I made the jump from DSLR (Canon 650D) to a dedicated OSC camera > Zwo Asi294 MC Pro. We've had some good nights with moon not rising till 6am last week. A good opportunity to try out my new purchase! I matched the Asi294 with SW200P telescope on HEQ5 belt driven mount. I used an IDAS LPS-P3 light suppression filter to help in my Bortle 6 class back garden. APT controlled the show with Zwo 120mm mini guide camera keeping total RMS error to less than 0.3. This was one of my longest integration times at 5 hours (60x300secs subs - 1x1 binning) using default unity gain (120) and offset (30). The camera was cooled to -10deg. Calibration frames included Darks, Flats and Dark Flats. Stacked in DSS (RGGB matrix) and processed in Photoshop CS2. I think this is an improvement of my DSLR version - also included below. I hope you agree and am looking forward to imaging a lot more DSO's with this new camera. Zwo Asi294 MC Pro M51 Whirpool Galaxy: Cropped Version: DSLR version:

These nebula (also known as the Christmas Tree Cluster) are about 2600 light years distant in the Monoceros constellation. They are reflective and emission nebulas - the Foxfur nebula is formed by interstellar dust reflecting light from the brightest stars which glows blue. I managed to capture 60mins of RGB data (no filter) and 45mins of 'H-alpha' data (using the L-eNance filter) over two consecutive nights with the moon at first quarter in mediocre weather conditions. Bortle class 6 back garden. Equipment: HEQ5 mount Canon 650D (ISO1600) SW200P Stacked in DSS and processed in Photoshop CS2 (two images into one). Hope u like.

Had a couple of decent evenings lately to have a look at the Orion constellation but not with the telescope. I have wanted to try out my Canon 50mm and Sigma 105mm prime lens on this target for sometime! I set-up the Heq5 and piggybacked the DSLR and above lenses on my refractor and shot off 30 images of Orion with both lenses. I used f2 aperture and ISO's of 800 and 1600 on the Canon and Sigma respectively. Each shot was of 30secs duration. Usual calibrations frames were taken and integrated with the lights in DSS and processed in Photoshop CS2. For such short integration times I was very happy with the result - hope you agree and CC's welcome. Canon 50mm Image: Sigma 105mm Image:

Another brief period of quite clear skies (so rare lately) but under a near half moon last night - beggars can't be choosers!!! A bit windy so guiding was a struggle, hey ho, at least refractor doesn't sail as well as a Newton 200P. Canon 650D SWED80 and 1hr 20mins of useable lights. Darks, bias and flats too. The result: Hope u like CC's welcome

A small break in the relentless clouds allowed a brief opportunity to image this classic in Orion. I aimed for 6 hours but only got 90minutes! Enough for a stack!! Acquired 30 useable lights of 180secs duration with a Canon 650D set at 1600 ISO. The SW ED80 and L-Pro optolong filter helped with the result. CC's welcome.

My best 5 - all shot with my Canon 650D in the first half of the year with SW200P and SW Evostar 80ED.

Thank you Mike. Yes - normal equipment and what it is capable of!!! I found that using starnet to produce a starless image really helped in the processing. I would like a dedicated ‘Astro’ camera but the chronic bad weather puts me off such an investment. Gerr.

Cocoon Nebula (IC 5146) is a reflection/emission nebula located in Cygnus 4000 light years away. It spans 15 light years across and is an interstellar nursery where many new stars are being born. The bright star at the centre of the nebula illuminates the concentrated molecular gases present that allows astrophotographers to capture its structure. This was taken two days ago in my Bortle 6 skies when clouds parted for a couple of hours (they have since unexpectedly and annoyingly returned). Lights: Two hrs worth (4 min subs). Dithered on PHD2. Darks, flats and bias frames also integrated into DSS for image processing - then Photoshopped (CS2). Canon 650D (modded). Optolong L-eNhance filter. SW200P on HEQ5 Mount (Rowan belt) - guided. CC's welcome.

Can you not place an aperture type mask at the front end of the telescope? I'm wondering whether putting something like draft excluder foam around the inside edge of the front of the telescope would have a similar effect to the methods outlined above?? Or is this idea too simplistic / ineffective??

First clear night in like forever! A full moon (18th) put my usual DSO's to bed but I wanted to capture something! Never tried my guide camera at imaging so the ZWO 120mm Mini was aimed at the big white disk and 12 videos were taken in conjunction with my SW200P. The vids were processed and stacked in Avistack. Images were then sharpened in Registax. Hugin was used to stitch the images into a mosaic which was further tweaked in photoshop. I'm quite happy with the result. CC's welcome.

No clear nights whatsoever in North Wales past 6-8 weeks. Any promising windows of clear weather were all too quickly dashed. Fortunately this weather has stopped me from spending ££££'s on new astro gear. Every cloud has a silver lining!!

Hi, this is my first attempt at the heart nebula in Hubble pallete colours. Not had much else to image in past two months so I thought I'd give it a go. Equipment in signature - about 3.4hrs of image acquisition. Hope you like!! And this is the original image: Yeah - I faked the Hubble colours by splitting the channels in the original image and re-constructing a new RGB image. Until I can afford mono and get nice clear skies this will have to do!!!

The Heart Nebula (IC 1805). This lies in the constellation of Cassiopeia about 7500 light years from Earth in one of the spiral arms (Perseus) of our Milky Way galaxy. The atrocious weather in the past 2 months has allowed for two brief imaging sessions allowing for 3.4hrs of total imaging time only! Lights: 51x240secs with flats and bias frames. Imaging Camera: Canon 650D. Processed in DSS and Photoshop CS2. CC's welcome.

My imaging session is usually interrupted and cut short by weather but with OSC I can at least process the captured data to produce an image even if I have only 60minutes acquisition time. Can you say the same with Mono? I'm thinking interrupted filter loops would be more hassle to restart on other nights to reacquire data useable to process an image. With Mono you'd need to acquire data through all the filters to make it a worthwhile pursuit (esp. additional costs associated with mono and auotofocusers). Don't get me wrong - I like the mono images but I think if I went that route then I would want clear uninterrupted imaging sessions for it to work effectively as Mono is more involving where more things can go wrong than with OSC. Just my opinion.

Absolutely agree with above response in cloud, rain and wind predominant skies!!! But if you are lucky enough to have more than one clear night in a row than potential integration times would be more persuasive for Mono imaging.

The weather has stopped me adding data to this galaxy I imaged three days ago so I tried a new astro processing technique in photoshop using Starnet ++ and masks. I'm pretty happy with the result. Hope you like too! Andromeda M31 by Gerr. For comparison the old image:

Andromeda is back! Weather in North Wales has been pretty bad over the last month but last night a window opened to grab this big galaxy. In between cloud dodging under a waning crescent moon I managed to get 99minutes on this target in my Bortle class 6 garden. Image is so so but I'm just happy to be out there again!! HEQ5 Pro Mount. SWED80 Refractor. Optolong L-Pro Filter. Canon 650D (ISO 1600). 33x180secs lights (plus bias and flat frames). DSS and Photoshop CS2. CC's welcome!

Some nice detail but looks like part of the Pacman nebula to me?

I decided to apply the HLVG filter in photoshop to reduce the green envy on this image!!😂 Bit better on the eyes now at least!

Super Image! I've just posted my butchered version of this galaxy taken with a DSLR (Canon 650D). 😂 Wishing I had a dedicated astro cam like yours!! Gerr.

Triangulum Galaxy (M33) is a spiral formed galaxy 2.7 million light years from Earth in the constellation Triangulum. The third largest of the Local Group of galaxies behind Andromeda and our own Milky Way. I found this one very challenging to image (low surface brightness) and to process (despite over 4hrs image acquisition time)! Lights: 62x 240secs at ISO800. Canon650D with Optolong L-Pro filter. SW200P Reflector on HEQ5 Pro mount. Waning crescent moon. Bortle 5/6. Stacked in DSS and processed in Photoshop CS2. CC's please! Gerr.

The Dumbbell Nebula (M27) is a planetary nebula in the constellation Vulpecula. This lies about 1200 light years away and is the second brightest planetary nebula (after Helix nebula) in our night sky. It has formed from the ejection of the outer shell gases of the central star in the image. Taken last night in my Bortle class 5/6 back garden. 64 Lights at 60 secs ISO800. Optolong L-Pro filter. Canon 650D on a SW200P reflector mounted on HEQ5 Pro. CC's welcome. Gerr.

This is the Jpeg image!
