The amateur-astronomical equipment used, Explorer Scientific F/7, 165mm Triplet APO refractor, a 0.75x focal reducer and ASI2600 CMOS color camera. All stars and galaxies were processed out.

The galaxy NGC 3938, lies at 30.7 megaparsec away, putting it at around 65 million light years from our planet. In 2017 a blue supergiant star, located in NGC 3938 went supernova and exploded with the mass of 50 suns in what Astronomers call the force of a Type 1C category supernova explosion! The amateur-astronomical equipment used, Explorer Scientific F/7, 165mm Triplet APO refractor, a 0.75x focal reducer and ASI2600 CMOS color camera. All stars and galaxies were processed out.

The amateur-astronomical equipment used, an Explorer Scientific ED165-FPL53 APO Triplet Refractor with Ohara FPL53 ED (Extra-Low-Dispersion) glass. Equatorial mount used, Sky-Watcher EQ8-R Pro, with a ZWO ASI2600 CMOS color camera. Polar alignment and guiding achieved with a QHY-Polemaster camera and plate solving (astrometry.net). Imaging software used, AstroPixel.

The Great Globular Cluster in Hercules, also referred to as Messier 13. The Hercules Globular Cluster is estimated to be over 11 billion years old and 6,800 parsecs from our planet, with a linear diameter of 145 light years. If you glance over to the right of M13, lies the galaxy NGC 6207 which is located around 30 million light years from Earth. The image was captured using 31 sub-frames at 60 second exposures each, with a camera temperature set to - 32.2 Celsius. The amatuer-astronomical equipment used, Explorer Scientific ED165-FPL53 APO Triplet Refractor, Sky-Watcher EQ8-R Pro mount, ZWO ASI2600 CMOS color camera, QHY-Polemaster camera for polar alignment and plate solving.

The Sunflower galaxy, image was captured using 9 sub-frames at 300 second exposures each. The instrument used, a 165 mm APO refractor and CMOS color camera. The gain was set a bit to high for this particular celestrial object, 224. The camera temperature was set at -29 Celsius. The mount used, a Sky-Watcher EQ8 R Pro, equatorial mount. Polar alignment was obtained using a QHY - Polemaster camera and plate solving for guiding.

Image reprocessed. Instruments used, Explorer Scientific ED165-FPL53 (FPL-53 ED Glass) Air-Spaced Triplet Refractor, and ASI2600 MC Pro color - CMOS camera. Polar alignment obtained using Plate Solver - Astrotortilla & SharpCap.

The globular cluster Messier 92, located 27, 000 light years from our planet, in the constellation Hercules. Messier 92 according to Nasa, contains 330,000 stars in total. The image was taken using seven sub-frames at 100 second exposures each, with a camera gain of 210. Instruments used, Explorer Scientific ED165-FPL53 Air-Spaced Triplet Refractor and ASI2600 MC Pro color - CMOS camera. Polar alignment obtained using Plate Solver - Astrotortilla & SharpCap, and syncing the mount and re-center target for image tracking.

The Splinter Galaxy, NGC 5907, located in the constellation Draco, is also known as the Knife Edge Galaxy, which lies at 40 million light years away from Earth. The image was captured using a 6.5 inch, apochromatic refractor and CMOS color camera, stacked using 16 sub-frames with an exposure of 100 second each. Camera temperature set at -28.4.

The image was taken using ten sub-frames at 100 second exposures each, with a gain set to 327 and camera temperature at -28.7 Celsius. The equipment used, an ES - ED 165mm APO refractor, Sky-Watcher EQ8-R Pro mount and ASI2600 color camera. Image processing software used Adobe Photoshop, GradientXTerminator Adobe plugin, Astro Pixel and calibrated frames.
