Happy with it
I managed to see a little Jupiter, it was an incredible experience, and of course you can see the moon, but I recommend to buy a lent for 4mm

That's bad, stay away.
This is for decorating your home; if you want to see planets, stay away from this model and invest more money in another one. This one is purely for decoration.

Als b-product/retourproduct gekocht bij Amazon. Maar deze had niet verkocht mogen worden. Kwam niet netjes aan. Open doos, rondslingerend product. Verder niet over geklaagd, maar toch, bij deze. Product zelf is ook waardeloos, behalve als leuk voor op de kast. Had een cadeau moeten zijn, maar helaas. Er zit een spiegel in die je niet kan stellen, wat wel zou moeten, zou je het een beetje willen gebruiken. Deze spiegel zit gelijmd. Dus het is echt alleen om naar te kijken maar niet om mee te kijken.

Rozczarowuje co mozna zobaczyc. Sprzedawane jako teleskop do wielu obiektow na niebie. Niestety zobaczycie tylko ksiezyc i to tak srednio dokladnie :( by zobaczyc ksiezyc nieco fajniej (np. Kratery) to trzeba dokupic osobno soczewke 4-6mm. Gdzie sensowna bedzie kosztowac od 50% ceny calego tego teleskopiku do 150%… niezla rzecz na prezent, ale tak naprawde powtorze, tylko do obejrzenia ksiezyca :(

Leve, fácil de transportar. Sei que vou ter que investir em objetivas e uma barlow para um maior aumento. As que vêm com ele têm qualidade razoável, mas são de 10 e 20 mm somente. Mas como é um produto durável e cujas imagens podem ser melhoradas, pelo preço e praticidade, gostei.

IMPORTANT! You will not see Jupiter as large as in the pictures of the "vanilla" FirstScope. This Cometron version comes with different eyepieces than the Celestron FirstScope with the names of astronomers on it (the "vanilla" FirstScope). The Cometron verrsion comes with 20mm and 10mm eyepieces, yielding 15x and 30x magnification, respectively. The "vanilla" version comes with 20mm and 4mm eyepieces, yielding 15x and 75x magnification. You can still see Jupiter and its moons with the Cometron version, but they look like stars. Despite the lack of extreme magnification (which frankly will look blurry with such a small scope), this scope is a wonderful device! I've used it every clear night since it arrived (about three weeks ago), and I am never disappointed. The included finder scope is a bit of a pain to zero in properly, as it is manual and not an electronic red dot scope, but it works well after some effort. The moon is wonderful, as is seeing star clusters which are invisible to the naked eye. I have not gone out to a dark sky location yet, but I am sure this scope will only impress me even more.

Pues si, estoy contento con el, las lentes son de calidad, lo he probado y cumple con lo esperado. Esta claro que no es lo mismo que otros telescopios con mas apertura y longitud. Pero buscaba uno que pudiera colocar en la ventana, ya que vivo en un piso, y para observar la luna y algún que otro evento me vale. Le he comprado también una Lente Barlow. Como digo no esperes ver los cráteres de la luna como si estuvieras dentro, es un telescopio pequeño y yo valoro la relaciona calidad precio. Tengo otros dos, mas grandes, pero ocupan mas espacio y es inviable montarlos en casa, por lo que son los que llevo de excursión. Hay que ser conscientes de que si quieres mayores aumentos vas tener que subir el nivel de gasto en el telescopio, y por supuesto en unas buenos objetivos.
