The Telescope
I spent over 5 years pondering and researching what kind of
telescope I that I would like and most importantly best use. I had a
lot of things I wanted to do with a telescope besides viewing. I
wanted to do Astrophotography down the line.
That eliminated one
very good scope: a Dobsonian. I also wanted a good computerized
scope with GoTo capabilities. Most importantly, I wanted
portability. This eliminated any reflectors. Anyway, it boiled down
between a refractor and a Schmidt-Cassegrain. I decided that the SCT
was somewhat cheaper per aperture and thus went with a 10"/254mm
Meade LX-200.
This scope is portable yet very heavy. I am a big boy
and it takes all my controlled power to lug this baby around! If you
are considering a SCT, be aware of the weight between the 8" and the
10" of Meade's line.
I feel I should plug the dealer who helped me a great deal not
only in obtaining the scope but helping me get acquainted with the
assembly and computer controls.
They were the only dealer who could
ship in under 3 months (less than 2 weeks). Their 2 sales members I
talked to both had an LX200 of their own. One spent 15 minutes
explaining an undocumented feature with me before a sale was even
made. Check them out at http://www.optcorp.com/.
The Accessories
I've read and now fully agree that when setting up a budget for a
scope, you need to put aside a good percentage of money for
accessories. I'd suggest about 20% of your budget be set aside for
them. I spent nearly $700 side items for the scope.
They Include:
| A must have: An Astro
Physics Maxbright 2" diagonal. It has a 99% reflectivity
performance and can be cleaned easily without scratching.
There is much debate over how much the reflectivity rate
enhances seeing, but I was convinced instantly from a light
polluted area. It seemed to me I could see much more (1/2 mg?) |

| A 22mm Tele Vue
Panoptic that has a 68 degree Field Of View.
You can read a good review of it here. |

| A 14mm Tele Vue Radian

- A 17mm Tele Vue Plossl
- A 2.5x Barlow from Tele Vue.
- A Dew
Shield. I recommend making your own instead.

Oxygen III filters are line filters that
isolate just the two oxygen III lines of the spectrum and
block most of the remaining spectrum. The resulting filter
yields the maximum contrast gain possible on planetary nebula
and most emission nebula. The Oxygen III filter is a visual
filter only, and is best suited to larger (6" or more)
telescopes of shorter focal length (f/11 or faster). |
 |
| A 1-1/4" Lumicon
UHC nebula Filter. get this one before the O-III.
The Ultra High Contrast Filter is a narrow band pass filter
that lets thru the two oxygen III lines and the hydrogen beta
line while eliminating most of the remaining visual spectrum.
The resulting filter yields high contrast views of all types
of nebula. The UHC filter is not recommended for photography,
and is best suited for telescopes of longer focal ratios (f/6
or longer). |
 |
| The Lumicon Deep-Sky Filter is a wide band-pass
filter which has been optimized for astrophotography. The gain
in photographic contrast is approximately 3-fold, which means
you can use exposures of up to three times longer before
reaching sky-fog limit when using the filter. Since
transmission for the nebula emission lines is over 90%,
emission nebulae gain 3-fold in contrast. Galaxies gain only
modestly in contrast (1-1/2-fold). Since the Lumicon Deep-Sky
Filter transmits in blue, green, and red bands, relatively
good color balance is maintained. This filter yields great
color astrophotos! |
