought a 72 HDTV and a Blueray dvd player plus a new surround sound system and also book a 5 day cruise. My point is don't let the lack of money hold you back life is way to short to worry about what size to get or the price you have to pay. In the end its a small price to pay when it comes to your happness. Your only here once don,t hold back. Boy am I happy and for the the mere cash lay out of $10.000 dollar I was able to buy this happness.. I don,t know what to do frist watch my new TV or go look through my new scope. Now wheres that bottle of Jack Daniels.
