Telescope Buyers FAQ
http://home.inreach.com/starlord -- "In this universe the night was falling,the shadows were lengthening towards an east that would not know another dawn. But elsewhere the stars were still young and the light of morning lingered: and along the path he once had followed, man would one day go again." Arthur C. Clarke, The City & The Stars SIAR www.starlords.org Bishop's Car Fund http://www.bishopcarfund.Netfirms.com/ Freelance Writers Shop http://www.freelancewrittersshop.netfirms.com Telescope Buyers FAQ http://home.inreach.com/starlord "Livingston" wrote in message ... Hello, I have been observing for some odd two years now. I have bought my equipment small and cheap up until now. I have an Orion 70mm refractor, a pair of 12x50 Scenex binocs, and just got a pair of Celestron Skymaster 15x70 binocs. The Celestrons are being serviced right now, they came out of alignment and produced double images. Thing is, I am ready to move up. I want to be able to magnify what I have observed more, and would also like to go deeper. Seeing m13 as a faint fuzzball and only detecting the inner most portion of the Andromeda galaxy is a real drag. I am satisfied with the binocs, it is cool over time your hands learn to steady themselves. The telescope though... I tell you. I feel like a gymnast sometimes with the positions I must get into to aim that thing. I am 6' tall, so the activity of trying to target any object over my head where observing is best is just plain impossible. I got fed up trying to target the Andromeda galaxy the other night. I have no interest in auto finding systems. I want to learn the sky. Auto drive might be nice, but appears costly. It is easy enough to tap the scope with my fingers, and this has a certain earthy feel to it. I enjoy the work. I figure I should go for a dobsonian, and have honed in on the Orion Skyquests. I have a number of questions though. It really is a choice between the 6", the 8", and the 10". I could have the 6" right now, or I could wait and save for the larger sizes. What has been your experiences? Will I find great limitations with the 6" in terms of light gathering power? I am drawn to the 8" really. How is nebula observing with the 6"? Something I have never done yet, I mean I have yet to see much more of the Orion Nebula than just the wispy cloud like haze surrounding the sword star of Orion, and I do believe I have read the Orion Nebula actually covers an area 6 times the size of the Moon in the sky. I suppose I have read all Messier objects can be seen with 7x50 binocs, but c'mon, the Owl Nebula in those? Please. How would the Messier list be with a 6"? I assume it would work well. In addition, once again I see a finder scope design that looks like it will keep me exercising all through the evening to target objects over my head. What options are there to avoid this? I tell you what I would really like, a laser pointer for a targeter, but I assume that would be illegal because of the minute infinitesimal risk to pilots overhead. How do experienced observers solve this dilemma? Also, for those who have used a Skyquest, is it easy to move as objects slowly rotate? Does it stay on target until you decide to tap and move it? How about a fine focus? You see, on my 70mm refractor, the whole thing gets going vibrating when I focus, so I am forced to feel where the sweet spot is with broad sweeps and then try to hit this spot. Needless to say, I always get close, yet when observing Mars recently I pump the thing way beyond it's limit to 232x sometimes. If I could get that sweet spot, it would not be all that bad an observing experience, but it is hard to do. Also, I see Orion recommends a laser collimater for the 8" and up, but not for the 6". Any idea why? Does it go out of alignment less? Is doing this job with the included cap easy enough for those with some mechanical ability? Or, should you get the laser tool? So, feedback? Advice? - Livingston |

Thanks, FAQ read. But, it did not answer my questions.
I hope there are some folks around here who like to chat. I see from the thread speculating men did not actually land on the moon that this corner of usenet is quite similar to the rest of cyberspace... Pres. Reagan sure did goof when he largely defunded our mental health institutions. No disrespect to the paranoid amongst us, they keep people honest and they make life more colorful. One note on your FAQ: there is a tone of being concerned with, or at least aggravated by, what others think of your abilities, equipment, etc... who the **** cares? Unkind people who take the opportunity to look down at you over such unimportant material concerns are usually really just exposing their own inner sense of inferiority and need to lift their selves up stepping on another. Personally, I do not care if some neurotic wants to exercise his superiority complex. I want to enjoy the amazing beauty and revel in awe at the grandness of space and it's apparant perfection. I always figured people who enjoy this hobby are exceptional in their spiritual development, and that I would not encounter this namby pamby weak spirited a-Christian competitive bull**** at a star party gathering. I certainly hope I am correct, I have never met a coarse person who looks up and wonders at the magnificence of it all. They are too busy getting drunk and chasing pussy. [chuckle] Just joking, somewhat... So, any one else wish to help me out, or is this group a dead zone? The finder issue is the one that really burns for me, I want to be able to target over my head, which is practically impossible now. - Livingston On Sun, 27 Jul 2003 15:15:06 -0700, "Starlord" wrote: Telescope Buyers FAQ http://home.inreach.com/starlord |

You might also think about turning to the ATM field, while it took me 4 years to
gather together the needed parts from people on the Internets, I was able to put together a nice F8 8inch dob which I named Babylon 8 and because I had a lot of help with it, I ended up spending less than $100.00USD for all it's parts. My case is not the norm, but if you do the work yourself, you might save some money on your scope and you'll know it inside out too.

In article ,
says... Cool, I have noted over the past few years that the group of people I encounter on the internet appears to be thinning in the places I visit. It could be due to the fact that people sort of have their fill of the net and then go back to life! vbg. Astronomy like most other hobbies has it's gear heads. I've just read the warped me outside of my own culture. When I was young, I always figured people would grow up and out of the imbalanced competitive spirits... oh well. In my twisted view of life what I see is the web being used as one gigantic brag book ... the number of websites that are little more than 'look at me and my toys' is astounding. Hehe, the main reason I gave up on astronomy clubs about 30 years ago was the terminal BS slung by the members and the non stop "one up-manship" crud that goes on.

Oh no... since I am new, I simply have been assuming it would not be this way. Do I get to be popular if I purchase a 32" Ritchey-Chretien for my own custom installed backyard observatory? Good grief... Hell yes! If you own a 32" anything you'll be a big cheese. It's not a dead zone lol. Overhead targeting huh, have you considered a right angle finder with amici prism? I will look into it, I have never heard of this before. I hope it gives a wide field of view so I can get my bearings without using my line of sight. I suppose using a laser pointer is out of the question because of safety concerns? Bummer, it would work so well... University Optics make one sweet Amici prism'd 8x50 viewfinder. It's field of view is around 8 degrees which is ideal for general locating of objects and for serious star hopping. The page with the finders is as follows www.universityoptics.com/acc.htm Price is around 180 USD. Your other alternative is something like a Telrad, a device that projects a red dot on to the area of sky being viewed. It's a 'unit' finder and has no magnification. A lot of amateurs swear by them. I think I am going to readjust my finances a tad and just buy the 10" Skyquest dobsonian and resolve my other concerns. I really am interested at this point in magnifying objects (i.e. Mars) more and capturing the classics clearly. Why get stuck at 352x or 480x when I can just go to 600x if I sacrifice a few other things? Then I may not wish to invest in other equipment for a while too. I know plenty of amateurs who've never gone over 6" mirror size and have spent their life observing. Really high power observing such as 600x with a 10" really requires an equatorial mount or a dob on one of those equatoral type platforms, as the planets transit time across the eyepieces field of view is extremely short, with times of a few seconds being normal at 600x. I find my best views of the inferior planets at around 250-300x as most nights the seeing just isn't good enough. Peace to you too. Unfortunately, good seeing appears to be the largest challenge in this hobby. Clouds, clouds, clouds... I think I get perhaps 2 really good viewing days per month in Ocean County, New Jersey. And five mediocre ones. The weather patterns we have been in here are relentless and merciless. I am glad no one videotapes my many vulgar diatribes as I curse Mother Nature when I miss celestial events due to the weather. Be glad you don't live on the south western side of Austalia. The winter (right now for us antipodeans) is cloud and more cloud for 13 out of 14 days for a few months. In the past 3 weeks I've had all of 2 nights observing, 'nuff said! I have a friend who lives in New Mexico, and another who lives on an island off of the coast of British Columbia, Canada. Needless to say, I will be coming to a couch near them at some time. I cannot imagine looking up and seeing the Milky Way, I must have this experience. Must, I tell you, I must. I get it from my dark site, which is all of about 50 minutes drive from the city. Perth being a small joint of under 1.4 million people means I don't have to drive far to get to really dark skies. I was using the binocs the other night, and being somewhat clueless I looked up and thought I was looking at a section of Leo. No, it was Cephius, the bright triangle of stars was deceptive for me.

When I stayed up to count Leonids last year at my old home, I only saw 128 in two hours, and perhaps four fireballs. I know what you mean, I keep pretty detailed records of limiting visual magnitude at my suburban location here in the central north part of Perth and it's deteriated noticably in the past 5 years. It's nowhere near as bad as what you'd experience though. The Leonids here were a real fizzer, hardly any show last year and through broken clouds I saw all of 16 over a 3 hour period. Unlike 2000 where from 500km north of where I live I got a real treat. Like most meteor showers the Northern Hemisphere tends to get a better 'show'. Oh well it's time to do the work thing ...

The only input I have is that Orion makes a really nice 9X50 right-angle
finder that fits right on most Orion scopes. I put one on my newtonian dob and I love it. Under $80 (US) if I remember right. I could never use a straight-through finder with my back.

It seemed like a good idea to me, I bought the Orion 6 x 30 right
angle finder scope last evening. Figured a newbie like me should have as wide a field of view as possible. 7 degrees versus 5 for the model you mention. Thanks. - Livingston On Thu, 31 Jul 2003 20:38:31 -0500, "Scutter" wrote: The only input I have is that Orion makes a really nice 9X50 right-angle finder that fits right on most Orion scopes.

That would appear to take a lot of know-how I do not have.
To tell you the truth, after reading this: http://home.earthlink.net/~flyj/mccluneytext.html on collimation, I will probably just have it done for me professionally. I am somewhat mechanically inclined, but I would think the margin for error here is quite small. Thanks. I bought the Skyquest 8" Dobsonian and compromised. - Livingston On Mon, 28 Jul 2003 12:45:12 -0700, "Starlord" wrote: You might also think about turning to the ATM field, while it took me 4 years to gather together the needed parts from people on the Internets, I was able to put together a nice F8 8inch dob which I named Babylon 8 and because I had a lot of help with it, I ended up spending less than $100.00USD for all it's parts.

![]() Hell yes! If you own a 32" anything you'll be a big cheese. Oh, goody... [frown] Bah humbug. If I ever do have $100,000 to spend on my hobby, perhaps... I will befriend the kind, be they meek or equiped with expensive equipment. Here, drool: RC Optical Systems http://www.rcopticalsystems.com/ http://www.rcopticalsystems.com/32inch.html They have a nice gallery too. I believe I read somewheres the 32" goes for someodd $99,990. I ended up buying the 8" Skyquest Dobsonian. With a 5mm and a 40mm wide view eyepiece pair to complement what I already have. Along with a 6 x 30 right angle finder scope and a planesphere. All for a modest $670. I hope to be wowed after two years of observing with low power equipment. University Optics make one sweet Amici prism'd 8x50 viewfinder. It's field of view is around 8 degrees which is ideal for general locating of objects and for serious star hopping. The page with the finders is as follows www.universityoptics.com/acc.htm Price is around 180 USD. Your other alternative is something like a Telrad, a device that projects a red dot on to the area of sky being viewed. It's a 'unit' finder and has no magnification. A lot of amateurs swear by them. The Orion 6x30 I purchased was $49.95. Since my current finder has a big fat crosshairs in the view, I fail to see how a laser dot would help me much. I was wondering if the finder actually casts the dot on the sky itself, but I figured that would be impossible to do without working just like a regular laser pointer, i.e. illegal. The Orion page shows the view looking through the finder scope, and made no mention of it casting a pointer dot. Be glad you don't live on the south western side of Austalia. The winter (right now for us antipodeans) is cloud and more cloud for 13 out of 14 days for a few months. In the past 3 weeks I've had all of 2 nights observing, 'nuff said! Here, right now, as we enter August and Mars approaches, we have seven straight days of clouds and rain forecast. I am getting irritated... I get it from my dark site, which is all of about 50 minutes drive from the city. Perth being a small joint of under 1.4 million people means I don't have to drive far to get to really dark skies. I need to find a good dark site near me. Just moved here, I will do so soon. Thanks. - Livingston |
