Is 30mm guide scope enough?
With more sensitive (and more expensive) CCD or CMOS-based guiding cameras, as mentioned below, flyweight guide scopes with apertures as small as 30mm can work well when guiding images with short focal length refractors as the main scope.
What focal length should my guide scope be?
Most people suggest the guide pixel scale no more than 4 or 5 times that of your imaging scope. So with the 30mm guide scope you should be good up to say 600mm focal length (assuming your imaging camera has a pixel size around 3.8u).
Do I need a guide camera astrophotography?
Autoguiding is an essential part of any serious deep sky astrophotography rig. Whether you’re guiding with a guide scope or off-axis guider, you’ll need a guide camera to go with it.
What focal length should a guide scope be?
The field of view (FOV) should be wide enough so that you have a good variety of stars in the field to choose from. Guide scopes in the 50mm diameter range typically have a focal length of about 200mm, which is a practical FOV for many imaging setups.
Are Alt azimuth Mounts good for astrophotography?
If you own an Alt-Az mount, you most likely think “It cannot be used for deep sky astrophotography”. But that is not correct. It is possible to take wonderful deep sky images with an Alt-Az mount if you know how to do it and pick the right objects.
Can you do astrophotography with an AZ mount?
Is OAG better than guide scope?
You can think of an OAG as more of an accurate, guaranteed good autoguiding measure when compared to a guide scope. This comes at the cost of setup difficulty, but it is worth it when possible. When at all possible I prefer to use an OAG, and in some cases I have to use one.
What is a telescope autoguider?
An autoguider is an automatic electronic guidance tool used in astronomy to keep a telescope pointed precisely at an object being observed. This prevents the object from drifting across the field of view during long-exposures which would create a blurred or elongated image.
