Been great to have a few nights of clear sky - I captured this last Wednesday/Thursday last week. I have only Just getting to grips with narrow band imaging/processing and I am sticking with tried and tested SHO Hubble palette for now, but very interested in the percentage combinations like the wide field recently posted by @Adreneline - Cave, Bubble and M52 - to name but a few. I'm assuming the colour palette combinations are implemented using PixelMath functions in PI - I will do some reading and jump into the processing threads to find out more I think. But for now here's my latest SHO na

I have been doing this for many years using a star adventurer with a canon 6d and different lenses upto 200mm from dark sky locations. I wanted to get proper scope and EQ mount for a while but I didn’t think it was worth it shooting from the cloudy UK and I didn’t realise bortle 5 skies were good enough for it. After realising I was wrong I bought a HEQ5 and WO zs61. (I wanted a relatively small scope to begin with). next thing I want to get is a dedicated astro camera. And of course going mono makes the most sense. Coming from a landscape photography world, bigger sensor is a

I've been less active lately in this hobby, but I've a few images done, others waiting in the pipeline to be processed. This is a "crowded" area of our Milky Way galaxy, visible all summer from the northern hemisphere. The Cygnus constellation is home of many named and nameless nebulae. Starting from the left (North), below the brightest star, Deneb, the Pelican and the North America Nebulae are very popular; going to right, just below the brightest star close to the center of the image, Sadr, lies the Gamma Cygni Nebula. A bit towards the top-right there's the Crescent Nebula and going

Hi everyone, I've been beavering away on a couple of images, one of the Pacman nebula and this, my first Horsehead. Shot over several nights in my back garden. Terrible weather meant a big gap between imaging nights - it's amazing how you (or is it just me?!) forget the little details in just 8 or 9 days... Lum data is lacking a bit and I couldn't tame mighty Alnitak. But I like the result. Anyway, a number of firsts here - first completed image with the Lakeside focuser, first true tests of APT's recently added auto meridian flip (works great!) and first time using Astro P

Season greetings! Got my 80 Esprit around one week ago and yesterday was the first clear-ish night since. I came to my parents' for Christmas and here the skies are much better. I went to a hill nearby where our galaxy was visible. I had an EQ5 which I didn't polar align very well. I tried to start my RPi3, but it didn't connect to my mobile router so I had to forget about it. I was limited to 15s or 20s subs. The scope is quite heavy, heavier than I expected, it doesn't balance well with a Canon 550D attached. I had to tighten its dovetail towards its end as much as I could and the setup

Happy to see the stars again last night, though cirrus clouds were everywhere. With some luck I got some (short) time with lower cloud density and I pointed the scope towards the Orion. 32x30s usable longest subs, 15x10s for the core and I also used 14x20s taken on the 25th to remove the big halos caused by the brighter stars seen through clouds. I could not expose longer, I only had my DSLR and my EQ5 mount, no intervalometer. The second picture contains some narrowband data I had, which I added in a very small amount to the RGB image. Ha as red and O3 as G and B. This is taken through a

Hey fellas I have a 1600mm cooled version. I was spending Last couple of nights in field trying to do some AP, but the camera didn't work. Everything seems to be ok. I have temperature's info, the 120mm data comes in flawlessly, EFW works just fine. But when camera finishes the exposure it hangs on downloading. I reduced usb traffic, no luck. I switched programs, sharpcap, SGP, nebulosity and even maxim-dl. I switched cables, and again no luck. I took my rig home, set up evertything and camera works just fine. Everything is ok. I took 40, 4 min frames, not a single problem. Then I too

Funny thing - I have an ASI1600 + EFW and am connecting to SW coma corrector which requires 55mm spacing. The camera is 6.5mm the EFW is 20mm, total 26.5, so 28.5mm spacer required - sound correct hopefully? But the suppllied spacers are 21mm and 16.5mm which doesnt help (and doesnt seem correct even for a colour ASI1600 with no EFW) There is also a 11mm female/female adapter and a very short 1.5mm male/male adapter, so I guess I could use the 11mm F/F followed by the 1.5mm M/M + the 16.5 giving 29mm but this seems a bit complicated! Just wondering what other folk do - I cant be the -

Imaging with a 106mm telescope with pulse guiding I have been posting a few images since I started using the ASI1600MM Cool about a year ago, but they all used my 135mm Samyang lens. In the new year we had a few clear nights and although I wanted to carry on with the mosaic of Barnards loop in Ha7nm, the trees in the hedgerow behind my house became part of the frame – not a good thing. I looked at Star Gazers Lounge for inspiration and many images in January were being posted of the Rosette Nebula, so I slewed over to that, with the 135mm lens and started imaging. The result was ‘ok’ bu -
Been working on this again, still with old data. Loads of gradients that I can't seem to get rid of. I dumped a lot of [NII] subs that had rubbish stars, elongated and trailed. TS 80mm f/4.4 six-element astrograph, 3nm Astrodons, ASI1600. I think I ran 5 min subs at max DR. Captured in Maxim DL processed in AstroArt5. Sigma Add stack, multiple gradient removals, ans several Histogram Stretch iterations. Need more data. I have 2 hours of decent HII, but I want to add new [NII] and [OIII]. C&C welcome, and suggestions for further work. The JPEG looks nothing like the FIT

Good evening to you all, Last night I acquired 30x180s on each RGB so now I have a total of 37x180s each RGB, 60x60s lum from last year, 55x180s lum from this year and some shorter exposures for the core. That means ~5:33h of RGB and 3:45h of lum. All taken with the ASI1600MMC and the 130PDS newton, horrible gradients when using the light pollution filter. I mean really horrible and uneven gradients. I also have a horizontal line at about 1/4 from the top reflected from somewhere. The image below was stacked and merged with APP, I also made a synthetic lum from the RGB and included

All, last night was cold and clear but the seeing was not as good as last Sunday, a lot more moisture in the air, I headed out at 10:30pm, when the local sports field turns off its floodlights and spent about 2hrs capturing more data. I got Orion Constellation back in view and I used APT Framing tool to help replicate the framing from Sunday's session and shot a set of RGB subs and further L subs, 30s, 15s,10s, 1s and 0.5s to try and get some dynamic range into Orion Nebula. All the subs were taken with ASI1600 set at unity gain and at -20degC and still using my Samyang 135mm set at F2 m

Good day all, During the first half of June I worked on this 4 panel mosaic of the LBN 239, 241, 243 complex in Cygnus. Besides the bright component ic1318a it was a test for my new asi1600 on some fainter nebulae. I think the small cmos camera is holding up pretty good. Very little noise, I did not use any noise reduction in the post processing. The calibrated frames have been stretched and stitched together in PS. Details: Scope: 10" f/3.8 Newtonian CMOS: ASI1600MM-Cool @ -20°C Filter: Astrodon 5nm h-alpha Exposure: 20 hrs total (5 min subexposures binned 1x1); Un -
Everyone, This is only my second real attempt using my ASI1600MC with 5 filters, LRGB and HA (7nm), prior to this Ive been using a un-modded Cannon 600D with my 106mm APO. But this image was taken with a Samyang 135mm lens, many people talk about how good it is at f2 and I am very pleased with how my image has turned out, it is by no means perfect in any sense, there are gradients all over due to light pollution from two distribution warehouse parks, to my north and south west and skyglow from Milton Keynes to my South East. However, this is where I live so I have to work within the li

Hi everyone, This has been on my hard drive for some months, so nice to have finally got round to processing it! Shot over several nights in January in my back garden. NGC 281, also known casually as the Pacman Nebula, is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm. It lies about 9,500 light years from us and is 48 light years across. As the final version, I've gone for a crop, which I think holds up well, though I'll include the wider fov version in the next post. I used a

The Wizard Nebula An emission nebula 7,200 light years away and my first proper project of the new imaging year. Really happy with it as I’ve had a steep learning curve with new kit so really pleased to see this image come together. It’s also the first time I’ve imaged it. 72x180s subs collected over 2 nights 24/25th August in my Bortle 7 back garden, Whitley Bay, England Calibrated with darks, flats and dark flats in DSS and processed in SiriL and Photoshop.

I took my first Ha image last night and tried to combine it with data of the same object taken previously. First, the Ha image (consisting of only 3x5min subs) just looks like a luminance ....but not as good Second, when i combined it with the old data in PI....I really did laugh out loud (or hahaha as noted in the title). Can anyone suggest a tutorial on LRGB/narrow band imaging either here or on the web - I can find them but if someone knows of a good one (and that's what this forum is for right?) then I'd really appreciate it. Thanks David

A few 'firsts' for me here:- First ever RGB image First ever image processed in Pixinsight - all thanks to HarrysAstroShed tutorials First 'proper' use of ASI 1600MM-C with Mini EFW First image through the OpticStar 127mm Apo R,G and B - 30 subs each @8 seconds with ASI1600MM-C set to unit gain, offset 21 and @-20C I have a lot to learn (many more tutorials on Harry's site, the LightVortex site and also Warren Keller's book) - but its a start. Now - How do I get my luminance image (60 subs - other settings as above) incorporated Next time I'll get t

*£1300 including recorded delivery to the UK; or £1250 if you can collect from central Bristol.* Hi all, I’m looking to sell my ZWO ASI1600MM-Cool plus accessories as a bundle. I’ve had a great time with this camera, but now have a baby daughter that is leaving me zero time for astro imaging! So I’m parking the hobby for a few years… but I’ll be back! A lot’s been written about how good this camera is so I won’t reiterate all that, except to say that I’ve had a lot of success coupling it to my ED-80 ‘scope and HEQ5 mount. I image from central Bristol and the light pollution is horren
