![]() Yes, you can move them with buttons on the hand controller without the star alignment, but this will become an expensive feature without the GoTo capabilities. You need access to the whole sky for this, which you don’t have through the window. You can’t use GoTo computerized mounts because you won’t be able to align them with the stars. I recommend only the alt azimuth mount because they are simple to use and more suitable for this purpose. You can only use telescopes on manual mounts for stargazing through the window. The other limitation is the actual telescope type you can use. Telescope type limitations through the window You are limited to only two objects: the moon and the planets. Moreover, if you live in the city, you can’t see any deep sky objects through the telescope because of the light pollution. Sadly the winter skies are the best for stargazing, and as you know from above, it won’t be possible to use the telescope from your room in winter. Not only that, but the night skies are rotating and are different in the summer and winter. You also have a limited night sky view through the window glass. Using the telescope through the window is quite challenging, and it gets worse. What are the limitations of stargazing through the window with a telescope indoors? Or at the locations where the warm temperature is the same all year round. The only time you can get around might be in summer when you have an equilibrium between the inside and outside temperatures at night. Unless you cool down your room to the same temperature as outside, which I am pretty sure you don’t want to do. In the wintertime, it is not possible forget about it. It’s called “thermal equilibrium” or “thermal optimization.” This is a massive problem if you want to use the telescope through an open window. The heat from the room will be escaping through the window, causing shimmer when you look through the telescope.Ĭan A Telescope Be Used through A Window? It occurs because of the difference between indoor and outdoor temperatures. The problem is the heat haze or heat shimmer. You might have an even worse experience than looking through the glass of a closed window. Using a telescope for indoor observation through the open window is not as simple as you think. Can you use a telescope through the open window? The only exception when you can use a telescope through the glass of the window is using it during the day to observe the outside world or spy on someone.īut even in this situation, you will get much better image quality if you open the window. The window will also block some light from the deep sky objects, which can contain reflections from your room or the outside world. The glass elements in the telescopes are manufactured to the highest quality, which is not the case for simple windows glass. The result is a blurry or distorted telescope image in the eyepiece. The glass on the windows is not perfect, and it distorts the light coming from the stars and deep sky objects. Even if you have a brand new and scratch-free window with the cleanest glass in the world, you should not use the telescope to look through it.
