Prime focus, and our spring will be pink…

Just had some time before sundown, so I went outside with my telescope again. First I aligned the finder scope with the main ocular at some rooftop maybe 100 meters away. Then I tried a camera instead of an eyepiece again, and after removing some distance ring from my T2 to 1,25″ adapter I got the camera into focus, but it was still borderline (the focuser was into the telescope all the way, and still it could have been sharper). Which means that I should get the 2 inch adapter as well, since it saves another distance which I’ll need to focus to infinity.

Here’s a picture, first with the normal 25mm lens on my E-M10 camera:

And then the same rooftop with the E-PL5 (same sensor as above) straight through the telescope, without any lens:

So it does work, though being able to focus from maybe 15 up to 100 meters is a tight “envelope”. Plus, as you can clearly see, the second photo is sharper on the right than on the left (or in the middle of the frame), which means that I’ll also have to “collimate” that ‘scope – which means I’ll have to align its two mirrors, which is a pretty standard procedure for Newtonian telescopes. With these you’ll have to align its smaller front mirror at least once, but the main and much bigger one fairly regularly. That’s what those screws on its back are for…

Another topic: Mitchie and Zuleikha like flowers and gardening. And when they saw this at Aldi’s today, they just had to get it:

These have to get in now, before the first frost. And then our spring will be pink…

Thanks for reading.

P.S.: silly me. Just realized that I can screw off the whole 1,25″ eyepiece holder. The 2″ part which remains has a T2 thread, in which the ยต43rds-T2-adapter fits. So if I attach this, the camera can be mounted right on top of it, and it should be able to focus to infinity just fine. I’ll try that tomorrow, because now there’s clouds only. Telescopes are pretty modular, which is cool.
