More than likely, but I like a challenge.
If this were easy, everyone would be doing it.
Basically what I have done is attached a telescope to the camera.
Of course the f number with camera lenses are not the same as with telescopes. They're still calculated the same in that:
N = f/D where f is the focal length and D is the diameter of that opening, but in telescopes we consider N to be the focal ratio.
How good will it be? Won't know until I try it out. The higher the magnification, the lower the level of light will be. Which is why when you look at
something with a 25mm eyepiece on the telescope it's bright, and a 9mm will zoom in on it, but it will look much dimmer to your eyes.
My first subject for this lens will be something easy: The Moon. It's very bright, fractions of a second shutter speed and I don't need a tracking
mount with that, unless I'm trying to do video with it.
Then I'll move on to something harder. Like Orion's Nebula or the Pleiades, but first I'll do it without the 2x converter, at 500mm.
I learned the hard way a long time ago about just buying a bunch of equipment and trying to go to town like a pro, when you've barely read page 1 of
the manual, hehehehe.
