HeartSoul-3- SadrAstro
Wide field on the Heart and Soul Nebulae, 5 hours and 45 minutes of HSO integration with Red Cat 51 Petzval Telescope, ASI6200mm pro 61-megapixel full-frame Mono camera, mount
Paramount MX 6, are 69 shots of which in Ha 17x300 seconds, in OIII 12x300 seconds and in SII 40x300 seconds, processing with Pixinsight and Photoshop.All data and shots were acquired with Sadr Astro Observatory. IC 1805 (also known as the Heart Nebula or by the abbreviation W4) is a nebula spread in association with an open cluster, visible in the constellation Cassiopeia, towards the border with the Giraffe.It can be detected about 6 degrees southeast of the star ε Cassiopeiae, but it can also be detected starting from the Perseus Double Cluster and moving about 4-5 degrees in a north-northeast direction; it pairs with another vast nebula, known as IC 1848. To be able to locate it, you need a telescope with a large diameter, not so much because of its size, since the nebula is quite large, but because of its weakness. A long-exposure photo or a CCD camera, on the other hand, reveals the object with some ease. The entire complex of nebulae visible in this area is circumpolar from most regions of the northern hemisphere; The best months for its observation are from October to April. It is a very large HII region, whose distance is estimated at 7500 light years from us; Its main feature is the presence of two large, apparently empty areas, of different sizes, which make the nebula similar to a "heart". Inside there is a system of small, loosely concentrated open clusters, responsible for the ionization of the nebula. The most notable of these is Melotte 15, which contains some stars about 50 times more massive than the Sun, plus others smaller and a microquasar ejected millions of years ago.
This and nearby IC 1848 form a large nebulous complex known as the W3/W4/W5 or "Heart and Soul" complex; the "heart" is IC 1805, while the "soul" is represented by IC 1848. IC 1848 (also known as the Soul Nebula, Embryo Nebula or by the abbreviation W5 for Westerhout 5) is a diffuse nebula associated with an open cluster of young and hot stars of great mass, visible in the constellation Cassiopeia, towards the border with the Giraffe. This is one of the areas where star formation is most active. The nebula can be detected about 8 degrees southeast of the star ε Cassiopeiae, but it can also be identified starting from the Perseus Double Cluster and moving about 5 degrees in a northeasterly direction; it pairs with another vast nebula, known as IC 1805. To be able to locate it, you need a telescope with a large diameter, not so much because of its size, since the nebula is quite large, but because of its weakness. A long-exposure photo or a CCD camera, on the other hand, reveals the object with some ease. The entire complex of nebulae visible in this area is circumpolar from most regions of the northern hemisphere; The best months for its observation are from October to April. It is a very large H II region, whose distance is estimated at 7600 light years from us; its gas is illuminated by the stars of some clusters and associations of nearby stars, among which Cr 33 and Cr 34 stand out, two very large but unconcentrated open clusters, formed by blue giant stars born from the gas of the nebula. The light is then re-emitted by the nebula in the red color typical of H-alpha hydrogen emission lines. Star formation is very active within the nebula.
