M108 is a galaxy about 45 million light years away in the constellation of Ursa Major.  It is sometimes called the surfboard galaxy.   M108 in Ursa Major with TEC140 Technical Information Imaged from my backyard observatory in Nottingham, UK in April 2021 when M108 was almost directly overhead.  I used my TEC140 refractor and Atik 460 CCD camera with Astrodon E series Gen LRGB filters (1.25″).  There is almost 9.5 hours of data in this image consisting of:Lum > 42 x 300s; Red > 24 x 300s; Green > 24x300s; Blue 24 x 300sImage was captured using Sequence Generator Pro software and was guided using OAG on my MESU 200 mount.  Processed with PixInsight and Photoshop 2021 CC.I hope you like it!

M63 is a magnificent spiral galaxy located in the Northern constellation of Canes Venatici, about 30 million light years away.  The galaxy is a member of the M51 group.  There are lots of faint galaxies in the background. M63 – The Sunflower Galaxy Technical Data Imaged from my back yard observatory in Nottingham, UK over the nights of 4th and 5th of May 2021.  I used my TEC140 refractor and Atik 460 CCD camera with Astrodon LRGB filters.  I used off-axis guiding on my MESU200 mount.Integration is a total of nine hours comprised of:Luminance > 30 x 900s binned 1×1 ; Red > 22 x 300s 1×1 ; Green > 24 x 300s 1×1 ; Blue > 24 x 300s 1×1  to give a total of about 8.5 hours of integration time.  Captured with SGP pro and processed in Pixinsight and Photoshop CC.

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…

The Sun, 16 June 2021 at 13:10 UK time, Lunt 60Tha and ASI174MM This is a 10000 frame capture of the Sun with good seeing at 13:10 UK time in Nottingham. I used my Lunt 60Tha and my ASI174MM camera at 16-bit and 65 fps. The day was very hot – by UK standards – at about 28C and quite humid. I was able to use 92% of the frames which I stacked in Autostakkert. Post processing in IMppg and Photoshop CC. The image capture is a full disk and disk and proms are from the same capture.
