My beloved pet of more than 14 years died some weeks back, and in a deep well of sadness and depression, I decided to treat myself and hopefully give myself something to keep my mind off my loss. I bought an ASI385MC camera and decided to get back into amateur astronomy, which is something I do truly miss. This is one of my first efforts with it - a timelapse using ZWO's 2.8mm - 12mm F1.4 CS lens. Note that this lens with this camera DOES produce considerable vignetting unless you're close to the telephoto limit, which is what I did. I expect this is somewhere between 8mm and 10mm. Also, when using this lens, you really need to remember to set the iris fully open, which can easily be overlooked and can really kill your low light performance.
This video contains A LOT of "UFO" type objects, by which I mean objects I do not have an immediate explanation of. For sure, there are MANY satellite passes, and some objects I believe to be "tumblers" (objects spinning in orbit, creating pulsing or flashing reflected sunlight effects). There is also the occasional meteorite streak or bit of space junk burning on re-entry. Near the end, The Andromeda Galaxy (M31) and The Pleiades (M45) make a nice cameo appearance. The bands of the Milky Way are bloody gorgeous in this.
And for those of you who are pedantic, boss level amateur or professional astronomers, yes, I did not use a dark frame nor did I use a flat frame. Still getting my head around how to do that and I had just gotten the camera. It'll happen in time. Technically I could even remaster this video with such things at a later date, though I'd rather just do a full reshoot with my improved techniques that I've learned in the time I've owned the camera.
Anyway, enjoy! And feel free to ask questions or make some commentary.
Much more to follow!
