Subject: Advice Needed - Celestron PowerSeeker 127mm Telescope
|
Hi,
I have browsed through this group on google but would like some definitive
responses.
I am looking for a good first telescope and do not have an enourmous budget
however I don't want to spend what little I have on something less than
satisfactory.
Could anyone please advise on whether the Celestron PowerSeeker 127mm
Newtonian Telescope is any good ?
The specs are
€ Easy to assemble 127mm German Equatorial reflector
€ Pre-assembled aluminium tripod and accessory tray
€ Slow motion controls for smooth tracking
€ 3 x Barlow lens triples the magnifying power of each eyepiece
€ Finder scope: 5 x 24
€ Includes two eyepiece 1.25"
€ Includes CD-ROM 'The Sky' Astronomy software
€ Newtonian Reflector
€ Aperture - 127mm
€ Focal length - 1000mm
€ 1 x 20mm FL x 50 magnification
€ 1 x 4mm FL x 250 magnification
€ Optical Tube length - 508mm
€ Telescope weight - 7.17kg
Thanks in advance

What's a "bintel"? If you're in the U.S. and want an inexpensive dob,
telescope.com (Orion) is the best bet.

Hi,
After all my reading and much thinking I have obtained an 8" Dobsonian
I hope it lasts me a while.
https://www.bintelshop.com.au/Product.aspx?ID=6739
An image is here https://secure.attl.com.au/bintelshop/Stock/6739X.jpg
Bintel BT-202 08" Premium Dobsonian
Big aperture performance in a telescope even kids can handle. You can't
afford NOT to have a telescope with prices like this.
This BINTEL telescope has an expertly figured and polished parabolic primary
mirror made from BK-7 glass. It's guaranteed to be diffraction-limited,
meeting the theoretical limits of resolution for its size. The mirror is
mounted in an aluminium cell that allows rapid equilibrium of the mirror to
the outdoor temperature. A cooling fan is included to achieve faster
cooldown.
The secondary mirror is held in a fully adjustable four-vane spider.
BINTEL Premium Dobsonians are equipped with a smooth 2" Crayford focuser
without backlash.
Friction Control makes the Dobsonian easier to balance and easier to use.
The spring system stops heavy eyepieces from overbalancing the tube.
Standard Aceesories include: 26mm (2"), 15mm and 9mm Plossl Eyepieces, Moon
filter, 8x50 Finderscope, Base carry handle and Snap-on dust cap.
Every Bintel Telescope has been given a full checkup prior to sale. The
Optical Tube Assembly is thoroughly checked and collimated to ensure your
new telescope is going to perform as you would expect.
Specifications:
Aperture: 203mm
Focal length (f/#): 1200mm (f/6)
Limiting magnitude: 14.0
Resolving power:0.58 arc sec.

Hi:
Not a bad little telescope, perhaps. But my choice for an inexpensive
beginer's intrument? The Orion StarBlast, either the equatorially
mounted version or the dob version. You can see 'em at
<http://www.telescope.com >
Given my schedule and my weather, the little dob-mount StarBlast is
often my most used telescope. It's set up on the little pedestal that
Pat Rochford and I built for it next to the back door along with a
small box of eyepieces.
Without the little thing, I probably wouldn't have got the nice looks
at Comet Swan that I got. You can read my review of it here:

I am now tossing up between a Bintel BT-152 06" Dobsonian and the Celestron
PowerSeeker 127mm
The Bintel Dobsonian specs are
Telescope Type: Newtonian Reflector on Dobsonian Mount
Mirror Diameter: 152mm (6")
Focal length (f/#): 1200mm f/8
Finderscope: Bright 6x30
Focuser: Smooth rack and pinion (1.25")
Accessories: Plossl eyepieces 25mm and 9mm (1.25") and Moon filter.
So I guess my question, which of these would be best for a beginner ? The
Celestron EQ mount 127mm or the Bintel Dobsonian 6"

Dobs are not only easy to use, you can lean the sky using them. I have 3
dobs myself, ranging from a Stargaser Steve 4.25in F9 to a Donated 10 inch

The dobsonian would be easier for a beginner to navigate the stars with,
and the f8 would give high resolution views, but be somewhat lower in light
gathering capabilities than, say, an f5. But then, with the f8, you don't
generally have to worry about coma like you do with an f5 scope. Both
scope are f8, or nearly so, so coma shouldn't be a problem. Another factor
to consider is the accessories these scopes come with (or not). In some
cases, you might end up with a good scope that has few accessories, or
cheap ones. To me, this is one of the major considerations in buying your
first scope, because having lousy accessories could actually turn you off
to using your scope, or else, you end up paying more money for upgrades.

There are those who believe that life here, began out there, far across the
universe, with tribes of humans, who may have been the forefathers of the
Egyptians, or the Toltechs, or the Mayans. Some believe that they may yet be
brothers of man, who even now fight to survive, somewhere beyond the
heavens.
