I am thinking about buying a Newtonian Reflector telescope, it is a short tube with a focal length of 1400 mm with a moon filter and a sun filter. Does anyone have this telescope or know anything about this? I would like to know if this is a reliable scope or not.

6 inch lens/mirror
Lens clear aperture : 150mm

6 inch is a good size for beginning. I assume that it also comes with about a 6x finder scope attached. You will need one. You will want two eye pieces 25 mm and maybe 10 mm. You will use the 25 mm most of the time. That will give you 56x. The 10 mm will give you 140x, but the image will not be as bright. Mostly you will use the 10mm for viewing the planets, moon, and double stars.
Now there is one thing you need to be aware of--maybe more than one. A Newtonian requires periodic realigning of the mirrors. Be prepared to know how to do that. The next thing you need to know is that to get the most benefit from the telescope you will need to observe under dark skies--except for the planets which are very bright. You will also need to buy a star atlas. Sky and Telescope sells a super one. They are on the internet. You will need the atlas to help you find the dim objects such as galaxies, nebula, and star clusters. They can be a bear to find if you do not have stars to use as a reference.

As you can see, astronomers are a little sensitive about being mislabeled as astrologers, and with good reason. But for the most part the quality of your question will earn your forgiveness.
The telescope that you describes is a good starter scope. It is widely used in college level astronomy labs and can see a fair number of deep sky objects as well as most of the objects within our solar system.
My only word of caution is that you be very careful and know darn well what you are doing before you aim the telescope at the sun.

I favor the Meade telescopes myself. And just a gentle reminder - you want to talk about astronomy. If you say astrology to someone they with be confused.

astronomy = the study of stars and such
astrology = fortelling the future by looking at the stars or some such.
you're looking at a decent scope. meade is the top name brand, go for that if you can.

It's astronomy. Not being rude. This is a common mistake.
