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

I set up yesterday despite a bad forecast to try and fix a cabling and power issue, as the night drew in I noticed the clouds starting to clear a little so stayed setup. In total managed about 2 hours of clear imagining - a lot of the subs I took though were pretty dire - I think in reality whilst it looked clear to the eye there was a lot of moisture in the air, and maybe some high cloud too. After calibration I was down to 10 good subs of 180seconds. Decided to quickly process it today to practice, a few tweaks to reduce smaller stars (I prefer the look slightly) other than that I

Wrapping up in double layer goose feathers I braved the obsy last night. I planned a tour of Auriga with a view to chucking in some favourites. I set up the ED150 on the AZ EQ 6 and fitted the WO quartz diagonal accompanied by my ES 20mm 82'. I stuffed my Astronomik 1.25" UHC (bargain price thanks @FLO) in my pocket too. This set up required the retro children's playroom chair with the legs sawn down due to the position of Auriga. I spent about half an hour checking the plethora of open clusters sprinkled in or near the Milky Way. The sky was one of the best this season so it was a jewell

I recently bought an Astrodon 3nm Ha filter for my new mono camera. It was half price so I couldn´t resist and 2 nights ago I got to try it for the first time. Yep, it delivers! The image was a breeze to edit. The only thing I have to fix is a backfocus issue (I think) that gives me elongated stars in the corners. So, this is 44*5 minutes with the ASI 1600MM-Cool and the Astrodon 3nm hooked up to a Samyang 135mm lens @f/2.8. My guider malfunctioned so I thank the short focal length for allowing me to shoot 5 minute subs Can´t wait to catch some OIII to make a bicolour version! O- 12 replies

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 )

90min HII, 72min [NII], and 80min [OIII] in 2 min subs with the 80mm f/4.4 and ASI1600 MMC camera through 3nm Astrodons. Piggy backed on the 130 f/7 mounted on the DDM60 and encoder guided. Sigma Add stacking in AA5, then gradient removal, alignment and Trichromy with [NII] mapped to Red, HII to Green, and [OIII] to Blue, following the Hubble Palette. Multiple Histogram Stretches, and a Low Pass filter to get rid of some of the noise. The RGB stack needed a serious crop as the [OIII] subs were at a steep angle to the other data, which is a pity as I can see plenty of outlying detail

During recent night I've managed to take only 50 minutes of OIII in narrowband so I could add to previously gathered Hydrogen. This is more like experiment as it is my first bicolor image. Scope: Skywatcher Evostar 80ED DS-Pro with flattener Mount: NEQ6-Pro Camera: QHY168C Filter Baader 7nm H-alpha , Baader O-III CCD Guiding camera: ZWO ASI120MC Guiding scope: finderscope 16x300s exposure at -10°C (80 min total) in H-Alpha 10x300s exposure at -10°C (50 min total) in OIII

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 t

Had my longest session ever, 6hours, last night/this morning. Started off last night on the Flaming Star then had a go at Orion's Head and finally a few subs on the Rosette. Flaming Star. 18x600secs Atik 383L, Samyang 135mm f2 Astrodon 5nm Ha filter. Next, went over to Orion's Head, all of it still does'nt fit on 135mm. 12x600secs Atik 383L, Samyang 135mm f2 Astrodon 5nm Ha filter and finally The Rosette 8x600secs Atik 383L, Samyang 135mm f2 Astrodon 5nm Ha filter

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.

Hi! I would just like to ask if it is possible to get a decent image of the Rosette Nebula using an unmodded DSLR. I'm planning to take a series of around 120~150 secs shots. Thanks!

My first attempt at processing the subs I took last night. Not totally happy yet - next time I process it I think I need to boost the red in the mid tones somewhat to try to compensate for the filter in my standard Nikon D5300.
