Astrophotography telescope : Tutorial and tips for astronomy and astrophotography

  • Albireo : A so beautiful double star

Welcome to This website was created to share with you the best practices and tutorials on Astrophotography. You’ll learn how to choose the best telescope you need and also how you use it. You’ll find tutorials on image processing for planetary and deep sky imaging. You can also find reviews of the best astrophotography equipment: cameras, telescopes, mount, filters,…

I love astronomy since childhood and astrophotography is a new hobby for me when i bought my first telescope: a Newtonian Skywatcher 150/750 on a Neq3-2 mount. The mount has no GoTo and no Autoguiding, but has only a right ascension motor.

I read a lot of comments and reviews of people saying that with that mount it’ll not be possible to do Astrophotography of the Deep Sky because it’s not designed for that and because it’s a light mount and it can’t handle the Skywatcher 150/750.

The scope weights 4.5 Kilogram and the mount has a maximum load of 5 Kilogram. So if i add the finder scope and the camera the total weight will exceeds the maximum capacity of the mount.

And in astrophotography there’s a rule that the total weight of astrophotography equipment (telescope + adapter + camera + filters + finderscope) shouldn’t exceed 70% of the maximum load of the mount. So in my case it’s clear that I’m at 100%.

But with a precise and good balance, I was able to achieve a perfect stability of my astrophotography equipment and after a well polar alignment. I succeeded to photograph the beauty of the Deep Sky. Of course it’s not possible to pose longer than 60 seconds with no Autoguiding. But even so, I had very detailed and sharp images Star clusters, Open clusters, Galaxies and Nebula.

For some objects of the Deep Sky, poses of 30 seconds were sufficient to obtain a good result. You can see these images of the Orion Nebula (M42) of The Great Hercule Cluster (M13). Both of them were captured with a 30” seconds of pose. You can see how much detail I obtained.

The Skywatcher Telescope 150/750 is certainly the best beginner telescope for those who want to learn and start astrophotography. It’s easy to use, easy to collimate and the time required to cool the scope is very short compared to other telescopes like the Maksutov or Schimdt-Cassegrain.

Some of my pictures were selected and published in a famous Magazine, Facebook and Twitter pages.

For planetary imaging it’s best to have an astrophotography camera that means a dedicated camera for imaging the planets like ASI or ATIK. They are very sensitive and can capture a huge number of frames per seconds. But for my case I’m actually using a modified Webcam (Logitech C270). With a Barlow I had an excellent result on Jupiter, Mars, Saturn and the moon and its craters.

      Hi John, which software did you try to download and what’s the link that you used for ?

    Can you tell me how many frames for how long you captured these with the c270. Ive just ordered an adapter for it.

    1. hdryx

      It depends of the object, the conditions, the seeing, … But usually i capture between 3000 and 5000 frames.

    Hi, the adpater just came today. I’m just wondering if it’s usual for the image to appear somewhat blurry even when in the fullest focus? I’m going to try and capture Saturn when the clouds clear up. Also did you have to glue your webcam adapter to the webcam itself? Because it wouldn’t thread through. I’m gonna capture the video and stack it in registax. And use the wavelets of course.

      Hi, did you remove the lens of the Webcam before you put the adapter?
      In my case I was able to fix directly the adapter without any glue. I just screw it, I had to force it a little but it fits. I’ll make a picture of it.

  4. SaltyTea

    Yes, I removed the lens but in the process took off what held it in place

  5. SaltyTea

    Did you unscrew the lens or take the whole thing off?

    1. hdryx

      Yes I unscrewed the lens and removed it. I’ll send you tomorrow a picture of the Webcam.

    I’m honestly gob smacked how you got so much detail from it.
