But.....It's not a great scope for learning Astro photography. If AP is your goal, get a short/fast, ED or fully apochromatic refractor. Something with a focal length of around 400mm or so.
The short focal length will be more forgiving of tracking errors and allow you to up and running taking photos much quicker.
Long focal length instruments need much more stable mounts as they magnify to a much great extent and are generally slower photographically so need even longer exposures which leads to even greater tracking errors.
The point...Start small and with little $, work your way up if your interest stays.
