TheBresser 90mm f10 900mm FLAstronomicalEquatorial Refractor Telescope.
Thisfantastic, ten year old, 90mm telescope will show morethan just the basics of astronomy.
Thistelescopes was manufactured by the excellent Bresser Optical Companyto German engineering specifications.
Ithas been branded ‘National Geographic’, but despite this, it is everybit an excellent telescope!
Anideal telescope for for those with some experience who want excellentresolution in an impressive instrument.
(NationalGeographic have put their name to some shockingly bad telescopes inthe past! – This though, is a very good telescope.)
Opticaldiameter is 90mm and 900mm focal length Ratio: f10
Not just abeautiful instrument to look at, but also to look through!
Theimage, in this telescope is remarkably crisp and clear.
Eyepieces: 3
Ittakes standard 1.25 barrel eyepieces.
20mm= 45x
12.5mm= 72x
4mm= 225x
Themaximum useful magnification for this great telescope is350x. But you’ll soon realise that most nights, 225x is more thanenough!
That’s the atmosphere, not the scope’s fault!
Diagonal:Excellentquality mirror diagonal
Focuser:Excellentquality smooth focusing mount. Makingit easy to achieve a good focus.
Finder-scope:BresserType1 Red Dot Finder.Comeswith a brand new battery fitted.
MOUNTING:Comeswith the sturdy BresserEquatorial EQ3+Type Mounting with a tall, aluminium extending tripod as shown.
Makesure the scope is nicely balanced for best results of slow motioncontrols.
360degree worm wheel on both axes RA & Declination.Flexyknobs give precise control of scope direction using slow motion tokeep the objects in the field of view.
Mountingpolar axis is easily set for your local latitude. There’sa very clear latitude scale on the side.
Justpoint the main axis at the pole star and following the astronomicalobjects will be easy.
ThisEquatorially mounted refracting telescope is very well suited to theserious beginner in astronomy.
It has 18% larger diameter than Sir Patrick Moore’srecommended ‘minimal useful size’ 3 (76mm) refractor!It collects 40% more light than a 76mm scope, and it separetes 18% closer stars.
Weightis about 9Kg in use, so not too heavy to move in and outfor observing, even for young teens. It is a clever and compact design, meaning that it is easier tostore between observing sessions whilst at the same time remainingevery bit as good as any other 90mm f10.
This is anexcellent time of year to start your serious astronomy story.
WhatWonders Will You See?THISTELESCOPE IN USE:Imagine observing the beauty of theuniverse beneath a crisp, coal black late winter sky, slewingeffortlessly from object to glittering object, as you conduct yourown personal astronomical observation and discovery programme withthis superb refractor!
SOLARSYSTEM:
Thisimpressive telescope will show you much more than just the basics ofgeneral astronomy:-
Detailon the planets:
Mercuryand Venus:will clearly show their phases.
Mars:will show its disc, polar cap and markings on closest approach.
Asteroids:Follow the famous five on their journey through the stars.
Jupiter:will show its bands / belts and, of course, its four Galileanmoons:Io, Europa, Ganymede & Callisto.
Saturn:will show its rings and Titan,its huge moon easily, + 4 more.
Uranusand Neptune:will be visible as tiny greeny-blue tiny discs.
(Youcan’t reliably see Plutoeven with a 150mm telescope by eye! )
Moon*:You will be able toexplore the craters, mountains, rilles and valleys of the Moon whenit’s in a phase, and the ray craters when it’s full.
*Moonpic is sadly not taken through this telescope (cloudy). But it isrepresentative of the detail level available in this brillianttelescope.
DEEPSKY:Youcan easily see:-
TheAndromeda Galaxy (M32), TheOrion Nebula (M42), The trapezium is easily shown as four stars inthis scope.TheGreat Globular Cluster in Hercules (M13),TheDumb-bell Nebula (M27),TheRing Nebula (M57), TheSeven Sisters (M45) is a wonderful sight on low power.
DOUBLESTARS:EpsilonLyra: The Double Double. Two close pairs of stars.AlbireoBeta Cygni: Beautiful blue and gold pair.AlphaHerculis: Beautiful red and greeny/white pair.Alcor& Mizar: Wide white double, but Mizar is a double too!
At themoment we are enjoying the wonders of the late winter Sky. This meansyou can get your teeth into observing and learning to use your newscope in the evening without staying up late!
GREATFOR THE KIDS, EH?
All-in-allthis is a really superb telescope.
I have given it a thoroughcleaning and testing and find it very good. This scope willshow lots of detail, without breaking the bank or being too difficultto use.
=====================================================AboutME:Myname is Barry Cooper. I’ma second-hand telescope dealer.
Ido not sell rubbish telescopes! My feedback depends on it… Ihave 50+ years experience observing with telescopes. Isell only instruments that will be useful to amateur astronomers.
I’mnot selling this instrument because it doesn’t work right, or becauseI don’t know how to use it, or indeed because I’m trying to hoodwinkyou into buying something that’s not as good as I say it is. I selltelescopes to make a bit of money, obviously, but also because I wantto see newcomers to the hobby start off on the right foot. I want youtobe very happy with your telescope.
Thereare a lot of so-called ‘starter’ scopes out there, even being sold byreputable telescope suppliers, that I won’t and don’t allow throughmy door! The second hand market is filled with instruments withsecond rate, poor quality optics, ridiculous magnifications andoutrageous detail claims. You won’t find those in my auctions!
Iwould never sell any of the following makes, their optics are awfuland sometimes even plastic! Please, never buy any of these:Bushnell/ Edu Science / Jessops / National Geographic (Own Make) / Opticraft/ Optus / Science Tec / Seben / Simmons / Tasco / Vision King /Vivitar / Zennox.
Thereare also scopes with well known mechanical failings, which I willrectify before sending it out. Buy another scope if you like, take achance, it’s your choice, but will it perform as well as one of mine?
Mymission is to give you a great scope at a good start price (My BuyIt Now price is always very fair, but people, bless them, like tobid, don’t they? And I’m afraid, more often than not, the auctionfinishes above the BIN… But, I can’t help that!).
Ialso offer an after sales advice service. I know plenty about yourtelescope and I’m happy to help with any problems you have and anyquery. I’m always available on eBay message, or via email from mySupercooper Telescope Help website (Message me for details).
So,please read my feedback, absorb the advice on the website, and relax,you’re in good hands.=================================================================
