Hi,
I'm about to purchase a first telescope and have considered the Meade LX90. I've capped my budget at £2K. I have never done astronomy before and just want to be able to set up in the garden, find some interesting objects to view with minimum fuss and maybe take some photos with a compact digit camera if possible (35mm available if no alternative). My questions a 1. Is the LX90 a good choice and what other choices in this price range are worth considering? What kind of viewing experience is achievable regarding planets, galaxies etc with this power of telescope? 2. Is the LX90's GPS option (£169) worth it, what's the impact of not having it? 3. Is there any other major component that I need to add to my starter pack in addition to telescope and tripod? 4. Has anyone successfully mounted a compact digital camera (mines a Cannon S50) onto a telescope and produced worthwhile results? Many thanks for your advise and comments |

If you haven't done so already, I suggest hooking up with your local astronomy club and getting a look at and through a variety of scopes. What kind of viewing experience is achievable regarding planets, galaxies etc with this power of telescope? You should get good sharp views of the planets, nice views of the various sorts of DSOs, open clusters and globulars will be nice, various nebulas and galaxies will be exciting, depending on how dark your local skies are. 2. Is the LX90's GPS option (£169) worth it, what's the impact of not having it? From what I understand it just helps orient the scope and maybe provide an accurate time. It is not needed IMHO when compared to other more useful accessories. 3. Is there any other major component that I need to add to my starter pack in addition to telescope and tripod? a. Either a dew heater or dew shield, maybe both. The corrector plate is relatively thin and exposed. Dew forms with form on it very readily, fogging it up and causing various difficulties. This should be standard on SCTs IMHO. b. Eyepieces. In the US, Meade buyers can purchase a nice set of Plossl eyepieces for an additional $99. It is a definite bargin and provides a decent set of eyepieces to allow viewing most any target at an optimal magnification. 4. Has anyone successfully mounted a compact digital camera (mines a Cannon S50) onto a telescope and produced worthwhile results? I am sure it has been done. Planets and the moon are pretty straight forward. Deep Sky Objects get trickier because of the longer exposures required. The S50 is capable of 15 second exposures, probably get some images of brighter clusters, I really don't know. For long exposures a Wedge is required so that the scope can be mounted equatorially, not sure how that is done with the LX-90. jon |

I second Jon's comments. I bought an LX90 as my first scope, and am very
glad I did. The downsides to it: 1. The tripod is 20 lbs, the scope and mount are 33 lbs. So depending on your strength, it my not be terribly portable. 2. Like all SCTs, it does not have a wide field of view. So you'll likely find planets, the moon, globulars, and DSOs your favorite objects; open clusters won't be terribly impressive, because you won't see all of them. 3. Will take 30-45 minutes to cool down and get excellent images (though most 8" scopes will take the similar length of time for this). Now for the upsides: 1. Most people have found their LX90 to be very reliable. 2. GoTo helps you learn where everything is. The LX90 is pretty accurate, when aligned properly and calibrated. 3. Lots of support from other amateurs, books, magazines, and the web. There's a yahoo group on the LX90; superb source of info, both for newcomers and experienced people. 4. If Meade still has their eyepiece special on... a great deal. Take it. 5. The Meade LPI option ($150 here in the US) is a great way to start on astrophotography. You will need a dew shield and likely a dew heater. Comes with living in England. Buy an issue of Astronomy Now, and find one (or more!) astronomy clubs nearby in the clubs listing section. Attend a star party so you can freeload views from various kinds of scopes. We're all quite happy to share and deliver our opinions. |

Many thanks to everyone for their comments and advise. I will certainly try
and hook up with some locals and benefit from their experience. Regards, Phil "David Feindel" wrote in message ... I second Jon's comments. I bought an LX90 as my first scope, and am very glad I did.
