I captured two ISS transits of The Sun on the weekend of 12-13th June 2021. Both images and videos were taken with my Lunt Systems T60Ha Hydrogen Alpha telescope and ASI174MM camera. ISS Transit at 15:05.14 on Saturday 12th June 2021 The transit above was not quite visible from my back yard and so I had to put all the gear into the car and drive to about three miles from where I live. I set up about 20 minutes early to ensure I was ready to capture the data for the image above. I was not quite located exactly where the ISS crossed the precise diameter of the sun – I was about 300m away! Yes, a very small change of position on the Earth’s surface really does make that much difference to the visible track of the ISS across the face of the sun. The ISS was about…

A selection of images I took with my C925 and ASI224MC.  Transparency was reasonably good but seeing was quite poor and the image was wobbly.  Each image is developed from a 5000 frame .ser file choosing the best 15% of frames as a result of the poor seeing.  The Moon is at a phase of 82% waxing gibbous and some nice shadows on the terminator. From my back yard observatory in Nottingham, UK.  Using Celestron C925 SCT telescope and ASI224MC colour high speed planetary camera.Telescope is at its native focal length of F10 for all these images since the seeing was much too unstable to use a Powermate or Barlow, even a x2 one woudl have been too much on this session.

The Leo Triplet is a popular and famous group of galaxies in the constellation of Leo, best viewed in late winter/early spring in the Northern Hemisphere. They are often imaged together like this as the triplet or as individual galaxies. They are located about 35 million light years away and consists of the Messier galaxies M66 (top left in the image), M65 (bottom left ) and to the right we have NGC 3628, commonly called The Hamburger Galaxy. The galaxies are easily visible in a small to mid-sized telescope as faint smudges in this isosceles triangular pattern. The galaxies are sometimes called the M66 Group but ask any astronomer and they will immediately know what you mean if you mention the Leo Triplet! Another famous galaxy group in Leo is the M96 group. The Leo Triplet Technical Details Image captured from my back yard observatory in Nottingham, UK on the…
