FINDING THE NORTH STAR
FOR THE equatorial mount to work it has to be calibrated
by lining it up with the North Star – Polaris. The mount will
then rotate at the rate and orientation of the Earth, allowing
pin-sharp star shots with longer shutter speeds, which will
make them brighter and less noisy than pushing up the ISO.

makeshift red dot
sight and places
it along the
barrel of his
telescope and
adjusts the
setup by eye
until it’s spot-on,
though he said
even if it’s a bit
out it shouldn’t
matter much.EXPERT INSIGHT
SEQUATOR FREE
SOFTWARE
CHRIS USED Sequator
software to stack the best 15
Raw files he shot of the Orion
Nebula. Layering up several
images helps build up deep
tones and rich colours. The
program also allows you to
add a blank frame to reduce
noise, and images to reduce
vignetting, as well as a whole
host of other features. If you
fancy giving it a go yourself it’s
worth installing Sequator – it’s
free to download and use. Go

Canon EOS Ra
THE EOS Ra is a new mirrorless version of the
30Mp EOS R, but with a modded Infrared filter,
making it four times more sensitive to Hydrogen
Alpha (HA) light – for capturing the reddish tint of
nebula. It also has a 30x Live View magnification
to make it easy to focus on the stars with the LCD
screen and can essentially let you see in pitch
black conditions (full test of the Ra on page 100).
