North American and Pelican Nebulae with Samhyang 135mm and QHY268C This is my first ever image capture with the excellent NINA software.  I used my widefield rig which consists of the Samyang 135mm lens and QHY268C OSC camera using an IDAS 2″ LP filter.The image set is a modest 18 x 180s exposures, all binned 1×1.  Pre-processed and processed in PixInsight and a few tweaks in Photoshop.

HaRGB A perennial favourite object to image in the summer and autumn months in the Northern Hemisphere.  I’ve imaged this target with multiple equipment combinations over the years.  For example, in One Shot Colour (OSC), in widefield and in very wide fieldAs part of the image I used my existing Ha dataset from 2018/2019 which consists of 48 x 600 second exposures.  I discuss capture of this image here. 48 x 600s Ha Image I then captured the RGB dataset in October 2021.  This image is my first image set that I captured using the excellent NINA (Nighttime Imaging “N” Astronomy) imaging software.  I captured four hours of RGB data through Astrodon 31mm E series Gen 2 filters binned at 1×1.  This consisted of 300 second exposures.  Seeing and transparency were not good but clear nights have been very infrequent in the UK in the past six months so I went for…

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.
