Images at 400mm, stepping up to 1000mm should be a smooth process.When I first started using my Celestron Edge HD 11 telescope (2800mm), I found it difficult to star align my telescope mount and locate objects in the night sky using my original routine. This is because I was now looking at a very small area of the sky at once, and this leaves very little room for error in terms of pointing accuracy.Choosing a TelescopeThere are many telescopes to choose from, and they come in a seemingly endless amount of types and sizes. The main types of telescopes used for astrophotography are refractors, reflectors, SCT’s and RCs. Here are some examples of each type of telescope that I have personally used for astrophotography.Refractor: William Optics Zenithstar 73Newtonian Reflector: Orion 8″ Astrograph ReflectorSchmidt-Cassegrain: Celestron NexStar 8SERitchey-Chretien: iOptron Photron RC6It should come as no surprise that telescopes can be expensive, so you may want to look for used equipment to save some money starting out. A compact refractor telescope has many advantages, and it’s what I recommend for beginners. Being able to take a successful ‘first image’ is important during beginner astrophotography outings, as achieving a positive result is more likely to inspire you to push forward.A refractor telescope with a diameter of 80-100mm is considered to be ‘wide-field‘ in the deep-sky astrophotography world. These telescopes can capture most of the large deep-sky objects in the night sky within a single frame. Certain nebulae, such as the North America Nebula are so massive in apparent size, you may even need to create a mosaic to capture the entire thing. The William Optics RedCat 51 is an excellent choice for beginnersWide Field ViewsThe downside of a wide-field telescope is that small objects such as most galaxies will appear quite small within the
