Hello all, This is my latest image of the Eagle nebula (M16/NGC6611) in the constellation Serpens, this time imaged through narrowband filters using my 8" Celectron SCT, at F10 - 2032mm focal length, with my astromodded and active cooled Canon 40D DSLR. The second image is a cropped and rotated version to emphasize the famous "Pillars of Creation" part of the nebula, made popular by the HST image of the same name. The color channels are SII, HAlpha and OIII as RGB, and color balanced to remove the heavy green color cast created by the strong Hydrogen Alpha signal. The total exposure time spent on this image was 20 hours and 57 minutes consisting of the following subs exposures: RGB: 13x15s, 19x30s, 17x60s, 12x90s, 17x120s, 15x180s HII: 2x600s, 9x900s, 4x1200s OIII: 1x600s, 8x900s, 1x1200s, 11x1500s SII: 2x500s, 14x1800s All at ISO1600. Clear Skies, MG

Hello All, Sharing with you my natural color image of the Eagle nebula. This project is a WIP as I'm working on exposing narrowband to emulate the Hubble image of the Pillars of creation, but I assembled the 2 hours of 15, 30, 60, 120 and 180 second subs which I exposed through the UV/IR filter for the natural color stars to use in the narrowband image. This has been exposed through a Celestron 8" SCT at F10 with my modded and cooled Canon 40D, tracked on a CGEM and guided with PHD2. The Hardware control and subs aquisition was carried out by APT 3.63. CS MG

Friends, here is the Eagle Nebula (some creationist at NASA has another name for parts of it), which I have processed from data I downloaded from the Liverpool Telescope site. This one is not possible to image from my latitude so I have worked on this data with good conscience. It is from their 2 meter scope on La Palma, Canary Islands. They had quite a lot of data on the Eagle, so I ended up making a four panel mosaic, downloading totally 96 subs from the following filters for each panel: Ha (3 x 60s), Bessell B (mainly blue, 3 x 90s), Bessell V (mainly green, 3 x 60s), Sloan-r (red, 3 x 60s), and clear (12 x 60-90s). Totally 27 min per panel and 1.8 hours for the whole image. That does not sound much so clearly, aperture has helped with the quality of the data. Each sub had to be downloaded separately and processing was at times extremely tedious, initially involving a lot of aligning and trying to rescue the larger stars that were affected by some odd optical artifacts (I attach a panel to show what I was up against). Does anyone know what kind of optical problem that could be? A bit odd for what must be a million+ pound scope but then it is for research and not for pretty imaging. Indeed, I even found eggy stars on some panels.... This is the 39th saved version of the final mosaic and I need a break from starring at it. The data on the nebula is great and my main problems have been with the stars. Any comment sand suggestions most welcome.

Hello Astronomers, I got the Topaz Labs Detail and DeNoise PS plugins and I have to say that they are great... noise is literally seek and destroyed without effecting the detail.... After playing with it for a couple of days I say that the plugins are definitely definitely worth getting. I reprocessed my M16 data from July this year and used topaz detail and denoise to try to get some more detail... I also applied the denoise filter to a JPEG image of the horsehead nebula from last year and, well I think the results speak for them selves. Clear skies, MG

Managed a bit of further processing on data captured on holiday - this field of view is something I would really struggle with at home (it's 9 degrees lower, and doesn't rise above my roof from my garden!) - a widefield of the Eagle (M16), Swan/Omega (M17) and M18, as well as a lot of HII in the surrounding areas. The HA filter helped a lot in cutting through the atmosphere - it's not fantastically high from the site we were at, and I still had to have a couple of nights at it dodging the trees. Details: QHY163M + Canon 200mm f2.8L (@f3.85) + Baader 7nm HA filter, mounted on a Losmandy GM8. Exposure 2h50m in 5min subs. Binned a few subs as they were of poor quality. Processing in PI. Thanks for looking At 50% resolution: Partially annotated version (lots of unmarked catalogues not shown, and not sure why Sh2-47 is marked away from the actual object! :

Here it is, my first published image from my new kit (see sig) ! 9x600s Ha, darks flats and bias, equipment as per sig, Pixinsight. A little lacking in data this one - the very cheapest part of my kit failed me - I'd just got a new mains extender thingy, and it turned out that the socket I'd plugged the laptop into wasn't working, so half-way through the session it ran out of batteries and shut down, along with SGPro and PHD. I'd also started a little late to be honest, so it set on me early. I think I might need to wait till next year to add to this one now. Anyway, hope you enjoy ! More to come...

More and more people are getting their data from remote obsies like the DSW, and I will probably soon be one of them. Meanwhile, the sky being as it is, I go for the free data out there. A few hours ago I posted a Bubble Nebula image I processed from the Liverpool Telescope (LT) on the Canary Islands and I am now onto LT data for the Eagle Nebula. It is a quite cumbersome process of finding and downloading the subs, aligning them and cleaning them up (this is a dirty chip and even if it is an extremely expensive 2 meter scope it adds some odd artifacts to the brighter stars). So I post what I got for Ha so far, both as a B/W image and then I got to into my mind to play with the colours a bit (after all Ha is red so why not make it red). I am now waiting for the energy to find, download and process subs for R, G and B, but it will be coming soon. This is four panels of 3 x 60 secs each so not much data but aperture helps. Comments most appreciated!

On 7th August 2015 I setup the scope and started imaging the Cat's Paw nebula, when I checked on the system 30 minutes later I was DISSAPONTED to find that clouds rolled in... I waited for the clouds to clear but no luck... While I was waiting for the clouds to clear before packing up I decided to reprocess my M16 data that I captured across 7 nights in June and July. Here are the reprocessed images... I'm quite happy with these seeing that the data was captured through Baader Ha, SII and OIII filters on a full spectrum modded uncooled Canon 40D, nights are quite cool tho, about the 6 degree C mark so I guess that helped. I concentrated on lowering the amount of purple halos around stars and attempted to preserve maximum detail, the purple halos are still there but not as severe as in the first version. I still have a bit of noise/grain in these images, but when I ran the noise reduction filter I started to lose detail, and the level adjustment that the detail wasn't effected too much the amount of noise reduction was not worth changing. I think this was the best balance between noise and detail.© Mariusz Goralski

This came as a bonus target, I didn't really plan to shoot it, but I took the opportunity to grab some frames before astrodark or with the DSLR or waiting for other targets So this is a mix of everything: 10x2min Ha with the ASI1600 and 130PDS on the AZ-EQ5. 11x3min Ha with the ASI1600 and Esprit80 on the AZ-EQ5. 19x5min Ha with the ASI1600 and Esprit80, 11 on the AZ-EQ5, 8 on the EQ6-R. 15x5min Oiii with the ASI1600 and Esprit80 on the AZ-EQ5. 74x90s with the DSLR and 130PDS on the AZ-EQ5. For a total of 5:34h. Crop of RGB, HOO and HOO-RGB. Which are your thoughts before I call it the final version? Clear skies! Alex Edit, final:

Here's my last one from my summer crop - it actually turned into a year-long project, I took the Ha in August 2017, the OIII in July this year and the SII in August. 10 each x900s Ha, OIII and SII, darks flats and bias, equipment as per sig, taken in southern Spain, PI processing. Just for fun, here's a side-by-side comparison of my Pillars of Creation vs Nasa's, can you guess which is which ? Ok, not much of a contest really, but then their telescope is a bit more expensive than mine is ! Quite interesting to have a close look though, there are a number of features in common that I have managed to pick up that aren't apparent at first glance. I'd be happy to receive feedback on what you think, feel free to be honest since I'm not quite sure how I feel about it, especially the colours. Comments and cc welcome. Hope you enjoy, Stuart [edited to fix Flickr link}

Hi everyone, As I setup and started imaging the Cat's Paw nebula, when I checked on the system 30 minutes later I was DISSAPONTED to find that clouds rolled in... I waited for the clouds to clear but no luck... While I was waiting for the clouds to clear before packing up I decided to reprocess my M16 data that I captured across 7 nights in June and July. Here are the reprocessed images... I'm quite happy with these seeing that the data was captured through Baader Ha, SII and OIII filters on a full spectrum modded uncooled Canon 40D, nights are quite cool tho, about the 6 degree C mark so I guess that helped.

I think this was the best balance between noise and detail. I have AstraImage and it's great, but I heard that Topaz Labs Denoise is a good noise removal algorithm... Has any one used it, if so how does it compare to the likes of MoiseWare Pro, Astra Image and photoshop? Clear skies...

Hi All, Just sharing my latest image... this time it is the M16... I imaged this at F10 on my 8" SCT hoping that with the higher magnification I would get more detail in the pillars of creation... it's better then the one I've taken about 2 years ago using a f6.3 FR but it didn't come out as well as I hoped it would, the OIII and the SII data seemed to be very dim, so I had to push it more to bring out some nebulosity in that spectrum increasing the noise... I'm starting to think I'm reaching the limits of my modded 40D since my deep sky image quality seems to have stagnated... at least in narrow-band imaging. Personally I prefer the look of the natural RGB image, even though the narrow-band data acquisition was much longer. Image tech specs.... H-alpha: ISO400 7 x 1800s Subs 7 x 900s Subs SII: ISO800 12 x 1800s subs 4 x 2700s subs 5 x 2160s subs OIII: ISO640 4 x 1800s subs 6 x 2100s subs 5 x 1500s subs RGB: ISO400 9 x 630s subs 7 x 350s subs 10 x 150s subs Data captured across 7 nights in June and July 2015. Thanks for looking... Criticism welcome... please be gentle...

In the last few nights I was able to catch more data of M16. I got much better Ha data (better seeing) and also some OIII and SII data, that I had to stretch quite far). In the end I'm happy with the result (it's at only 20 degrees elevation here...). I did some quite extensive processing, also using star masks and the narrowband data to create natural color stars... TEC140 / QSI583ws 6x900s Ha (4,5nm), 4x900s OIII (3nm), 4x900s SII (5nm)
