Mirrorless Astrophotography - something different!

Ever since I got an entry level tracking mount in late 2025, my interest in astrophotography has grown and grown!

Having built up a range of Canon lenses over the years, mainly for bird and dragonfly photography, I am interested to see what I can get by pointing these lenses upwards at night.

I now have some results over a wide range of focal lengths, from an 8mm fisheye to a 500mm telephoto. Since the summer, I am using a new camera with these lenses - an astro modified Canon RP and, since the autumn, I have a better "GOTO" equatorial mount than the simpler tracking mount I started with.

I have started dabbling in the field of dual narrow band imaging, all with these lenses and the Canon RP.

For more info and some of my first images, see the new pages on my website:

  Mirrorless Astro  

I have also revisited some of my older untracked DSLR images of comets, eclipses etc, using some of the new processing tricks I have learnt this year.

For some examples, see below. Several more are on Mirrorless Astro, which also features a couple of pages on the equipment I have been using and my experiences with it.

Untracked image of Comet Lemmon 2025 A6 reprocessed. Note the two tails, with the blueish straight ion tail extending to the edge of the field of view of the 100mm lens.

Second and improved image of the Andromeda Galaxy, M31 using the Canon EF 500mm f4 lens with auto-guiding and tracking.

This image was derived by combining a normal RGB image with the hydrogen alpha emission line data from a "drop-in" narrow band filter.
