This wide-field image frames the prominent emission nebula IC 1396, at left, and the faint arcs of Sharpless 2-129 at right, in southern Cepheus. IC 1396 contains the dark Elephant Trunk Nebula at about the 3 o’clock position in the nebula. At the top edge of the nebula is the orange giant star Mu Cephei, aka Herschel’s Garnet Star. The dark nebula at top left is Barnard 169-70-71. The dark nebulas at the bottom of IC 1396 are B160, B162 and the snake-like B365. A small blue reflection nebula below and left of the Sharpless complex is VandenBurgh 140.

This is a blend of filtered and unfiltered shots, all with the William Optics RedCat 51mm astrographic refractor at its native f/5 and with the Canon EOS Ra: 6 x 8-minutes at ISO 1600 without the filter and 4 x 12-minutes at ISO 5000 with the Optolong L-Enhance filter, which reduces light by about 2 to 3 f-stops but really makes the H-alpha nebulas stand out. All stacked, aligned and blended in Photoshop. LENR employed on all frames on this warm summer night to ensure the most accurate dark frame subtraction of thermal noise but at the cost of doubling the capture time.

The North America Nebula and the Pelican Nebula 5-Panel Mosaic - Taken over 3 nights in Nov 2020. Full size image is 8724 x 6831 pixels, which was too big to save as a JPG in PSCS3! I never had that problem before. LoL. Four of the panels were about an hour exposure each and one had only 37 minutes. The last two panels were taken during a full moon. The equipment used included a QHY183c camera (20MP), an Optolong L-eNhance filter and a Televue TV-85 at F/5.6. Sharpcap 3.2 was used for acquisition and stacking.

ic410-60x180-qhy183c_-20C-g20-o100-lnh-85f5_6

3 hrs of 3 minute sub-images (60x180 sec) were used to generate this image of IC410 and the Tadpoles with Comet ATLAS moving through the field of view during the exposures. Metro area (Bortle 7-8 Red Zone) conditions, clear and transparent, 55F. Equipment: Televue TV-85, QHY183c camera, Optolong L-eNhance filter, and an Atlas EQ-G mount.

This is the central area of Cygnus and its bright Milky Way starcloud surrounded by red nebulosity. At left is the star Sadr (gamma Cygni) with the complex of nebulosity catalogued as IC 1318. At centre is the distinct Crescent Nebula, NGC 6888, a expanding nebula created by winds from a hot Wolf-Rayet star. At bottom left is the star cluster Messier 29, though looking a little lost in the rich starfields here. At top is the cluster IC 1311, looking more obvious than M29 but not observed visually and included in the NGC catalog. Odd. At far right are the large and loose star clusters NGC 6883 and NGC 6871, the latter an obvious binocular sight. To the left of Sadr is the small cluster NGC 6910. The dark nebulas B145 and LDN 862 are at right. The small emission nebula at bottom is Sharpless 2-104.

This is a stack of 6 x 6-minute exposures at ISO 1600 without a filter, blended with 8 x 12-minute exposures at ISO 3200 taken through the Optolong L-Enhance dual narrowband filter to really bring out the faint nebulosity. All were with the William Optics RedCat 51mm f/5 astrograph and red-sensitive Canon EOS Ra full-frame mirrorless camera.

Blending the two sets of exposures brings out the nebulosity while retaining the more natural colours in the stars and background sky. All stacked, aligned and blended in Photoshop CC. Taken from home in the wee hours of the morning of May 15/16, 2020 before dawn’s light began to wash out the sky.

The Eagle Nebula at top (aka M16) and the Swan Nebula (aka M17), straddling the Serpens-Sagittarius border. The star cluster below M17 is M18, while the small cluster above M16 is Trumpler 32. The Swan Nebula is also called the Omega or the Checkmark Nebula. The Eagle Nebula contains the dark towers called the Pillars of Creation made famous in the Hubble images.

This is a blend of a stack of 9 x 8-minutes at ISO 3200 through the Optolong L-eNhance dual-band nebula filter, with a stack of 6 x 5-minutes at ISO 800 with no filter, all through the SharpStar 94mm refractor at f/4.4 and with the Canon EOS Ra camera. I used the AstroHutech filter drawer/adapter to aid swapping out the filter. Autoguiding was with the MGEN3 stand-alone autoguider. All images stacked, aligned and blended with Photoshop.

I shot this set on June 14/15 on one short night a week before summer solstice from home at latitude 51° N, so the sky was never fully dark, making colour correction a challenge, resulting in a somewhat monochromatic look. In addition, the time to shoot was only 2 hours or so, limiting the number of sub-frames. Plus this field is low in the south from my latitude.

Also taken on a very warm +24° C night for my western Canadian location, all without darks or LENR thermal noise reduction, as a test, just with frame-to-frame dithering to reduce thermal speckling which was abundant on the filtered high-ISO shots. Stacking with a median stack mode eliminated most, though not all, of the speckling.

I don't often upload my astrophotography images, mainly because I'm a bit of a beginner and I've only been doing it for the last couple of years. In reality, that's probably less than 6 months due to the Northern Irish weather! Every now and again, I'll try and upload something space-related if you want. This shot was just under 3 hours of exposure time.

If anyone needs some online lessons in deep space photography, I can give them. I know the learning curve is pretty steep!

For the first time I can remember, we had an entire week of consecutive clear nights. No option but to make the most of it. So despite it being low on the northern horizon, I pointed my smaller refractor telescope at a well-known part of Cassiopeia.

There's a lot happening in this region of space. All the rusty orange-red is Hydrogen-alpha emission nebulosity; the bright blue is Oxygen-III emission nebula. At the bottom is the well-known Lobster-Claw nebula (Sh2-157); upper left is the Bubble Nebula (Sh2-162 or NGC 7635) - a giant molecular cloud being excited and pushed away by its central star; toward the upper right is a small bright emission nebula NGC7538 in neighbouring Cepheus surrounded by the Ha haze of Sh2-161.

I accumulated a total integration of 19 hours using a mixture of Optolong L-eNhance and IDAS NBZ dual-narrowband filters for the nebulae and Neodymium for the stars (so the colours are very realistic). In the process, the image became not just about the obvious bright glowing bits but also about the subtle veins of dark nebulae running through the Bubble and the large Y-shaped expanse in the upper third.

Whilst exploring in great detail, I stumbled across a rather fuzzy looking star just above the centre of the image, left of the top "claw" - with some research, it transpires this is HH-170, the first time I've spotted a HerbigâHaro object (a tiny reflection nebula, jets of partially ionized gas interacting with more gas and dust surrounding newly formed stars).

It was sufficiently low on the northern horizon that I had to abandon shooting for an hour each night while the neighbours' house got out the way. Shooting at near-full moon through the thickest part of the atmosphere made for a lot of light pollution which took some work removing in post. I look forward to reshooting throughout the season.

Much of the work with stacking and extracting Ha and OIII channels and fixing the star shapes and colours happened in PixInsight, but the final combination was performed in Affinity Photo for a dynamic precise control of how far the OIII intersected overlapping the Ha signal, most notable in the Lobster Claw.

This is the faint but large planetary nebula known as the Medusa Nebula, but officially Abell 21 or PK 205+14.1 in Gemini. It was discovered in 1955 and was once classified as a supernova remnant. The very sparse open cluster NGC 2395 is at upper right from the nebula.

The nebula is thought to be 4 light-years across and 1500 light-years away.

This is a blend of filtered and unfiltered exposures: a stack of 4 unfiltered at ISO 1600 for 8 minutes each, and a stack of 8 filtered shots at 10 minutes each and ISO 3200, through the Optolong L-Enhance filter.

The bright star near the center is Sadr, in the constellation Cygnus. Surrounding it in clouds of red H alpha is the Butterfly Nebula. The small Crescent Nebula (looks a bit like the Euro symbol) off to the top right is formed by a different process - a Wolf-Rayet star, WR-136, is in the last phase of its life and is shedding material in winds. These winds are running into gas that the star lost before it entered this giant phase, creating a shockwave.

Capturing the Orion Nebula well is difficult. The high dynamic range means that it is easy to either lose the dim details or blow out the bright regions. This was my first attempt at combining two different exposures to preserve more details. The first image is a combination of 300s exposures for the faint details and 5s exposures for the details in the bright core.

The Orion Nebula is about 1350 ly away from us and one of the few nebulae that are easily visible with the naked eye during good sky conditions.

Nesta foto, alguns dos ícones do céu noturno: a majestosa Nebulosa de Órion (M42), nebulosa mais brilhante do céu, podendo ser vista a olho nu, com intensa formação estelar; a Nebulosa da Cabeça de Cavalo (IC434) com esse nome devido a silhueta de um cavalo em seu centro; Nebulosa da chama (NGC2024), que brilha devido à radiação ultravioleta de estrelas jovens e quentes, que por trás de regiões escuras de poeira ionizam o gás ao seu redor, dando este formato de uma chama; e ainda as famosas Três Marias Alnitak, Alnilam e Mintaka. Essas estrelas sempre foram minha referência no céu desde criança... Cada uma delas é uma gigante azul muito maior que o sol.

In this photo, some of the icons of the night sky: the majestic Orion Nebula (M42), the brightest nebula in the sky, visible to the naked eye and a site of intense star formation; the Horsehead Nebula (IC 434), named for its horse-shaped silhouette at its center; and the Flame Nebula (NGC 2024), which glows due to ultraviolet radiation from young, hot stars. Hidden behind dark dust clouds, these stars ionize the surrounding gas, creating its flame-like appearance; and the famous Three Sisters—Alnitak, Alnilam, and Mintaka. These stars have always been my guiding lights in the sky since childhood. Each one is a massive blue giant, far larger than the Sun.

Do you see the alien skull? This is the Rosette Nebula, a region of atomic hydrogen that has been ionized (HII region) by the star cluster in the middle.

The plan was to take about 40 x 200s exposures resulting in over 2 hours of integration. However, a tree came out of nowhere and ruined all the best laid plans of mice and screwed up guiding in most of the photos. At the end only 7 images were usable resulting in just under 25 mins of data.

The structure is about 5000 ly away and 130 ly wide.
