The McWetlog: Gearing up for astrophotography. All the positive feedback I’ve received for my recent attempts at lunar photography have made me more enthusiastic than ever about getting into astrophotography.

The McWetlog: Gearing up for astrophotography

I’ve already got a few books on the subject; truth be told, there’s a bit of a learning curve. It’s going to take me a while to get good at this. And that’s not a bad thing, because astrophotography can be awfully expensive: it’s going to take me a while to assemble all the equipment required for a basic astrophotography rig that can do more than just photograph the Moon. I’ve already got two main pieces of equipment. I have a telescope geared towards astrophotographers: an 80mm Sky-Watcher Equinox apochromatic refractor, with really good colour correction (as far as I can tell) and a short (500mm, f/6.25) focal length. So, what else do I need? The first piece of equipment I’m likely to get is a Televue Powermate. . The one generating the most buzz is Orion’s inexpensive $280 (U.S.) autoguider.

Astrophotography - Guiding a Telescope for Imaging

The deep-sky images look so exquisite with their masses of detail and perfectly round, pinpoint stars. We know they didn't come easily. Impressive celestial photography is a lot more feasible for amateurs now than it was a generation ago. But good results still require a willingness to learn the intricacies of cameras, focusing techniques, exposure times, films, and miscellaneous equipment.

In particular, taking deep-sky pictures requires a skill that's involved in no other kind of photography: guiding on a star. To get a sharp image from a long exposure, you must keep a guidestar centered on cross hairs for the entire time the shutter is open -- from a few minutes to an hour or more. No telescope drive, no matter how well made, can eliminate the need for guiding.

The aiming corrections required are so tiny -- just a few arcseconds -- that you cannot push the telescope by hand. Russell Croman Astrophotography. 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 for Astrophotography

Telescopes reveal fainter objects than can be seen with the eye because they gather more photons than the eye can gather. Smaller details can be seen because they also magnify objects. The nomenclature used to describe telescopes and camera lenses can sometimes be confusing. Telescopes are usually talked about in terms of aperture, while camera lenses are usually talked about in terms of focal length.

Telescopes and camera lenses have three main numerical attributes that we are concerned with in describing them: Aperture - The aperture is the size of opening in the telescope through which the lens or mirror gathers light.
