We're just a couple of days from closest approach of Comet 46P/Wirtanen. Comet 46P/Wirtanen is a small short-period comet with a current orbital period of 5.4 years. This happens to be a favorable pass for us. If you get clear weather, get out and observe it with binoculars. December 13 to the end of the […]
We're heading into late fall and winter now, so the usual Michigan Nebula will be upon us for about 95% of the next 5 months. I hope we get more than a handful of clear nights during that time, but that is about what we usually get. A handful. In the meantime, we'll attempt to […]
The new observatory was completed on August 22, 2018. It is a 10x10 building with a powered roof. The 10" f/8 RC is installed again, and ready to be used. Here is a time lapse of the 3 day build. https://www.youtube.com/watch?v=fyWEcFgOPVE
As many of you know, when it comes to capturing astrophotography images, I tend to do things “the hard way” more often than I should. This includes everything from a manual 3-star alignment to carrying my astrophotography gear in and out of the garage night after night. It’s because I’m old-school. When I started deep-sky […]
I’ve recently had a chance to review the Optolong L-Pro filter (2 types) for astrophotography from my light polluted backyard in the city. Unlike many of the filters I used in the past, the L-Pro is suitable for both stock and astro-modified DSLR cameras. (It includes a UV/IR block). I've always had trouble collecting images […]
Over the past 8 years, I’ve had the pleasure of using a number of telescope mounts for astrophotography. Some of them were substantial imaging platforms that included features such as autoguiding and periodic error correction (PEC), while others simply tracked the night sky at sidereal rate in a compact and portable package. The payload capacity […]
Recently analyzed data from NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has revealed water locked inside the clays that make up its scientific target, the asteroid Bennu.
For the second time in history, a human-made object has reached the space between the stars. NASA’s Voyager 2 probe now has exited the heliosphere – the protective bubble of particles and magnetic fields created by the Sun.
Humanity’s search for signs of extraterrestrial intelligence has been underway, in one form or another, for decades. But how much searching have we really done? The post Searching for Alien Needles in the Cosmic Haystack appeared first on Sky & Telescope.
The NASA spacecraft detected signs of hydrated minerals on Bennu's surface, suggesting that the asteroid's larger parent body once hosted liquid water. The post Osiris-REX Finds Hints of Past Water on Asteroid Bennu appeared first on Sky & Telescope.
My own Hubble View! These galaxies lie between 10 to 50 million light years away. How many galaxies do you see?A pretty tricky part of the sky to image, really. You're utilizing almost your entire field of view with an 80mm scope, so dealing with all that comes with wide-field. This is the best iteration […]
A nice clear night last night until around 12:30 when clouds rolled in. Managed to get this image of the lovely M51 Whirlpool galaxy. It lies around 23 million light years away and it is interacting with a smaller galaxy (yellow~ish bulge to the left). Three supernova (star explosions) have been detected in this galaxy […]
The spring brings out some great galaxies. This is the first iteration of a long-term project I'll be working on with respect to these two galaxies.M81 is on the right, lies around 11.7 million light years away and harbors around 250 billion stars. M82, on the left, is also called the "Cigar Galaxy" lies at […]
