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 field As 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…

A famous emission nebula in the Northern constellation of Cassiopeia, the Heart Nebula is a huge star forming region located about 8000 light years away, out in the Perseus Arm of our galaxy.  It is often imaged as a pair of nebulae alongside the Soul Nebula as the famous Heart and Soul Nebulae. I have imaged them together here  as well as The Soul nebula here, presented on its own.  It is also known as IC1805 and Sharpless S2-190. The Heart Nebula It is a beautiful nebula and I have even seen it portrayed on Valentine cards 🙂  Technical Details Imaged from my back yard in Nottingham, UK on 20 December 2020.  Seeing conditions and sky transparency were reasonable.  I used Takahashi FSQ85 refractor at native focal length and a QHY268C OSC CMOS camera.  I took 42 x 180s exposures and the data was captured with Sequence Generator Pro.  Processed…

The Soul Nebula – IC1848 The Soul Nebula is a large emission nebula in the constellation of Cassiopeia. It is commonly imaged with the nearby Heart Nebula as a nebula pair, not unsurprisingly called the Heart and Soul Nebulae such as my rendition here. The Soul Nebula is a vast star forming region and is located about 7000 light years away, in the Perseus Arm of our galaxy, outward from the core. It is sometimes called the baby nebula because it resembles a baby! Technical Data Imaged with my Takahashi FSQ85 refractor at its native focal length and I used my QHY268C colour camera on MESU 200 mount using off-axis guiding. The mage comprises 42 x 3 minute exposures to give a total integration time of just over two hours. It could use some more data, especially some Ha data to bring put more detail in the nebula. Seeing and…

IC1396 Elephant Trunk Nebula I have imaged IC1396 before.  It passes directly overhead at my location in Nottingham, UK.Imaged here on 14-15 October 2020 with FSQ85 refractor and QHY268C OSC camera on MESU 200 mount.A total of 55 x 240s exposures.  Developed in PixInsight and Photoshop CC.  Image capture with Sequence Generator Pro.
