Jupiter and Saturn are visible all night and many will want to take the opportunity to image these giant planets. Trying to get a small planetary image onto the centre of an imaging camera’s sensor can be difficult. You can move the telescope around tring to find the planets, or you can centre it in…
The effects of image tilt can ruin a great astrophoto. Image tilt (or image plane tilt) happens when an area towards the edge of the field exhibits out-of-focus or imperfect star images and is caused by the image sensor not being pefectly perpendicular to the light path. A mis-aligned focuser tube, flattener/corrector lenses, extension adaptors,…

Its hard to believe that a year has gone by since Venus seemed to be around for ages and was riding high in our evening sky during the late winter and spring months. This year, after its superior conjunction on March 25th 2021, Venus will once again start to become part of our evening sky…
Having multiple eyepieces at your telescope means you can swap between them to get different (more or less magnified) views of the Moon, planets and deep sky objects. However you have to think about where you are going to safely place the eyepieces when not in use. You also have to identify the eyepiece you…
Barlow lenses are a very useful addition to any visual observer or Lunar/planetary imagers’ “tool-kit”. If you have a set of eyepieces, by using a barlow you can immediately expand the magnification range that they offer. For a Solar system imager you can increase the image scale so the target is larger on the camera…
