Everythinghas been checked by me, and is fit for purpose.SPECIFICATIONS:Thistelescope will show all the basics of astronomy and it will make anideal telescope for starters or for those with some experience whowant a good telescope without the burden of weight and size! Opticaldiameter is 70mm and 900mm focal length = Ratio: f12.86Theimage in this telescope is nice and clear and the simple red-dotfinder-scope lets you point the telescope at the object you want tosee in the sky. The Finder-scope is perfect for locating the Moon,planets and bright stars.
ThisExcellent Offer Includes:ThreeEyepieces.Thistelescope takes standard 1.25 barrel eyepieces.Celestron20mm = 45xCelestron10mm = 90xH6mm = 150x(210xis the most this scope can use sensibly, but on the Alt-Az mountingfollowing the object can be tricky above 150X for beginners.)
PrismDiagonalThistelescope comes with a 90 degree prismdiagonal,which makes viewing highly elevated objects much more comfortable.Prism diagonals are less likely to give you trouble than mirrordiagonals which can tarnish not be perfectly flat. The prism, beingone piece of glass, is much more stable and reliable. It also makesthe image the correct way up for terrestrial viewing.
Finder:Afully working Red-Dot finder is fitted. It has a working batteryalready fitted and I will include a new battery as well.
Focuser:Anice rack and pinion focuser with a lock-nut on the draw-tube. Ihave also added a black 3D printed ‘shroud’ to the ‘back end’ (Seearrowed pic). This tidies up the horror that Celestron think is OK toleave hanging out of the back of their telescopes Leaving off theshroud is one of their cost-cutting efforts. (Google it, but have asick bag ready!)
MOUNTING:Comeswith the easy to use and intuitive Celestron simple Alt-Azimuthmounting with tube steel extending tripod as shown, which is veryeasytoset up and use. The telescope attaches with the ‘dovetail’ bar(Orange metal see photos) simply and easily.
ThisAlt-Az mounted refracting telescope mounting is very well suited tothe beginner to astronomical observation. The simple up-down /left-right movement is easy to get the hang of. Twist the long knobto tighten or loosen the up down movement. The left/right movementdrag is controlled by a small knob on the top of the tripod.
Thistripod has bracing between its legs, and is easy to fold away afteruse. It is very stable in use when the legs are fully splayed.Sorry No accessory tray.Weightis<5Kg so, it's light enough to move in and out for observing, evenfor children. Itis an IDEAL FIRST TELESCOPE!
THISTELESCOPE IN USE:Imaginebeing at the eyepiece of this excellent instrument observing themagical treasures of the universe beneath a coal black winter’s nightsky, slewing effortlessly from object to sparkling object, in yourpersonal programme of astronomical observation and discovery.

Whenyou feel like trying out an Equatorial mounting, this telescope willfit any that have the ‘dovetail’ fitting!+++++++++++++++++++++++++++++++++++++++++++++++++++++++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 soldby reputable telescope suppliers!) that I won’t and don’t allowthrough my door! Auctions are filled with instruments with secondrate, poor quality optics, ridiculous magnifications and outrageousdetail claims.
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 / Opticraft / Optus /Science Tec / Seben / Simmons / Tasco / Vision King / Vivitar /Zennox
Thereare also, sadly, many telescopes with well known mechanical failings,which I will rectify before sending it out. Buy another scope if youlike, take a chance, it’s your choice, but will it perform as well asone 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 a free after sales advice service. I know plenty aboutyour telescope and I’m happy to help with any problems you have andany query. 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.

Anyastro-photos included are taken with the actual instrument, unlessnoted. In which case it will be because of bad weather. The photowill be from another scope from the same manufacturer, with same sizeand focal length. I will not mislead you about the scope’sabilities.
+++++++++++++++++++++++++++++++++++++++++++++++++++Paymentvia PayPal only, please.
