From the album: Clusters
Ahh, the Double Cluster... I cropped the image down so the clusters would be right in the middle of the image. Just as beautiful as it is when viewed in the telescope where the stars brighten up the eyepiece and you get countless amount of stars in a nursery brighter and hotter than our sun I took this at ISO 400, an Exposure time of 20 seconds (Could have done 15 seconds to prevent trailing), lastly an aperture of F/3.5. This was taken Friday the 27th October 2017, facing North-West at around 19:18. P.S: I know this isn't exactly the Double Cluster people were expecting, -
From the album: Deep Sky
Taken in September 2015 with SW ED 80 and Trius SX26C. I was interested to see how a deep sky object would image during the glow of the "supermoon", so I picked a relatively bright object - the ET or Owl cluster (NGC 457). LIGHTS: 28 x 300s, BIAS: 50, DARKS: 30, FLATS: 40. Post processing in MAXIM DL and Photoshop CC. The stars outside the cluster were reduced by the PS plugin StarShrink. -

The Lagoon Nebula ( Messier 8, NGC 6523 ) in the constellation Sagittarius - by Mike O'Day ( https://500px.com/mikeoday ) The Laboon Nebula ( M8 ) is visible to the naked eye under dark skies from most latitudes except the far north. Seemingly covering an area about three times that of the full Moon, M8 actually covers an area somewhat greater than 110 light years and is around 4300 light years from Earth in the Sagittarius-Carina spiral arm of the Milkyway galaxy.

The Rosette Nebula and Cluster ( NGC 2237 and 2244 ) in the constellation Monoceros edit: updated 30th Dec with improved colour balance and slightly increased brightness ... ...... original: ( please click / tap on image to see larger and sharper ) Still a work-in-progress really... with only 10 x 4min exposures for the main 'lights' before the clouds came over. I will try to add some more data when the moon has gone I am still experimenting with how to get the best out of the D7500. With the very warm nights ( low to mid 20s all night ) the

The Rosette Star Cluster and Nebula ( NGC 2244 & 2237 ) ( please click / tap on image to see larger ) This is the Inverted B&W version buried in my previous post ( I quite liked the way the inverted B&W brings out the star cluster and so I thought it deserved its own thread )

edit: Processed in January from data captured in June and it has been pointed out to me that, as per the rules, this image can not be considered for the competition. .............. The Fighting Dragons of Ara ( NGC 6188 ) ( please click / tap on image to see larger ) Image details: This is an HDR image constructed from exposures ranging from 2 seconds to 240 seconds in length. The aim was to capture the faint stars and details in the nebula whilst at the same time maintaining colour in the bright stars without clipping the highlights. Plate Solution: Res

The Fighting Dragons of Ara ( NGC 6188 ) ( please click / tap on image to see larger ) The Fighting Dragons of Ara ( NGC 6188 ) Bright Nebula NGC 6188 and open cluster NGC 6193 are embedded 4,300 light years away in the Sagittarius arm of our Milky Way galaxy and can be seen with the naked eye south of Scorpius in the constellation of Ara. With powerful stellar winds and energetic ultra-violet radiation, massive stars sculpt the interstellar gas and dust of the nebula into wonderful shapes and cause the interstellar gas to brightly fluoresce.

A deep look at Omega Centauri ( NGC 5139 ) edit: re-processed from the original exposures - April 2018 ........ previous version: Omega Centauri ( please click / tap on image to see larger and much sharper ) This image is an attempt to look deeply into the mighty Omega Centauri star cluster and, by using HDR techniques, record as many of its faint members as possible whilst capturing and bringing out the subtle colours of the stars, including in the core.

Hi, I am doing an end of degree project on variable stars due next thursday and London's weather does not allow finish it. I was wondering if someone would do me the favour of observing the pulsating variable star V0460 Andromeda http://variablestars.net/stars/460/ in the Johnson R filter, for a period of 1 hour and 50 minutes? please? Thanks so much!

21st April: Re-processed to better show the colour of the fainter stars ... ....... Shimmering like a pearl to the naked eye, this open cluster of mostly young blue stars ( known as the "Pearl Cluster" ) is approximately 5500 light years from Earth and was discovered by Abbe Lacaille in 1752 from South Africa. This HDR image is constructed from 11 sets of exposures ranging from 1/4 sec ( to capture the centre of the brighter stars ) through to 240 seconds ( for the fainter stars of the Milky Way ). Total exposure time was around 5 hours. A Clus

Update: 3rd June Re-processed to remove slight magenta tint caused by the non-uniform removal of light pollution by the DBE process ( it was being fooled by the very bright image centre ).

Also known as the Theta Carinae Cluster, The Southen Pleiades is a very bright open cluster in the Carina constellation. It was discovered by Abbe Lacaille during his visit to South Africa in 1752. Containing around 60 stars, IC 2602 shines with an overall magnitude of 1.9 and its brightest member is Theta Carinae with a visual magnitude of 2.7. This cluster of young blue stars is relatively close to us at "only" 479 light years. 5 May 2018 The Southern Pleiades open star cluster ( IC 2602 ) in Carina ( please click / tap on image to see larger and sharper ) Image details

The Jewel Box ( NGC 4755 ) is an open cluster of mostly hot young blue-white stars that appears to the unaided eye as a bright 4th magnitude star close to the Southern Cross. Only visible from southern latitudes, the Jewel Box was first recorded by Nicolas Louis de Lacaille during his visit to South Africa in 1751 and was later described by Sir John Herschel as "a casket of variously coloured precious stones" - hence the name "Jewel Box".

gum 15 nebula Gum 15 and Open Cluster CR197 in Vela - a WIP
MikeODay posted a topic in Imaging - Deep Sky
Re-processed 3rd March 2018 - no luck so far getting any more data; I will try again when the moon goes away ....... With my unmodified D5300 DSLR, the HII nebula Gum 15 is barely brighter than the surrounding diffuse red glow that surrounds it and it all sits way down in the noise. I decided to share this small WIP version as I think it may be a while before I can get the data I need to impove it. This one has way too much noise ( and hence quite heavy noise reduction / smoothing ) as the detail is very faint and I needed a massive stretch to pull it out - more dat -

Alpha Persei Cluster in Perseus Nikon D5300 60 x 4 seconds 70mm @ f / 4.8 ISO 3200 20 darks, 20 offsets. One day I'll learn how to do flats. Seriously challenging conditions last night with high winds and a great deal of intermittent cloud, despite the forecast of clear skies. Nevertheless I'm quite happy with this
