Here is a test of the old 50mm f1.7 M lens stopped down to I think f/2.8? Not sure, it's two clicks slower than 1.7 I've never been any good doing that math in my head.
It's only a test because this is only 5 - 60s exposures of the core region of the Milky Way taken with the iOptron Skyguider pro.
Which brings me to another point: I've turned this Skyguider Pro into something rather fun. I'm calling it The Travelling Skyguider, where people can apply and have the unit shipped to them to use for 4 months before it is shipped to another person. The aim is for anyone wanting to learn astrophotgoraphy and may not have the means to buy a tracker or experience/gumption to dive head first into astrophotography with a full imaging setup right off the bat.
Currently open to North American applicants only, because I am broke and can't afford to ship it all over the world.
If you're curious, send me a message or if you know of someone, tell them to email
thetravellingskyguider@gmail.com and I will send them the documents and application details.
