Managed to get another couple of hour of #Ha & #Oiii on my #M27 #DumbbellNebula image now up to 5 hours. Taken with @Celestron #C8sct @AtikCameras #Atikone 6.0 and @baader_astro 7nm filters at 1280mm focal length #Astrophotography #AstroHour #witns #Astronomy
Here is a quick stack and process of #M51 #Whirlpool taken last night. 4.5 hours RGB taken with @zwoasi #asi533mc with an @Optolong_filter #LPro filter using my @Celestron #C8sct with an f6.3 reducer. From my #Bortle8 sky #Astro #Astrophotography #GalaxySeason #AstroHour
Finally managed to get enough data to process my heart of the #HeartNebula image. Just over 13 hours of #Ha #Oiii & #Sii taken with @Celestron #C8sct with @baader_astro filters using @AtikCameras #Atikone #Melotte15 #IC1805 #witns #Astrophotography #Astronomy #Astrohour
This is a second RGB image of the planet Mars as imaged from my back garden on the 23rd September.
However, this time I used a Baader 685nm pass IR filter image as a luminance channel.
The resultant IRRGB image was then labelled to identify some features resolved on the Martian globe using my relatively modest C8SCT ZWO290MM combo.
I then used online "Calsky's" spaceship simulator to produce a simulated view of Mars from space orbit at the time and date that my image was acquired. I am pretty pleased with the comparison!
Three separate IRRGB filter runs. Sharpened in Registax then derotated using Winjupos.
Assembled and finished using Photoshop 2020.
Many thanks for looking and best regards.
A monochrome shot of the giant planet Jupiter with icy Galilean moon Europa for company. Europa would eventually pass behind Jupiter later in the evening.
Imaged with a Celestron C8SCT and a ZWO290MM camera.
This RGB image represents the result of a total of 3 mins each of Red, Blue & Green Filter runs. The images were then derotated using Winjupos to negate the smearing effect of Jupiter's rapid rotation over this period.
Jupiter's altitude was a paltry 14° when imaged using a Celestron C8SCT and an ASI290MM camera equipped with Baader filters.
An image of Jupiter with one of its Galilean satellites, Europa.
A little later in the imaging session and Jupiter was joined by Europa in the frame. Europa was on its way to occultation by Jupiter and not to transit unfortunately!
Jupiter had now increased its altitude to 20 degrees from my site but unfortunately seeing was deteriorating despite this!
The Great Red Spot is nearing the end of its transit.
Imaged with a Celestron C8SCT and a ZWO290MM with TAL x2 barlow and Baader RGB Filters.
A #Galaxy for #FirstContactDay
I have processed my #M106 data from Saturday night, added it to my data from March.
7.5hours RGB taken with @zwoasi #asi533mc through my @Celestron #C8SCT with f6.3 reducer. #Astrophotography #WITNS #Astronomy #Space
An image of Tycho captured on the evening of 02.12.14. A relatively young crater Tycho is sharply defined and is the centre of a prominent ray system which becomes evident near and at full moon.Notable in the image is the lower albedo of the surrounding terrain compared to the crater interior. The crater floor is relatively flat, but, as is evident in the image, it also has many small knobbly hills giving a rough appearance! The central peaks rise almost 1mile above the surface.
Imaged with a Celestron C8SCT and an ASI120MM camera.
Had a play with the #Ha @#Oiii data I captured of #M27 #DumbellNebula this week. 20x5min subs Ha & 13x5min subs Oiii. Captured at 1280mm focal length with @Celestron #C8sct with f6.3 focal reducer and @AtikCameras #Atikone 6.0 and @baader_astro 7nm filters #Astrophotography
A second and larger version of Venus imaged by UV filter on 28.01.17. Imaged with a Celestron C8SCT and ASI290MM camera fitted with an Optolong Venus (U) filter. Nice contrast between brighter polar regions and swirling cloud at the equator I think.
Jupiter captured at 21.30UT - 28.02.2016 - Altair GPCAM (Mono) and RGB filters - 1 minute avi captured of each channel, stacked with AutoStakkert selected best 30% of frames. Channels then combined in Photoshop. Bit of enhancement in Photoshop, no wavelets applied. Scope - Celestron C8SCT (2032mm @ ƒ10)
Exposures - R:10x120s, G:10x120s, B:7x240s, Lum:25x30s, Ha:7x300 (totaling 1hr 55min)
Equipment - C8sct on CGEM reduced to f/3.3 thru Astronimik filters on ATIK320e camera
Finally completed my Ha data on this tonight (LRGB was gathered on 6/23, Ha tonight on 6/28) - which really helped the image as a whole. My Red channel was nearly useless thanks to some pretty nasty LP in the area that night (more water vapor or pollution than normal). This also resulted in me having to do shorter exposures than M101 is deserving of, but I was able to lightly capture the faint larger "elbow/forearm" section (upper left) and the twisted arm (at the top). I was happy the Ha data highlighted the dust lanes near the core. I have some gradients in the background, but still, this is a big improvement from last years efforts, so I'm happy to be improving a small step at a time.
Jupiter imaged using a Celestron C8SCT x2 barlow, captured with Altair mono cmos GPCAM and Altair LRGB filter set. 500 frame stack for each channel. Stacked with Autostakkert AS2!, sharpened in Registax 6 and channels combined and processed in Photoshop CC.

I just did some extensive testing with IC Capture and a DFK21au04 (color) and for me on Jupiter, brightness wasn't the issue - the deciding factor was having Gamma at or above 120 resulted in onion ringing. Below is my last round of data. G=Gain (0-1024), Exp=frame exposure (seconds), Gamma (0-255), Brightness (0-63). For reference, on my system C8sct with 2.5x barlow, Exp of 1/30s and Gain of around 500 makes jupiter almost completely invisible (dark) so my tests of G=650 made for a pretty underexposed image.

Another classic target that I've somehow overlooked until now - The Crescent Nebula. Wikipedia: The Crescent Nebula (NGC 6888 or Caldwell 27) is an emission nebula in the Cygnus constellation, about 5000 light years away. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray emitting temperatures.
This is 90min of data consisting of: 15x300s Ha->Red, 15x30s Green, 15x30s Blue using a C8sct on a CGEM mount at f/3.3 on an ATIK 320e
still having some star issues in the corners, but nebula shows decent detail. 10min subs would show more in the central area.
