OK time to drop the quality a little
.
I've had my 3" wobbletronic for a few months now and had great fun with it. Now its time to see what sort of images I can get from it. If I can get as good as the other images here I will be very impressed.
So for my first attempt at imaging I took a bullet camera and removed the lense, made a quick adaptor from a syringe and shoved it into the ep holder. I found the FOV of the camera to be much small than the ep's I have so I had to get Jupiter exactly in the middle of the FOV before putting the camera in. Focusing the camera also proved difficult, actually I never got a clear image from the camera.
I could get about 20secs of video before Jupiter went out of the FOV. After opening the video in Regisatx and pressing a few buttons at random (I have no idea what to do here I just followed the defaults) I came up with my first astrophotgraph
. Attached is a frame grab and the processed image. its no work of art but it is a start. You can't tell from the image but it is Jupiter :-) I'm impressed with the Registax software, very clever stuff.
After some advice from the good folks here I discovered I needed to reduce the exposure time as Jupiter was too bright. Given that the camera has no manual control at all this was not so easy. I ended up masking the scope so the amount of light entering the camera was reduced. This improved things a little but still a long way to go. The result of this is attached. I think you can just make out the bands, maybe with some better processing they would be more visible. I suspect reducing the light entering the scope is not quite the right thing to do.
Next I focused the camera on the moon first before pointing it to Jupiter. I was able to get a good focus on the moon and I could see the effect of the atmosphere wobbling/bluring the image. This also highlighted the need for a well aligned scope as finding Jupiter was not trivial. I haven't processed that image yet.
I also have a webcam which is now in peices and I'm goping to try K3CCDTools software to see what I can do with it. Might have to borrow a laptop from my housemate.
This is fun. I have an excuse to pull apart all my cameras!
Might need to stiffen up this mount too.
