I'll bite, what is the purpose of a vixen rail. I googled it and found a simple rail but could not figure out what the purpose of having it is. As I tend to do star trails and astro-photography I'm interested.
A Vixen Rail is one of the most common connectors of a telescope to a mount,
such as GEM.When you begin shopping for Astrophotography Equipment, you get caught in the unstoppable pull of a black hole drawing you into the acquisition and use of more and more expensive equipment to collect those faint and more difficult images in the Universe.
So, although shooting Star Trails is fun and seems innocent enough, it can lead to more sophisticated German Equatorial Mounts, and imaging Telescopes, connected by Vixen Rails.
My own experience was laying back in a lounge chair in heavy winter insulated clothing manually clicking images to make a Star Trails presentation. That lead to an innocent enough device called an Intervalometer to do timed releases of the shutter. In my early stages, it also lead to capturing Orion's Belt crossing in the developing Southern aimed Star Trail. I was unaware I was even capturing Orion until Bloke pointed it out to me.
That lead to me getting out a more powerful spotting scope and over a few nights I resolved a very tiny Orion's Nebula once I learned where it was. I wanted more.
I wanted to be able to actually Photograph The Great Orion's Nebula.
My processes are to determine what it is drawing my interest. Justify the means in my own head why it is worth pursuit. Find the means to get there, and the equipment present or needed. Then research and choose the avenue I will get there by observing how others have gotten where I'd like to eventually go. Once the research is done, slap the cash on the barrel head, and learn how to use the newly acquired equipment. (And staying absolutely determined to succeed in the endeavor. No matter what pitfalls come my way.)
So the innocent joy of Star Trails can, and does, lead to Vixen Rails.
I blame The Great Orion Nebula. As a hunter myself, I was determined to join in the pursuit of the incredible wonders to be found in Space. I chose to pursue Nebula, so I focused my equipment toward that end.
Deep Space Imaging, Nebula. The incredible end result we can observe in our narrow window of life on Earth.
So what will you decide to pursue?
Star Trails lead to Vixen Rails...
