Size matters, but how?

Hello again! Talking about telescopes, is size important? Well, as always, it depends on what you want to do: Planetary or Deep Sky Objects (DSO) Some maths! This, like many other things, can be solved using maths. So let's define a couple of formulas Maximum magnifications: As the name says, it is the maximum magnifications you can reach with your telescope. For this we need to know the aperture of the telescope: maximum_mag = 2 * telescope_aperture  maximum_mag_newtonian = 1.8 * telescope_aperture I do the distinction between Newtonian telescopes and others because on  Newtonians the factor is more close to 1.8 to 2. Magnification with eyepiece/sensor: Different eyepieces/sensors give us different magnifications. For calculating these magnifications we just need to know the focal length of the telescope and, for eyepieces, the focal length of the eyepiece; for sensors, we need to know the length of the diagonal: magnifications_eyepiece = telescope_foca

Starting in Astrophotography

Image
Hello again! Recently I've seen the same question repeated a lot of times in the Weekly Ask Anything Thread in this subreddit , the question is: What do I need to get started on Astrophotography? Well, this might sound like an easy question with an easy response, but it is not. First of all, you need to decide which kind of Astrophotography you want to practice. There are two major categories: Deep Sky Objects (DSO) Planetary One may think that you only need a Telescope and a camera and that's all, but that's not true by any stretch. So let's start explaining the different categories and what needs each of them. Deep Sky Object Galaxies, Nebulae, Open Clusters... Everything that is outside of the Solar System is considered DSO. If you want to capture Andromeda Galaxy or the Orion's Nebula, this is your discipline. But also, take into account that this is, probably, the most expensive and frustrating branch of astrophotography. So what do you need for DS

Hello, Universe!

Hello, Universe! A typical Programming joke translated to the astronomy. My name is Yago and I'm from Spain. I know, this Blog can seem confusing, an English spoken Spanish blog with a French name... Chaotic! I'm creating this blog for various reasons, first of all, to share what I learn about Astrophotography with other people who are practicing it or are interested in it. Also, I do it to have a place to write what I learn and be able to review it later so I don't forget it. My idea about this blog is to post discoveries, the equipment I use/acquire, the processes I do in my images (I'm really bad on this), etc. I'll write in English because it is the common language on the net. About me? Well as I said, I'm Spaniard, I studied Computer Science and I'm working as a Software Engineer specialized in Functional Programming Languages. I started to get interested in Astronomy a couple of years ago, watching videos of QuantumFracture . I decided to acquire
