Since my 45 day free trial ran out before I ever got around to really using it I decided to buy it for good reasons. One, it is a beast for astrophotography! Two, it runs natively in Linux which is a major plus for me since I mainly run Linux. I maintain Windows on my laptop for now only because I'm working out some kinks on getting autoguiding to work on Linux on my laptop.
This is my first attempt at PixInsight, and I can say I'm quite please, and proud of the final results. The comparison of these two images is quite a difference. I still have a ways to go to get better in PixInsight, but for a first attempt I couldn't be happier with the results.
These two images were created from the same exact data. I had a bit of an issue getting rid of the red blemish in the upper left corner of the PixInsight image. I think a bit of light bled through when I was shooting my dark frames which may have caused this since I forgot to cover the camera with a shirt like I usually do, which allowed light from my back porch to bleed through on the dark frames.
I'd also like to thank +Stuart Forman for helping me get started in PixInsight.

Tonight the moon will be the closest it has been in 18 years (since 1993). Perigee strikes again! Yes I know I recently made a post (last month) about the Moon in Perigee, but tonight, well tonight’s is a bit different. The moon is going to be even closer AND it’s going to be a FULL MOON. This event only happens roughly every 18 years. My previous post about the moon in Perigee will explain it a bit better, so click here to read it. If you have read it and/or know what I’m talking about then I will quickly just explain what the difference is tonight.
Tonight the moon will be in Perigee, because the Moon orbits the Earth in an elipse, Perigee happens once a month. Tonight’s Perigee is the closest the Moon has been to Earth since 1993, at a distance of 356577 km or 221566.675 mi. Last month on February 19th the moon was 358264 km or 222603.744 mi. That’s only about 1,687km or 1048.253 mi. closer, but it’s still a lot closer.
There are articles stating that the “SuperMoon” is going to cause hurricanes, earthquakes, volcanoes, and so on. These articles are misinformation on what is going to happen. The most that is going to be affected by this is the tides, and that will take a day or so to take affect. You might not even notice this difference.
I just wanted to quickly bring up this “SuperMoon” today in hopes to get you to step out and take a look up. It will be extremely huge if you catch it as it rises up over the horizon due to illusions and it being a bit closer.
Tonight is supposed to be clear where I live, so you can guess I’m going out with my telescope to view this event. I will post some pictures of the moon tomorrow if I get any decent shots of it worth showing off. If you go out and look at the Moon tonight, leave a comment and let me know if you could tell it’s any closer compared to any other Full Moon you’ve seen.
NASA has discovered a distant galaxy of blue stars that existed 480 million years after the big bang. The Hubble Space Telescope was pushed to it’s limits to find what is likely the most distant object ever seen in the universe. Based on the objects color astronomers believe the light from the object traveled 13.2 billion years to reach the Hubble, which is roughly 150 million years longer than the previous record holder. The age of the universe is approximately 13.7 billion years. This object is the furthest and the earliest that has been seen in the universe. In the picture to the left it appears as a very tiny red dot. Click picture for it to appear larger, or click here to read the NASA article
This object is thought to be 13.2 billion light-years away due to the objects colors. The object is a candidate galaxy because it’s still not confirmed if it is actually a galaxy or not. Whether it’s a galaxy or some other object will hopefully be confirmed once the James Webb Space Telescope (JWST)
The part about this story that I find so interesting is that this object they are seeing is actually much older than they are seeing with Hubble. This object could actually be much larger now than we can see, or on the other hand it could not even exist anymore. Basically due to how long it takes light from that distance to reach us it’s almost like we’re looking into the past. The Hubble Space Telescope is kind of like a time machine.
