Excellent Scope
Purchased to use as for planetary imaging. All I can say is wow. Excellent optics, well made and the case is a nice bonus. Could not notice any image shift on focusing and the focuser moves smoothly and precisely. The provided eyepiece is also surprisingly good and provides beautiful clear viewing. The astronomical views through this scope are truly beautiful. I tested for terrestrial too and the views were stunning. Able to see the colour of a birds eye from over half a mile away. This scope is an absolute bargain at the £300 with next day delivery. This is the same 5" scope as supplied with the Celestron SE, nexstar, star sense etc, and has the Celestron XLT bright coated optics. Excellent quality telescope as well as terrestrial and delivery was spot in. Cannot recommend highly enough 👌

Biggest of the little scopes!
This is my C5 on the Celestron heavy duty Alt-az mount. Pretty good pairing. Old school manual analog setup. No electronics. My scope arrived with perfect collimation. The XLT coating makes the front glass look so clear, at a certain angle, I did a double-take to check if the glass was missing. First thing I did was replace the 45 deg diagonal with a 90 deg star diagonal. The finderscope is pretty much useless so that would change next. The travel case is much, much cheaper quality than I hoped, but it is free and useful so I can’t complain too much. I was strongly considering the C90 at first, but after reading many Cloudy Nights posts, I went with the C5. Overall I’m very happy with this gorgeous instrument, which was once worthy of being on the Space Shuttle. Can’t wait for the snow outside to clear up so I can put it through it’s paces. Clear skies, y’all!

Space, the final frontier, be prepared to spend the night out side seeing almost anything you want.Never doubt your ability.
The Celestron C5 is an advanced Schmidt Cassegrain device. The optics are well above expected in a 5 inch telescope. The design is both well thought out, and somewhat of a remarkable small package. I had to return one, the focus would not hold, however the one I have now is in a word " SUPERB " With the enclosed eyepiece the device will resolve at 50 power, minimal yes but big is not always better, first, the moon , what an incredible view, I was 5 years old when my grandfather showed me this marvel, well I have had a telescope of various makes for the last 50 years. yes a 12 inch device would without doubt be more than superior, but this marvelous 5 inch scope also will resolve Jupiter and the 4 major moons with incredible clarity, if you want to view it and are new to this amazing Jupiter will be at the 10 oclock position off the moon, it will be a very bright non twinkling light, the depth of such a small device as this is just remarkable. GET ONE it's affordable, you will not have a go to with this optical tube assembly, but any well supporting photo tripod will work very well, believe me you will appreciate this more as you actually learn how to plot a point in space and actually see something amazing resolve, because you made it happen, but definately get a go to mount later, but first test your navigational skills, I bet you'll be pleasently surprised. This scope is initially set up for 50 optical power, however it has a usable reach to 300 optical power, ...Now That is incredible. to sum it up light, star bright coatings, dovetail mount , mine currently is attached to a Manfrotto 755B with the 501 fluid ball head, a very stable platform,when properly aligned the only head movement closely resemble the right assencion with little to no declination adjustment, this is one gadget you will be able to enjoy by yourself or mentor an aspiring bright kid, they are waiting for someone to show them the hidden miracles in this life that a lot of people take for granted every day. any child between 8 and 12 y/o deserves an opprrtunity to first hand be blo0wn away by every day wonders hidden in the mundane daily grind called life.

Excellent télescope terrestre
J'utilise ce télescope pour l'observation de la faune terrestre par beau temps (le télescope n'est pas étanche), en complément de mes jumelles x10. Il est livré sans pied, avec trois accessoires en plus de sa valise légère de transport: la lunette de visée x6 (à installer et à régler), un miroir redresseur pour la vision terrestre et un oculaire de 25mm à champ large (je l'ai comparé à un Plossl 20mm, son champ de vision est bien meilleur, avec un excellent dégagement oculaire) offrant un grossissement x50. Tous les oculaires et accessoires astronomiques de 1.25p s'adaptent. J'ai longtemps hésité avec le C90, ce sont les commentaires d'utilisateurs des 2 appareils qui m'ont décidé: je ne regrette pas mon choix, le résultat est spectaculaire, notamment vis à vis du zoom de mon reflex (450mm). L'image est très définie, la luminosité au-delà de ce que j'espérais... Pour pouvoir prendre des photos, j'ai acheté un support téléphone à fixer sur l'oculaire et un adaptateur en T Celestron 93640. J'étais inquiet de l'ouverture limitée, mais je me suis tout de suite rendu compte que la principale difficulté était de régler finement la mise au point sans un trépied stable, et en trouver un n'a pas été simple: les pieds photo rotulés ne sont pas faits pour un objet de cette taille et cette masse (surtout lorsqu'un reflex est fixé au bout...). J'ai fini par acheter un Celestron Alt-AZ. Il faut s'habituer à la très longue focale fixe (1250mm) pour la visée. Avec un objectif zoom, il est très facile de cadrer en jouant sur la bague de zoom, mais ce n'est pas possible avec un télescope à focale fixe : le grossissement est tel qu'on se demande souvent ce qu'on est en train de regarder. Il est donc important de parfaitement régler la lunette de visée par rapport à la distance d'observation (la convergence dépend de la distance). Je pense acheter un oculaire zoom pour régler ce problème. J'ai testé ce télescope pour l'observation du ciel. L'oculaire fourni étant très lumineux, il est très facile d'observer Saturne et Jupiter avec leurs lunes. On voit très distinctement les anneaux de Saturne bien que la planète reste très petite avec l'oculaire de 25mm fourni. L'observation de la lune est réellement spectaculaire. J'ai acheté un oculaire Celestron X-Cel-Lx de 5mm et un autre de 2.3mm pour améliorer l'observation des planètes: les 2 étaient flous, il a fallu régler très finement la collimation pour voir apparaitre une image de qualité mais très sombre sur le 5mm, et bien trop sombre, floue et granuleuse sur le 2.3mm. Il ne faut donc pas aller au delà du grossissement théorique de x300 (oculaire de 4.16mm). Je pense que ce télescope n'est pas assez lumineux pour l'observation du ciel profond: toutes mes tentatives d'observation de nébuleuse se sont soldés par des échecs. Si vous visez essentiellement l'observation du ciel, un télescope de Newton avec une grande ouverture et des oculaires à champ large d'excellentes qualités sont probablement un meilleur choix (et permettra un meilleur réglage de la collimation, indispensable pour les forts grossissements, puisqu'il sera possible d'ajuster les 2 miroirs au lieu d'un seul pour un télescope SC). A noter que le prix du télescope a oscillé entre 480€ et 730€ lors de ma période de réflexion... soyez donc patients. En résumé, pour mon utilisation, c'est un outil fantastique.
