Making the most of clear skies

Cameras are certainly the hot thing at the moment in the world of astronomy, with several manufacturers bringing out new models, it seems, every five minutes.

These days, many models suit not just planetary but deep-sky imaging too, due to their ability to cool before the long exposure causes image degradation. This month Pete Lawrence reviews the ZWO ASI224MC-Cool colour camera, which supports long exposures for this very purpose. See how Pete got on in his review in the October issue.

Until apochromatic telescopes drop in price to a ridiculously low level, there will always be the trusty achromat as a good basic starter refractor.

Unlike apos, which have highly corrected optics, achromats still show a little chromatic aberration (colour fringing); but they are usually perfectly fine for the casual viewer. See how I got on with the Explore Scientific AR152 doublet achromat refractor in my review this month.

Finally, setting out the equipment each time you want to observe and rushing to take advantage of that clear patch of sky can often be frustrating if the sky doesn’t behave itself.

So this month Steve Richards takes a Tried and Tested look at the Pulsar 2.2m home observatory and what it has to offer. For one thing, having everything all ready and set up can be the difference between catching and using a clear patch of sky and wasting your time setting up, only to have it cloud over in the meantime.

See what Steve makes of the observatory and find out about all our reviews and much more by picking up the October issue of BBC Sky at Night Magazine, out 22 September!
