Question

I'm new to astronomy and I don't have a great deal of cash to spend. I currently have a 3" reflector telescope which I've had great fun with. I also have a Pentax DSLR which I've been using to take long exposure photos of various constellations (+ brighter deep sky objects such as the Orion nebula).

I've managed to take some surprisingly good photos of the moon and jupiter's moons combining my mobile phone with my telescope (which requires a very steady hand and alot of patience) but I'd really like a better way of taking photos. I'm wondering whether I should investigate getting an SLR mount to attach my Pentax to my scope, or whether to go for one of these webcam eyepeiece attachments. Any advice?

Explanation / Answer

If you already have a DSLR then a T-mount is pretty cheap and will give you steadier photos. The first issue you may hit is that you can only do short exposures unless you have a motorized mount.

I use a lens mount adapter on my Pentax K-x to attach a 1.25" barlow (http://www.amazon.com/gp/product/B00009X3UV/) and it works quit well for me.

But I also have a friend to does wonderful stuff using a Canon 20x zoom (non SLR) connected to a motorized mount.

One of the tricks to learn is image stacking. Registax (http://www.astronomie.be/registax/) for Windows does a very good job and is free. There are other apps for MacOS. This lets you combine multiple exposures to cancel out noise and to enhance your images.
