Am i doing something wrong

Postby rab3 » Tue May 12, 2015 7:51 pm

I have a Canon EOS 400d attached to my Meade 2090. I bought an eyepiece projector so as i could put various eyepieces in and see what difference it would make. my question is when i take a photo in daylight through the telescope if it is a fast shutter speed i get a image back, but if i take a picture with a slow shutter speed say 1 to 2 seconds the image comes back white, dont know if that is the norm or not in daylight, i have not tried it at night time as i am just starting out, any info on the eyepiece projection and how to start of with taking shot of the moon and planets would be a great help. totally new to all this, when i see what you guys can get with your cameras through the telescope, well amazing is an understatement. Thanks

Are you using the camera with a normal lens fitted to take pictures of the image projected by the telescope's eye piece? Or are you attaching the camera body with a T-Ring adapter to the eye piece? A picture of the set up might help.

The black image with a fast shutter might indicate an under exposure or an optical misalignment.

The white image from a slow shutter might indicate an over exposure or an out of focus image of the eye piece's exit pupil.

In the old days, the only thing needed in amateur astronomy, was a Mk-I human eyeball.

Applied to a 3-inch refractor or 6-inch reflector, to actually look through. And make observations.

But these days, the observations don't seem to matter. All that matters is this:

WHAT EQUIPMENT ARE YOU USING

Yeah, but without equipment, you'd just be staring up at stuff. ;)

I think you got it right, Sky.

Staring up at "stuff" in the sky, is nowadays not really important. I mean the "stuff" itself doesn't matter.

It's which eyepiece we're using to stare at the "stuff" with, that we must give all our thoughts to.

Apparently.

Well, you still need stuff to look up at, eyepiece or no, I just wish the clouds would disperse a bit. I got a tantalisingly good view of Saturn in the south last night with the naked eye. I was so tempted to set the Mak up, but it was late and I was very tired.
