Nova and Supernova

Supernova SN2020fqv in Galaxy NGC 4568

Here is a view of the Siamese Twins Galaxies, also known as the Butterfly Galaxies, located in the constellation Virgo. These galaxies are in the early phase of colliding and merging with each other. Also identified in this image is a new supernova designated SN2020fqv that was discovered on March 31, 2020 by the Zwicky Transient Facility. The magnitude of the supernova is about 15.5. The galaxies are about 60-million light years away from Earth.

Nova Cassiopeia 2021 Observation

Here is a view of the open cluster Messier 52 (M52) and a bright nova designated as Nova Cassiopeia 2021. This observation was done on May 17, 2021 with an estimated magnitude of 6.5.

Supernova SN2020hvp in Galaxy NGC 6118

Here is a shot of the galaxy NGC 6118, it is a grand design spiral galaxy located 83 million light-years away in the constellation Serpens. It measures roughly 110,000 light-years across; about the same as our own galaxy, the Milky Way. The magnitude of this galaxy is about 12.4. The "dot" in this image is a star that has gone supernova, designated SN2020hvp, inside that galaxy. Estimated magnitude in this image is 16.5. This supernova was discovered on April 21, 2020.
Tech Specs: Meade 12” LX-90, ZWO ASI071mc-Pro, 45 x 60 second exposures (Gain 200, Offset 65, Temp 5-degrees F), guided using a ZWO ASI290MC and Orion 60mm guide scope. Captured using Sequence Generator Pro and processed using PixInsight. Image date: May 25, 2020. Location: The Dark Side Observatory, Weatherly, PA, USA.

Supernova SN2020hvf in Galaxy NGC 3643

Here is a view of the galaxy NGC 3643 that shines with a magnitude of just 13.5, also in this view is supernova SN2020hvf, you can see how it outshines even the galactic core, impressive. This is a Type Ia supernova.
From Wikipedia: A type Ia supernova (read "type one-a") is a type of supernova that occurs in binary systems (two stars orbiting one another) in which one of the stars is a white dwarf. The other star can be anything from a giant star to an even smaller white dwarf.
Tech Specs: Meade 12” LX-90, ZWO ASI071mc-Pro, 44 x 60 second exposures, guided using a ZWO ASI290MC and Orion 60mm guide scope. Captured using Sequence Generator Pro and processed using PixInsight. Image date: May 25, 2020. Location: The Dark Side Observatory, Weatherly, PA, USA.

Supernova 2019ein in Galaxy NGC 5353

Here is an image of the supernova in galaxy NGC 5353, 110+ million light years away. This is an 11-minute stacked image of the supernova and surrounding area.
This is a type Ia supernova and are thought to be the result of the explosion of a carbon-oxygen white dwarf in a binary system either due to accretion from a donor or mergers. (ref: http://astronomy.swin.edu.au/cosmos/T/Type+Ia+Supernova)
Tech Specs: Sky-Watcher Esprit 120mm ED Triplet APO Refractor, Canon 6D, ISO 3200, 11 x 60 seconds (with darks and bias frames), guided using a ZWO ASI290MC and Orion 60mm guide scope. Image date: 30 June 2019. Location: The Dark Side Observatory in Weatherly, PA, USA.

SN 2020jfo in Messier 61

Here is a view of the relatively new supernova SN 2020jfo located in the beautiful spiral galaxy Messier 61 in the constellation Virgo. The left image was taken on May 13, 2020 showing the bright supernova, the image on the right was taken on April 1, 2019. Doing a quick comparison, it looks to be hovering at magnitude 14.
Tech Specs: Meade 12” LX-90, ZWO ASI071mc-Pro, 55 x 60 second exposures, guided using a ZWO ASI290MC and Orion 60mm guide scope. Captured using Sequence Generator Pro and processed using PixInsight. Image date: May 13, 2020. Location: The Dark Side Observatory, Weatherly, PA, USA.
