    Default Orion AstroView 90mm Equatorial Refractor Telescope



    Greetings fellow members! I just joined the forum and I'm fortunate enough to be surrounded by the wealth of knowledge and information provided here. I recently got bitten (again) by the astronomy bug and I'm seriously considering fully committing to the hobby. I've researched endless hours reading through articles and reviews regarding purchasing a decent beginner and even some intermediate-level telescopes. The Orion AstroView 90mm Equatorial Telescope seems to have all the features I would want (Moon and planet viewing, deep sky observation) and at around $300, it's at the upper range of the budget I'm willing to spend. It's received generally positive reviews; however, after searching the forums for some feedback regarding this particular scope, there doesn't seem to be that many. I just wanted to see if there are any members out there that have this scope and what their thoughts were. Thanks!

    Welcome to these forums...

    I personally do not consider the Astroview 90 ( f/10 900 mm scope) as a general purpose scope...

    I own and use an Astroview 100 ..(F/6 600 mm scope) it too is not a general purpose scope..

    The AV 90 is a good lunar and planetary scope..and at f/10 it still will have some false color which I'm betting you will still need to buy a minus violet filter to tone down... However it is not going to go "deep" (no deep sky observations as you put it)

    My AV 100 is just the opposite .. at f/6 and 600 mm it is designed as a low power, wide field scope.. And that is why I purchased it..to use only on open clusters and star fields.. that I purchased sticky to use on open clusters and star fields... my AV100 has a hard time reaching 100x and has a ton of false color (yellow ring around the moon)

    The AV90 should be able to get up to 130-140x on a normal night and will have much less false color and will have a much smaller FOV..all of which is perfectly fine for a planetary or lunar scope..

    I'm completely satisfied with my AV100 but it has a limited usage and it sure is not the only scope I own.. IF you are a Lunatic (lunar observer) the AV90 will do the job...My AV100 is terrible on the moon not so great on planets but kicks tailends on star fields and open clusters.. The AV 90 will do a good job on planets andf the moon but just will not cut it for deep sky..

    I think you will be much better off spending the same money on a 6 inch Orion Dob or blowing the budget by 50 bucks and buying a 8 inch Orion Dob (or any other Dob Zhumell AD etc..) just as good if not better then the AV90 on the planets as well as the moon BUT very very much better on deep space...

    Hi Bob! Thanks for the informative reply. I should have stated in my initial post that my primary needs for a scope are for lunar and planet viewing with and if possible, deep sky observation. I do realize that Dob reflectors are more well suited for this purpose; however, a big reservation for me towards purchasing one is portability (or lack thereof). I would like to easily transport the scope and I would favor the more compact and lighter refractor counterpart vs. let say, for example, a 6 or 8in Orion Dob.

    I know the refractor vs reflector scope is a highly beaten topic, but from what I've read, it seems refractors require less maintenance, yield more contrast and sharper focus, and have the portability factor, which is the reason why I'm opting for a refractor. Again, this is strictly from a general comparison standpoint and I'm aware that each possess their complementary advantages and disadvantages. In the end, my experience with the scope I ultimately decide to purchase and understanding its limitations will determine the utility I get out of it, but I also want to make an informative purchase. Perhaps is there a refractor scope (within $300) that bridges the gap between the deep-sky capabilities of a Dob reflector? Thanks again for your input. My research continues...

    Your AstroView 90 is not bad for a "Starter Scope", at least nowhere near the "disappointment-level" of the average WalMart / BestBuy "stuff" that fits your stated $300 budget.

    Realize that it is not the equivalent of scopes which others purchase for several times the price of this scope. They are usually scopes of larger aperture or better glass, and you usually DO get more when you spend more.

    But, that being said...

    I do own an AstroView 90, which I have usually used remounted on one of my CG5 Mounts. I've even taken it to a couple of Public Star Parties, setup side-by-side with a wide-field Orion ST80mm scope to give folks a quick example of the differences of a longer vs shorter "budget" scope. Folks liked both configurations, but favored the AstroView 90 for viewing Planets and the Moon.
    At F/10 and 90mm, you can easily view a number of Gobular Clusters, Open Clusters, Binary Stars, and even some of the brighter Galaxies and Nebulas, as well as the local Solar System.
    If $300 is the budget you've set for your intro into Astronomy, its going to be a bit difficult to find a better package for a refractor mount finderscope and eyepiece.

    I am interested in buy the AstroView 90 and I wonder if you can tell me the ID of the lens cap? I am guessing it is around 105mm.

    Greetings everyone! I just joined AF today and was excited to find this thread because I ordered the Orion Astroview 90 earlier this week and am anxiously awaiting its scheduled Friday delivery. Along with the scope I also ordered a GSO 2x Barlow lens. As this is my first telescope, although I have looked through larger ones belonging to friends and at a couple of star parties a few years ago, I'm really excited to get it assembled and out for a first light. I welcome any suggestions for any accessories, tweaks, etc that you might have for maximizing my beginning viewings.

    I own an AV 90 and happen to think its a darn good scope. My only complaint is the mount, after an hour of messing with it I got out my Vixen Polaris that came with my Celestron C4.5. I wish I could use the wooden tripod but it sits to low. if you get one I don't think you will have buyers remorse.

    For those in the market for a similar scope you might give the Orion Skyview Deluxe a look. I managed to get one (which I paid an insanely low price for) and the mount is very solid and stable for what it is. No, it won't hold a candle to my Sirius mount, but it cost over $1000 less! So far I have been very happy with this as a visual scope. It is light, easy to set up, and no maintenance required. The only thing is I don't really like the finder and have not found an adapter yet to switch it over to a newer style finder mount.

    My new AV 90 arrived today!! Was pretty easy to set up, but man did they ever have a lot of grease on the GEM gears! Took it outside and zeroed in the finderscope and then laid in a pretty good, at least I hope it is, polar alignment using two compasses and then marked the tripod leg locations for later tonight. Now I'm just waiting for darkness to finally set in (LOL, the scope would have to come on the Solstice!!) so I can give it a first try. I'm sure that as a total beginner I'm won't be able to give any real insight on how things look through it, but I know I'm really excited to try it out.

    Well Fabiga, what do you think of your new scope? What are your thoughts on the EQ mount? If the tripod is a little shakey what I did was shorten the tripod until the top of the legs are even with the tray and it helped a lot, I might be a little shorter than you but go as far as you can.
