150mm f/5 astrograph for astrophotography

 

Documentation is definitely a WIP

The mirror being used in this scope I got from ebay, you can find it here. The camera I used is small so I just went with a 45mm secondary mirror.

 

General hardware that you're going to need is M4 heatsets, M4 screws, M6 heatsets, M6 nuts, M6 screws, and a couple of M3 nuts and M3 screws (for the guide scope clamp).

The only part with captured nuts that you have to pause and place is the bottom OTA.

There are parts in the 3mf for using both an Omegon focuser and a GSO focuser, although I've only ever printed and used the Omegon one.

 

You'll also need carbon fiber tubes that have an OD of 17mm. I personally used the 17x13 for extra strength. You can get them here.

If you want to print it or DO print it and have any questions - feel free to send me a message on discord @ jb1gs and I'd be happy to help out. 

I've just had first light with this scope and it performed well, stars were tack sharp and round - I just have some tracking mount limitations and weirdness that I'm working through so I don't have any finished sample images yet like I do on my smaller astrograph Squat.


edit: got some images! The images attached to this posting are taken with this scope
