The Heart Nebula by Kevin Langford – Jan 2025

This is an absolutely stunning image of the Heart Nebula captured by member Kevin Langford over 2 nights on the 7th and 9th Jan 2025 from Bexley, Kent.

The Heart Nebula (also known as the Running Dog Nebula and Sharpless 2-190) is an emission nebula, 7,500 light-years away from Earth and located in the constellation Cassiopeia. The nebula spans almost 2 degrees in the sky, covering an area four times that of the diameter of the full moon. It was discovered by William Herschel on 3 November 1787.  

''The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered. The nebula's intense red output and its morphology are driven by the radiation emanating from a small group of hot stars near the nebula's center. This open cluster of stars, known as Collinder 26, Melotte 15, or IC 1805, contains a few bright stars nearly 50 times the mass of the Sun, and many more dim stars that are only a fraction of the Solar mass.''

Kevin acquired his image using:

ES 102ED APO, 0.7x focal reducer corrector, and EQ5 Pro.

ZWO ASI071, and Orion MMAG,L-eNhance filter.

7.5 Hrs of exposures.

Number of images taken 150 x 180sec.

Software used:

Sirilic to stack images.

Siril to processes image.

Affinity Photo 2 to finish.

IC 410 The Tadpole Nebula and IC 405 The Flaming Star Nebula by Neil Webster – 3rd Jan 2025

A superb image of IC 410 The Tadpole Nebula (left) and IC 405 The Flaming Star Nebula (right) by member Neil Webster taken on the 3rd Jan 2025.

''IC 410 is a cosmic cloud that looks like tadpoles swimming through the cosmos.

IC 410 is located 12,000 lightyears from Earth in the Auriga constellation, and is nicknamed the Tadpole Nebula because of the tadpole-shaped clouds of dark dust that appear to be swimming towards the centre.  The Tadpole Nebula is a region of ionised hydrogen gas spanning over 100 lightyears across that's carved and sculpted by streams of charged particles called stellar winds emanating from open star cluster NGC 1893.  NGC 1893 is about 4 million years old: the blink of an eye in cosmic terms.  The 'tadpoles' that give the nebula its nickname are dense streams of dust and gas about 10 lightyears long that may well be sites of star formation.'' Ref: https://www.skyatnightmagazine.com/astrophotography/nebulae/tadpole-nebula-ic-410

located near the emission nebula IC 410, is IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31).  IC 405 is an emission and reflection nebula that surrounds the bluish, irregular variable star AE Aurigae.

Neil acquired his image using a WO GT71 Apo, EQ6 R, ZWO ASI 294MC Pro Optolong L Enhance filter, Astro Essentials 50mm guide scope, and a ZWO ASI 290MM guide camera.

Processed using APT, PHD, Nebulosity and Photoshop.

58 x 240s Subs, 45 x 0.015s Flats/Bias.

Note: Neil suffered a power cut just before taking the Darks so noise reduction was applied liberally.

Elephant’s Trunk Nebula (IC1396A) – Oct 12th 2024 by Neil Webster

A super image of the Elephant's Trunk Nebula (IC1396A) taken by member Neil Webster on Oct 12th 2024.  The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region called IC 1396 which is located in the constellation Cepheus; about 2,400 light years away from Earth. The Elephant's Trunk Nebula is a small part of the much larger IC 1396 emission nebula and can be found on the Western side of the main object.

Neil acquired the image by using a WO GT71 Apo, EQ6 R, ZWO ASI 294MC, Optolong L Enhance filter, Astro Essentials 50mm Guide Scope, and ZWO ASI290MM guide camera.  Processed using APT, PHD, Nebulosity, PS (Camera Raw), and Star X Terminator.

Shears Green Junior School Cosmic Camp – 27th Sept 2024

On Friday 27th September 2024 several CMHASD members helped out at Shears Green Junior School Cosmic Camp. 

Chairman John Archer wrote ''First of all I really want to thank all of the team who supported our evening of outreach last Friday 27th.  Once again we attended Cosmic Camp at Shears Green Junior School and were greeted by an enthusiastic audience, most of whom managed to observe Saturn, as well as a number of deep sky objects. There were indoor activities run by Rita and Debra, and the pupils were treated to our slideshow of members’ aurora images. Outside there were a range of scopes – Dob’s, a refractor and also Smartscopes, ably demonstrated by our hardy team including Steve, Dave, Andy, Diane, Mike, Jim & co – thank you all so much for giving up your time and getting involved – it was a wonderful and eventually clear night''.

Below are 2 of the images taken by members whilst at the school that the children saw.

M31 by Dr Mike Rushton using a Dwarf II smartscope with no processing.  Stacked image of 200 x 10s exposures at gain 80.

M31 is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It is also known as The Andromeda Galaxy, Messier 31 and NGC 224. The galaxy is approximately 765 kpc (2.5 million light-years) from Earth. The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda.

M27 by Diane Clarke (with the help of Jim Burchell) taken using a Seestar S50. Stacked image of 224 x 10s exposures. Processed using Affinity Photo.

M27 (also known as the Dumbbell Nebula, Apple Core Nebula, Messier 27, and NGC 6853) is a planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, at a distance of about 1360 light-years. It was the first such nebula to be discovered, by Charles Messier in 1764. Ref:https://en.wikipedia.org/wiki/Dumbbell_Nebula.

The North America Nebula (NGC 7000) & the Pelican Nebula (IC 5070) by Neil Webster

Neil's first Deep Sky image for 18 months.......The North America Nebula & the Pelican Nebula and what a super image it is!

The North America Nebula (NGC 7000) is at the top and the Pelican Nebula (IC 5070) is at the bottom. 

The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to the star Deneb.  It is named the North America Nebula because its shape resembles North America.

''The Pelican Nebula (also known as IC 5070) is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. The Pelican Nebula is located nearby first magnitude star Deneb, and is divided from its more prominent neighbour, the North America Nebula, by a foreground molecular cloud filled with dark dust.'' Ref:https://en.wikipedia.org/wiki/Pelican_Nebula

Neil acquired his image on the 27th Sept 2024 using a WO GT71 apo, EQ6-R, ZWO ASI 294MC Pro, Optolong L-Enhance filter, Astro Essentials 50mm guide scope & ZWO ASI 290MM guide camera.

Processed in APT, PHD, Nebulosity, Photoshop and Star Xterminator

NGC 6992 & NGC 891 by Jim Burchell

Two excellent deep sky images taken by Jim Burchell on the 14th Sept 2024 of NGC 6992 and NGC 891 using his Seestar S50 smartcope.

The Veil Nebula is a cloud of heated, ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop a supernova remnant.  Sections of the Veil Nebula have their own individual names and catalogue identifiers and NGC6992 is a bright area in the Eastern Veil (also known as Caldwell 33) of the Veil Nebula

The image is made up of 138 x 10 second stacked images. Then processed in Snapseed.

 

''NGC 891 (also known as Caldwell 23, the Silver Sliver Galaxy, and the Outer Limits Galaxy) is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6, 1784.'' Ref:https://en.wikipedia.org/wiki/NGC_891

This image is made up of 48 x 10 sec stacked images. Then processed in Snapseed. Ref:

The Fireworks Galaxy by Terry Miles

A superb image of the Fireworks Galaxy also known as NGC6946 taken by member Terry Miles on the 10th Sept 2024 using his Seestar S50 smartscope despite some very annoying high thin clouds that would not just go away. 

''The Fireworks Galaxy, is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus. Its distance from Earth is about 25.2 million light-years.'' Ref:https://en.wikipedia.org/wiki/NGC_6946

The Veil Nebula by Kevin Langford

An absolutely stunning mosaic image of the Veil Nebula taken by member Kevin Langford from Bexley on the nights of the 11th & 12th August 2024.

The Veil Nebula is a cloud of heated, ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop a supernova remnant.

This is a 4 panel mosaic; with just 40 mins of data per panel. Kevin says it needs a lot more data to be added but we think it is fantastic already.
