Hi Steve and welcome to SGL
The Celestron 130EQ you have is similar to my Sky-Watcher 130P. I have been delighted with mine as an instrument for celestial observation. The views are clear, and you can easily observe double stars, globular cluster etc. Although I would expect that mount to be a bit wobbly.
Unfortunately, I don't think it is a very good setup for beginning astrophotography. Apart from the wobbly mount, I don't think that you will be able to achieve enough inward focus with the focuser and a DSLR which will mean that you will need to use a Barlow lens. That will put the focal length to 1300mm F/10. You would require a large and expensive mount in order for it to track accurately enough.
So, you should get a DSLR but use it separately. That way you will have an observing rig and an imaging rig.
