How to reduce magnification and increase FOV of a camera attached to a telescope? I am a beginner in astronomy.
I have a Maksutov telescope (90mm/1250mm). Generally I do observation with a 25mm wide angle eyepiece, but sometimes due to light pollution I can't see many stars.
So I modified my webcam and converted to a telescope camera.
I can take detailed pictures of moon craters, but the FOV is very small. Is there any way to increase FOV? Can I set the camera on the eyepiece?
note: I am not expecting high quality DSLR-like images, but expecting more stars due to a longer exposure time.
You are using the webcam as an electronic eyepiece. People have been using various types of cameras as eyepiece for decades.
The reason for the small field of view is the small (1/4&quot;) sensor of the camera. Only a part of the actual field of view strikes the sensor. The field of view of your telescope will likely cover a 2&quot; eyepiece. You are putting a 1/4&quot; sensor into the middle of a 2&quot; circle. Tne sensor only sees the center portion of the total field of view.
Most use focal reducers in front of their cameras to increase the field of view of their electronic eyepieces.
I started electronic viewing twenty years ago with webcams and CCTV security cameras. I now use several Mallincam Astro cameras.
Google &quot;electronic eyepiece for telescope&quot; or &quot;electronic assisted astronomy&quot;. You will useful information once you get past all the advertising.
