You can further look for the telescope with the parabolic primary mirror to avoid problems with spherical aberration. 130mm aperture and 650mm focal length will give us f/5 scope which is a great light collector. So, let’s say we can use a telescope with common specifications. It will allow us to collect more light during the 30s exposure than with a slow telescope. The shorter focal ratio also means that the telescope will be fast. The short focal ratio will allow you to photograph wider objects like M31 Andromeda galaxy or beloved M42 Orion nebula. With high focal ratio, you will end up with too much magnification and smaller field of view. And the shorter focal ratio is the way to go. The focal length of the telescope is also important. This aperture will collect enough light to get good results with a 30s exposure. However, if we want to stay in the budget, we will be happy with 130mm aperture. So, how big aperture is suitable for astrophotography? The answer is the bigger, the better. Because of this, you can do shorter exposures what is essential for us because we are going to use altazimuth mount with limited exposure time. Newtonian reflectors have bigger aperture than refractors so they can collect more light.
Next reason to use reflector is that essentially, it is a light bucket. Therefore because they are cheap, we are going to use a reflector. Dedicated reflector for astrophotography has a specific design and shorter focal length to reach focus with DSLR. On the other hand, the reflectors are also used for astrophotography, and they are quite cheap, but they have to be specially made for it. So, it’s obvious this is not the way we want to go. These telescopes cost thousands of dollars.

The most common telescopes used for professional astrophotography are very expensive Apochromatic refractors. Telescope(OTA) For Budget Astrophotography Moreover, altazimuth mounts are very easy to set up compared to EQ mounts. I also go out with the telescope, but I spent most of the time on the balcony. AZ mounts can be aligned without the Polaris. I don’t see the Polaris from here because the view is obstructed, so AZ GoTo mount was the only option for me. It is a major factor because you can’t properly align EQ mount without the Polaris. The advantage of the altazimuth mount is that you don’t need to see the Polaris for the star alignment. It is also my case because I’m doing astrophotography mostly from my apartment balcony.

Trial and error is the best practice here.Īnother good reason to get an altazimuth mount is that many times people want to do astrophotography from the backyard or balcony of the apartment and not travel somewhere for the dark skies. You will get the sense when is the object rotating less and you can do longer exposures.

It will create a red rectangle on the map so just zoom in to see it on the full screen and fast forward the time. You have to pick the telescope and the camera you want to use. Just find the object in the Stellarium and use the camera frame simulation. The easy way to find out how much and when is the object rotating is to use Stellarium. The rule of thumb is that if you photograph something close to the meridian, the rotation of the field is higher. In some cases, you can take more than 30s exposures. The altazimuth mount is not compensating for each sky movement, so if you track the object long enough, you will see that the object rotates. The exposure limit is caused by the field rotation. The 30s exposure is good enough to take some nice pictures even in medium-polluted skies. You are going to be limited to a 30 to 60s exposures depending on the position of the object on the sky. But it can be done with an altazimuth mount too. For astrophotography, it’s recommended to use equatorial mount because you can take long exposures with it.

Manual mounts can be upgraded with a step motor that tracks the object, and it is even cheaper, but you will have a hard time to find deep space objects on the sky with it. GoTo system will find every target automatically, and it will track the object during the shoot.
Telescope Mountįirst, we need the GoTo mount, not a manual one. This is the most expensive part of our budget astrophotography setup. dedication and a little bit of DIY skillīy cheap I mean adequate piece of equipment for least money possible for this purpose.Ultra Thin T-Ring to connect the camera to a telescope.
