From the album: Deep Sky Imaging
The Rosette Nebula is a large spherical Hydrogen Alpha region located in the constellation Monoceros. The cluster and nebula lie at a distance of some 5,000 light-years from Earth and is roughly 130 light years in diameter. The open cluster NGC 2244 is closely associated with the nebulosity being the stars of the cluster which have been formed from the nebula's matter. The complex has the following NGC designations: NGC 2237 – Part of the nebulous region (Also used to denote whole nebula) NGC 2238, NGC 2239 & NGC 2246 – Part of the nebulous region NGC 2244 – The open cluster within the nebula This images total exposure time was 7 hours and 40 minutes, consisting of 15 x 600 second 7nm narrowband H-Alpha subs for the luminance channel and 15 x 180 second red, 15 x 300 second green and 19 x 600 second blue subs for the color data... color data was exposed during a full moon. Taken through a 80mm Refractor @ f6.25, on a hypertuned CGEM mount with QHY268M camera.© Mariusz Goralski

This is the SHO result of my first imaging object with the cooled Canon 40D. Through out the imaging, the camera failed a number of times due to condensation buildup inside and so this is a result of two different 40D bodies and sensors. I captured some HAlpha data with the originally cooled 40D before it failed and the second half of the HAlpha, OIII and SII are captured with the second modded and cooled 40D Exposures: SII: 30x1200s HII: 30x600s OIII: 30x900s ISO1600 Telescope: BOSMA Beta RE Focal length: 500mm© Mariusz Goralski

Taken early Monday morning. Most widefields of the Rosette include the Cone area but I went the other way to included Sh2-280 and Sh2-282. Wanted Sh2-283 as well but does'nt quite get there on the Samyang 135mm. Just 8x600secs Atik 383L, Samyang 135mm @ f/2 with an Astrodon 5nm Ha filter.

Just got in from my second time out with my scope and successfully found the Rosette nebula, NGC 2237. I'm trying to better my navigation so I spent some of the night gazing but I found that finding the nebula was fairly easy once I got the stars right. Low light pollution where I was at allowed me to see some fairly dim stars and I got to it within a few minutes. Being the first one that I've seen, I couldn't help but think "How will I know that I found it?" but the nice, bright cluster was quite obvious haha. I have a nexstar 8se and was using the 25mm ep that came with it, and I feel that this was fine, but I've read about some people going up to 40mm; what is your preference? I'm looking out for my next ep.

Hi, I would really appreciate some feedback/advice on the following. A few nights ago I took 45 x 300s subs of the Rosette Nebula at ISO800 with a modded 700d Canon DSLR through a Altair Wave ED80. I've stacked the image with 30 darks, 30 bias, no flats (I have a plano which, apart from the extreme edges seems to handle any vignetting) and had a go at processing in photoshop. I live between Leeds & Wakefield so skies are very light polluted but tried to reduce the effects by using a Hutech IDAS LP filter. I started image capture about 9pm so the Rosette Nebula was relatively low in the sky although some captures were taken much later when it has well above the horizon. After stacking I had some data but a lot less than I was expecting and really struggled to bring out any detail on Photoshop. The questions I have are: 1) Is the level of data I have (see screenshot of DSS) typical for this amount of subs? (I have spread the channels out so you can see the data for each. I've aligned each before processing. 2) Should I have used a higher ISO say 1600? 3) Would changing DSS settings make any difference. I use standard mode, Average for Lights & Darks, median for Bias. 4) Is the fact that I'm in a high LP area significantly affecting the quality of the images. There are some fantastic DSLR images of the Rosette nebula on this forum, so I think I should probably be getting better results. I am relatively new to AP so apologies in advance for all the questions. Thanks Dec. -
Yesterday after salsa dancing lessons, I noticed some very clear patches in an otherwise mediocre sky filled with thin wispy clouds, I hooked out the Helios 15x70s and had a quick look at the Rosette. Lo and behold, a faint milky patch showed around the central cluster (should be better from a darker site). I also checked up on Ceres and Vesta, and they had moved quite a bit since last Saturday. They were only visible through a thick haze, near Zenith. After a quick look at M35 I packed the bins up. All (more-or-less) old friends, but I was happy with the quick session -
Hi all, here's the first light from my new modded 1100D: Rosette Nebula by glowingturnip, on Flickr 21x 300s lights at ISO1600, darks, flats and bias, equipment as per sig, Pixinsight processing To say that I'm pleased with this camera would be a total understatement - it's soooo so much better than my old Nikon D80. No amp glow and much less noise and a wonderfully clean master dark, so much easier to process ! And that's before all that lovely Ha goodness too. APT worked very well with it, respect to Ivo, and license duly paid for As for the typo - this wasn't actually supposed to be the Rosette Nebula at all - I was going for the cone nebula and xmas tree cluster, NGC 2264, but made a note of it wrong as NGC 2246 which is part of the Rosette - it wasn't until the day after when I was checking the lights that I realised something was strange, I recognise that cluster... Slightly annoying, I've already done the Rosette once, and my wife even framed it for me for my birthday, and of course now this is my better version, ho hum. I'm slightly concerned though that I have some coma showing, as you can see from the unprocessed corners below, and that the coma seems to be asymetrical. I'm using a Baader MkIII CC, and the scope was laser-collimated at the start of the session. Would appreciate any input from you knowledgeable folks on this. The target was off to the right of the frame so the stars are unfortunately not as round as I'd like, and I had to do a bit of minor offset surgery in the very top-right corner. Anyway, hope you enjoy, Cheers, -
7th November 2015 Equipment: Olympus 10x50mm DPS-I on tripod (6 degree FOV) Time: 02:40-04:00 Orion's Sword: Orion Nebula was glowing quite brightly. There was hints of nebulosity around the Running Man and the stars very crisp points of light. Rosette central cluster was obvious, I thought I saw a very faint haze around it, but it was so dim that it was most likely wishful thinking. Pleiades very crisp and looked great. Through the crispness there was a very slight shimmer/twinkle to the stars. It was a great view, something that definitely needs the stability of a tripod to see. Jewel Box cluster was quite small but about 6 individual stars and a V shape was clearly visible. Alpha Cruxis was visible as double star. The bright primary was not resolvable as two. Cluster at the other side of Crux from the Jewel Box, easterly from the Carina Nebula there was a dense star field, definitely worth putting a camera on it to see if there is any nebulosity there. There was a distinct orange star among the star field, much brighter and orange than any of the other stars around. Initially I thought it looked out of place and reminded me of the supernova spotted in Sagittarius through the binoculars on 20 March 2015 @ 3:42am AEDT (16:42UT). The dense star field was approximately 1 degree in size so will most likely need to be imaged at 500mm f6.25 to get whole object into frame. Carina Nebula was nicely visible, the dark V shape dust lane... or A as it was orientated tonight, was clearly visible among shimmering stars and nebulous haze. As a note there was a star cluster in or near Canis Major to look into. The Olympus DPS-I 10x50mm binoculars are great, clear and sharp for astronomical observing, there is slight distortion to the extreme edges of the FOV but nothing that bothered me at all. It was a great night of binocular observing. MG- 9 replies
