Telescopes for Astrophotography As with picking a camera, picking the best telescope for your needs will depend on a number of different factors: Telescope Attributes - Telescopes are designed to gather light and bring it to focus so that the image can be examined in detail with an eyepiece, or recorded on film or with a digital camera. Telescopes reveal fainter objects than can be seen with the eye because they gather more photons than the eye can gather. How to Shoot the Night Sky (Introduction to Astrophotography) The following post on photographing the night sky is by jgomez65 – one of dPS’s forum members. Several people asked me to post a simple tutorial on how I took some night sky pictures. I am not an astrophotographer in any way, shape or form, nor do I have any expensive equipment. I simply read several tutorials, picked a dark spot on the beach and tried to do my best.

Astronomical CCD & Night Vision Devices There are tradeoffs in choosing the parts of a system to do this. OTA Optical Tube Assembly 24 April 2005 - The KStar Telescope seems ideal for this application and probably was designed for the Air Force to do just this. It has a 5 degree FOV and uses spherical mirrors (much lower in cost than any thing but a flat mirror) and has an adjustable f number (just the thing to match the CCD array to the seeing conditins.

Tips for Getting Proper Exposure for Night Photography Exposure settings for this shot: Shutter speed of 4 seconds; aperture at f/5.6; ISO 400. Night photography can be much more rewarding than photography during the day. Because everything looks different at night, you don’t need to go somewhere exotic to get great pictures. Bridges, attractions, and buildings are usually brightly lit at night, and places that might seem rather pedestrian during the day – can make stellar photography subjects at night. Further, you can take your time when photographing at night, more so than during the day.

PHD Guiding Basic Use and Troubleshooting - Imaging - Tips, Tricks and Techniques Pleas for help with PHD guiding seem to come up more often than almost other imaging topic. I make no claims to be the ultimate expert on the subject, but I have travelled some way along the road from guiding failure to success, and so I thought it might be good to share a few pointers I've picked up along the way. (By failure I mean I was getting one 1 minute exposure out of every five where the stars were slightly less egg-shaped than the rest. By success I mean I now discard one 10 minute exposure out of every thirty due to a guiding issue).

Beginners Tips for Night Sky and Star Photography Star Photography My favorite type of personal photography is taking night shots of the stars (long exposure pictures). I am often busy shooting pictures of people at weddings, or apartments, or models, and it’s important for me to make sure I take pictures for fun regularly.

Photographing Stars Using a Kit Lens Looking at a starry sky while sitting in the open is always a soothing experience, but shooting those stars is a much better one. Have you seen those amazing starry skies and Milky Way photographs from professional photographers and wondered how to do this yourself but never tried it because you thought you did not have the proper equipment? Let me tell you, “You were wrong”. If you own a normal DSLR camera and are interested in shooting stars (and the Milky Way), you can do this with your kit lens. I will explain the whole process step by step in the easiest possible way, so that even if you do not have much technical knowledge, you can understand and implement this method. Basics of star photography

Focus Masks Focus Masks Scheiner and Hartmann Masks Bringing a telescope to sharp focus at high magnification can be a real trial. An experienced visual observer will be constantly manipulating the focus. This is not an option with CCD imaging since you must set the system at optimum focus and then collect your frames. A focus mask is one way around this problem. How to Shoot a Star Trails Selfie There are times when planning and patience can result in a killer shot. This nighttime star trails selfie (above) that I captured in the Canadian Rockies was one of those times. I’d planned to shoot star trails over Mount Rundle and the town of Banff, Alberta while hopefully capturing reflections in Vermillion Lake, surrounded by melting ice. My initial vision was for a completely cloudless sky, but the small yet persistent low clouds ended up adding an ethereal quality to the shot I hadn’t expected. When I looked back at my first 30 second exposure, I knew right away that this shot had some potential. All I had to do was set things up properly and then play the waiting game.

Secret of the Hartmann Mask Secret of the Hartmann Mask... Revealed! Submitted: Tuesday, 5th April 2005 by Paul Russell Mike PMed me the other day and asked if I’d do an article on how to make a Hartmann Mask. This was a good thing as it got me off my backside during the days of my holiday, once I finished my books that is. :) So I thought while I was at it I’d do a review of the effectiveness of different hole patterns just to see which ones worked the best. The results quite surprised me.

If you are using a telescope at high power or are doing photography, you will need to have a telescope that “follows” them. The Ultimate Guide to Shooting Milky Way Photography With the low light capabilities of digital cameras drastically increasing in recent years, Milky Way photography is booming in popularity.
