Scope recommendation

Greetings all! I've been looking at buying a new scope for about a month and it will probably be another before I get the money to get it. I've considered a countless number of telescopes and I am in that position now where the information/myths are just too overwhelming. I imagine this will be quite a long post, but if anyone out there would be willing to take the time to help me out, I would really appreciate it.

I am a 3rd year college student in New Orleans, and while the skies are horribly light polluted, the city has its own advantages ;o) I am looking for a new telescope as a peaceful "get-away", as an alternative to reading, television, surfing the net, etc. My ideal observing session would be sitting behind the eyepiece of a scope, sketching planetary and brighter deep space detail, generally enjoying the view, while offering a peek to whoever is around, just to give you an idea of the type of observing I would like to do.

My budget is around $1000 complete including worthwhile acessories (although I have a bad feeling I'll find some way to justify spending a couple hundred more).

About 6 years ago, I bought a 4.5" Celestron newtonian. It served me well for a year or two until my parents didn't want it in the living room and it became a centerpiece in my room on which to put track medals, leighs, stickers, etc. This was probably a combination of mediocre images, running out of things to see from my backyard, unessesary bulk, and poor mount.

I'll have plenty of floor space/movable furniture in my room, so size isn't much of a problem, but portability certainly is. I need a scope that can be comfortably carried (with mount) down the hall and up a flight of stairs to a top-floor patio in one or two trips (much preferably one). I am willing to invest about $100 for a carrying case that can fit the entire scope or just the OTA. By the way, if anyone's interested, I've heard that golf bag cases meant to transport golf bags as luggage make great scope cases when padded with foam. An $80 case with wheels can transport a 6" refractor tube. Not a bad idea! Also, the scope needs to be easily shipped/put in storage a couple times a year. While I'm fired up now, realistically I don't see myself driving out to a dark sky site more than a couple times a year. It should also be able to handle long car drives for drives back home to NY.

I am particularly interested in detail; that is, enough detail to make a good sketch. While hunting for faint fuzzies is fun for a while, this can be done from any scope (even if the "faint fuzzy" is M57!), so its not my highest priority. I would like to see detail *within* Jupiter's cloud belts, as well as on Saturns disk and rings, give nebulas and galaxies at least some defined shape, etc. Basically, considerably more detail than my old 4.5" reflector, enough to make setting it up worth it.

I'm not sure what kind of climate conditions contribute to seeing. Let's just say that its almost always like a sauna during the summer, but nice temperatures in the winder/spring months but the high humidity still lingers. On the bright side, cooldown isn't a problem then its usually warmer outside at night during the summers anyway.

So, in a nutshell: the scope needs to be able to handle moderately high magnifications (about 200x), but also be able to give a good view of a wide star field with a good eyepiece (although with light pollution, I don't know how impressive this view will be, I would still like to have to ability if I ever find myself under a dark sky). Good contrast/resolution is a high priority. I also wouldn't mind paying a little extra for high-quality optics.

So that's about it, thanks for taking the time to read this. If anyone has had experience in my situation/conditions, your reccomendation would be most helpful. I would go to a star party, but there really aren't any clubs here or back home. While I have a few scopes that I am interested in, I would like as many "clean-slate" reccomendations as possible, so I won't mention them.

Clear skies and thank you again,
George

Well, George, I don't have any experience in N.O., but an online friend of mine who uses the screen name Qazaq is a resident of your town and a dedicated sidewalk astronomer. I'm sure you would find his insights valuable. I'm going to ask him to post here, but just in case, he can also be found hanging out at a couple of other boards where I use the name Skyjim - google that and you'll find us.

Clear Skies!

I just bought a Stellarvue 80/9D off Astromart as a gift for a nephew. Had never seen one before, but bought it on reputation and reviews. My regular scope is a TV-102, which I love.

Long story short: the 80/9D can do what you want and then some. VERY impressive for the money. Sharp, high-conrast views.

It's not color free, so you might want to check that out first. I'm picky, and it didn't bother me.

Views held up extremely well at 187x with a 4mm Radian. That's enough to show you the planets and moon, including the detail you are looking for, very nicely. Moon is wonderful. I'm sure the Orion nebula would be terrific, as would many open clusters. You would get a nice look at the brighter globulars, and resolve some stars in some of them.

Here's a $1300 budget:


$450 for the scope

$100 for a 2-inch diagonal

~$375 for telepod head and tripod

$375 for EPs.

Pretty close to what you targeted, and a lot of lasting value.

Hope this helps.

Steve

An LX90/Nexstar 8/etc. might do the trick. You can find them around for $1,000, a Williams Optics 2" diagonal for $100, a couple of ep's for another $100 and a decent 2" barlow for $100. More or less the goto SCT is a quick set-up and gaze. You can always add items as you go along. The f/ratio is decent. Otherwise go for the Atlas EQ10 by Orion. That is a lot of scope and a decent tripod for the money. It will also take a long time to get aperature fever. I've owned 8 scopes in 3 years of astronomy and I missed a 10" LX-50 the most. It wasn't the most portable. I do like my 140mm refractor paired with a GM8 because of portability. Personally I'm looking to add more aperature with a Celestron 9.25 sct if I have the money, otherwise the Orion Skyview 8" reflector ota for under $300. Point is, start with something you want, if you don't like it sell it and start over. Good luck, Don

My first telescope was a real cheap 4.5" reflector on a lousy mount with a hopeless finder, that I bought from K-Mart 20 years ago. The images were really sub average.

But 10 years ago I came across the accurate details about how to collimate it. It now still works marvellously for what it is. I remember seeing lots of fine detail on Jupiter as Comet Schoemaker-Levy left a big hole in it. Despite having several other telescopes including an APO, I still use it occasionally.

And I'm pretty sure that your Celestron should be much better than my old one. By all means get another telescope, but I'd also invest the 15 minutes or so required to collimate your old one, and get it working properly.

I'm surprised only one person has recommended an Nextstar 8. I have a C8 on an eq mount and it's a good all-round scope, and a complete system would fit nicely within your $1000 budget. I must admit I haven't looked through any of the Russian scopes that have been mentioned so can't say how they compare, but I have compared the C8 to an EXT 105 and the images are comparable, with the C8 being a bit brighter.

Even though cooldown time may not be a problem where you live, dewing might, but that can be minimized with a dew shield.

I can lift the C8 and eq mount with one hand, and I'm not Arnold Schwartzenegger.

Thank you everybody for your input, I certainly appreciate it.

I am gravitating heavily toward the MK-67, but am (again) considering a 8" SCT such as the C8 or LX10. What I want to know is, does the superior optics of the MK-67 make up for its loss of aperature (and higher cost) compared to the 8" schmidt? Remember, this is coming from a mainly planetary-detail perspective from a light-polluted sky.

And how would the 8" SCT compare to the Orion 5" Mak or Skyview Pro 120mm synta refractor on planets? (in case I can't afford the Intes)

Thanks again,
George
