I am looking into making a hobby out of spectroscopy but don't exactly know where to start.
All I can really go off is a high school education of physics and the various reading that one usually does when looking into something new.
The main questions are, essentially;
1. What is the best spectrometry equipment for an amateur like myself?
I have little to no knowledge on all the necessary equipment, so any recommendations would be very much appreciated. For any suggestions, if you wouldn't mind giving a reason as to why you recommend a said product, I will take this information with great appreciation.
In terms of a camera, I've read that CCD monochrome cameras are the best. How does a DSLR rank against this though?
In terms of a telescope, should I be looking at one with a specific aperture range? If so, are there any other properties I should be looking at?
Is a grating better than a prism? Why?
What software is the most effective and easiest to use?
Do I need some sort of focusing device?
2. How do you collect spectral data using the technology?
Is it as simple as pointing at a star and recording the acquired data?
How long should I view the chosen star? Is it a photo or a video?
I would assume that these questions have been asked plenty of times, so any links to other forums which discuss the same questions and topics I am raising will be very helpful as well.
Any type of reply is welcome. As an amateur, anything is helpful.
Looking forward to discussing this with you all.
So, I have been testing three different kind of lasers, each one is supposed to be the "best" in each category or what you want to call it, the hotech and HG is almost the same, but whit the difference in how you lock it down.
The Catseye is very different in how it works.
I made a Youtube video of my thoughts
What do you think? which one do you use?
