More long exposure images.

Long exposures with a mamouth telescope....

Lastnight, I was invited to observe the night sky with a new friend of mine named Wayne. I jumped at the chance, as I love all things photography. Little did I know just how mind blowing this night would be. Please take a moment and check out his site, HERE, and look at his awesome images before returning back here.

Wayne had informed me about his “cameras" before. These cameras are unlike anything that I have ever come across. They do not look like cameras at all. These computer operated sensors attach to his giant telescope, and record, over time, what the telescope is pointed at. Long exposures are requried most of the time due to faint light sources of objects very far away. This requires that his telescope “track” the object that is being photographed. This is done, via more computers and a vast knowledge base of both the night sky, and the operating systems of the necessary equipment. Lucky for us Wayne has both.

The digital “super cameras” that are designed to image the night sky through a telescope require cooling systems, capture images in black and white, and come with a steep learning curve. Wayne shoots his images in a series of many. By using different colored filters (red, blue, and green) he gets “color” images. Let me just say that one must really want to take amazing images to go through all of this work.

However, these super digital cameras were not the evenings “event cameras”, as Wayne decided to go with a new Nikon digital SLR for taking long exposure images through his gigantic telescope. This was the first time that Wayne would be attaching his Nikon digital SLR to his telescope, and we were curious about how they might turn out. Would this set up even work? How would the focusing work, and what settings should one even use for this image process? Great questions, simple method for finding out the answers. We would try, and see what we get.

How is this? This image of the Orion Nebula was one of the evenings first images. Not bad, eh? Way to go Wayne!

The above image was at iso 200, taken for about 3 or 4 minutes, with the telescope locked on (or tracking) the nebula.

The night was spent looking back in time, through his telescope, and looking at objects that I never though I would see with mine own eyes. I saw Saturn through the telescope, so good infact that it looked like a fake cut out. The rings were visable as was the shaddow of the rings on the planet itself. We saw some of Saturns moons as well, and I enjoyed this paticular evening like none other.

A very large thanks goes out to Wayne for inviting me and working feverishly through the night so that I could see the sky. I am so thankful, and I will be forever anxious to return.
