I have enjoyed taking wide-field images of the milky way with my camera and have even made a few attempts at time-lapse photography such as from the Grand Canyon this summer. Naturally, I have been limited to exposures in the range of 20-25 seconds before stars would start to trail. This is less of an issue from my home due to light pollution, however, from Mount Lemmon or other dark sites such as Portal I would enjoy taking longer exposures. One common way to track stars and take long exposures is to piggy back one's camera on a telescope, however, that has two disadvantages for me. One is that it requires far more set up and gear than a simple camera tripod, and two, it means that I can not observe an astronomical target through the telescope if my priority is framing a milky way image.
My first target, as it should be this time of year, was the constellation of Orion. The camera attaches to the Star Adventurer with a user supplied ball-head and the first lesson I learned was that everything needs to be tightened down securely! Not just to prevent a major disaster, but also to prevent the camera from slowly slipping/rotating during the exposure. Once I had everything snug, I took the picture below with a 14mm f/2.8 Rokinon manual lens at ISO 800 for 30 seconds. Click to enlarge (and ignore the lens flare at lower left from a neighbors security light!).
As the sensor was exposing, I remembered that Comet Lovejoy (C/2014 Q2) was moving up through Lepus and toward Orion. I grabbed my binoculars, found the comet easily and noted its location. I then zoomed in on the image I had just taken and BAM! there was the comet! Below is the same image and you will see at lower right that Comet Lovejoy is labelled.
Recent images of this comet have shown that its tail has been having a very interesting past few weeks, separating from the comet with a new tail growing in place of the previous- this article from Universe Today explain matters. I took another exposure with the ISO too high (3200) to see if I could detect any tail structure...sure enough I thought I could see hints of one, so I inverted the image, stretched things a little and sure enough, you can see a thin tail stretching to the NE in the image!
Finally, as long as I had the the heavy lens out I centered the Orion Nebula and took a 30 second image of that region, and below is the result.
All in all, pretty impressive results for night one, and remember that all the above are single shots, no stacking of images. Taking images with heavy lenses will likely require the optional counterweight kit that Sky-Watcher sells as it did seem that the mount would struggle at certain orientations. Also, while I stuck to 30 second exposures last night just to make sure the mount worked (I have it on some authority I ordered the first one in the US!), a more critical polar alignment is needed for me to take long exposures.
