Red, convoluted clouds of glowing hydrogen gas 1,500 light years away are energized by the hot type-O star AE Aurigae in the  Flaming Star Nebula (Right).

Far more distant at 12,000 light years, stellar winds from a young star cluster sculpt the glowing gas of the Tadpole Nebula (Left).



Rasa 8", asi071mc-pro, EQ6-R Pro, Radian Triad Quad-band filter. 
Captured with N.I.N.A. and processed in PixInsight.
Processing: DynamicBackgroundExtraction, BackgroundNeutralization, HistogramTransformation, SCNR to remove green, CurvesTransformation for brightness and saturation, DarkStructureEnhance, MorphologicalTransformation on StarMask.

The data for this picture was taken on Oct. 7, 2019 with the 8" power-newton at f/2.8 and the ASI183mm-pro(160 gain at -15C) and Baader NB filters.  38x4' H-alpha, used as luminance  and red,  19x4' OIII used as green and blue.  The mount was a guided CEM60.  The data was stacked in DSS and developed in Star Tools and Gimp.   This telescope gives a lot  of detail, but the stars along the edges are still showing comma.

The Flaming Star


I was really excited about my narrowband view of the Flaming Star nebula last month, so I devoted one moonless night recently to seeing what it looked like in natural light to see if I could pull out the more subtle blue-purple reflection nebula aspects of it. It worked! After processing in Pixinsight, my narrowband image was processed with Starnet++ to remove stars, and then I added back in the brightest ~50% of the stars from the original image. For the blending in the broadband reflection nebula light and color, I staraligned the two master images in Pixinsight and then combined them in Photoshop, blending the broadband blue colors into the narrowband image through the use of a layer.


What do you think? You can find all of my new work on Instagram @gazingoutwards. I hope you enjoy it!


Gear and shot details:


Borg 107mm refractor at 420mm focal length and f/3.9. Hobym Crux 170 mount with QHY367C camera, with Triad Ultra narrowband filter and Optolong L-Pro light pollution filter. Off-axis-guiding with ASI290mm-mini guide camera.


Broadband image 17x600 sec subs. Narrowband image 20x1200 sec subs. All calibrated with flats, darks, and bias frames using Pixinsight and Photoshop.

Here is my rendition of the Flaming star nebula (IC 405) in Auriga constellation, It has just under 4 hours of integration time on a night when moon was not interfering. It was cold for S. Texas (38 degrees) and a bit breezy with wind gusts to 15 mph : 


12-17 FlamingStar 229Min HaO3Color csc STCrLMJ-CN.jpg


Capture details : Captured on December 17, 2019 from my S.Texas backyard

OTA : Stellarvue Access 80 ED with an Orion 0.8x focal reducer, 

Mount used : iOptron iEQ 30Pro - polar aligned using PoleMaster,

Filters : Omega Optical's duel narrow band NPB filter with a 12nm bandpass around Ha and another 30nm bandpass around Hb and OIII lines, 

Guiding : None.

Imaging camera : Ha modded Nikon D5300,

ISO 800, f5.6 and 229 minutes of total integration time  (26x4minutes, 21x3Min, 24x2.5Min and 1x2Min) using the NPB filter. No other filters were used. 


Early in the imaging session, I thought I lost the night because of technical issues. My camera suddenly stopped recording - I thought it was busted. However, after losing about 45 minutes to recovery efforts, I realized it was the SD card in the camera which had gone caput. So, changed the SD card and it was all well. So I lost about an hour in the whole process, but still managed to get almost 4 hours of integration.


I like the final result. Hope you do too! ..... Anil

Images acquired with Celestron C11 EdgeHD / Hyperstar v3, Optolong L-enhance filter, ZWO ASI1600MC riding on an AP Mach1GTO. 43x300sec exposures with an external guidescope.

The Oiii/Hb band of the L-enhance is quite broad so star sizes are more along the lines of LRGB stars rather than nice tight narrowband stars, which I found quite challenging in this very star rich field, so I elected for a star removal technique.


Usual pre-processing in PixInsight with DrizzleIntegration.


Initial autostrech and StarNet, subtraction of starless result from original to extract stars. Extract Lum and binarize to generate detailed starmask.


Fabian Neyer star removal:

Generate multiscale starmasks with MT/Closing applied to starmask; I used scales of 25, 15, 9, and 5. Subtract larger scales to isolate specific scales

Apply masks to original LINEAR image, remove stars with MMT

Subtract new starless from original to generate background corrected stars

Reduce star glows by subtracting progressively convoluted bc stars from starless.

Fill star holes with multiscale masking and MMT


Match background noise in filled areas with NoiseGeneration

Histogram and CurveTransformations

Residual halos around large stars patched with CloneStamp



Blotchiness reduction with MMT at pertinent scales

Contrast enhancement with LocalHistogramEqualization and MMT


Stars were processed by star reduction with MT/Selection for size reduction, less aggressive HistogramTransformation, and masked CurvesTransformation to reduce halos


Stars added back with PixelMath.

50% reduction and JPGification for upload here.


I'm still not 100% happy with the result; maybe 80% LOL although I am happy to be able to reduce stars and sharpen without dark halos around them.  I find the star removal challenging and even though the starless looks fantastic in isolation, once the stars are added back somehow more subtle aberrations become more visible. So still experimenting and refining - possibly using the starless result of this process with Adam Block's halo mask technique might produce a better result if the intent is to retain some stars.

Thanks for looking!

Here is my entry for IC405


So far this December, we’ve only had 3 partially clear nights, so I’ve only been able to collect ~3 1/2h  of data for IC405. Even then, the seeing and sky darkness were worse than normal.


DSS was used for stacking, APP for light pollution removal and colour correction and noise reduced with Photoshop Elements Dfine2 filter. Stars were then removed with Starnet++ , the starless image further processed with GIMP and combined with the original image with stars. In order to bring out the reflection nebula, the blue and green channels were copied and added as a separate layer. 

Scope: ES ED102-FCD100 at f7 (714mm) with Starfield  field flattener
Camera: ASI294MC-Pro
Mount: CEM60
Guide scope: Starfield 60mm with ASI120mm-S and ASI290mini
Filter: IDAS NB1 nebula contrast enhancer.


Guiding error 0.7 to 1.0 arc sec total RMS
SQM-LU reading 18.7 to 19.0
Location: Rear deck.


Exposures, all at gain 200 and -20C:
Lights: 109 x 120s; Darks: 40 x 120s; Flats: 40 x 5s with LED light pad; Dark flats: 40 x 5s.
Integration 3h 24m.

Hi All;

This is my 1st effort with the SVX152T (1200mm F/8) and QHY 367C (no filter), on MX+ mount. OAG guiding with Ultrastar

December 15,18,19 taken before moonrise, Sky quality 19.74

Integration Time: 12.75 hours (51 x 900 sec)

Image scale: 0.84''/pixel

Crop: about 2/3

Processed during a PI tutorial given by Ron Brecher. My flat frames did not work so well and bias were not available (operator error)

I like the blue regions which were the result of not using a filter (triad).

Taken last night. I am very new to narrowband, this object seemed to not have any OIII, which makes the sho palette looks rather "boring". Not knowing what I was doing I blended and messed around with the colors in APP and RawTherapee until I got something which seemed at least interesting to me smile.gif





A less "artistic" more traditional SHO attempt

Yes, i made it just in time!  Sold off my mount and had to wait a while for a new one to get here.

It rained an inch, and the sky said clear for about an hour.  Time to test new mount and nab a quick image!

I experimented with different filters on this subject and ended up with less integration time as a result, but I'm still learning.  My OIII exposures didn't turn out very well so I assigned Red=HA, Green=SII, and Blue=SII.  Processed in PI, non-linear processing using MaskedStretch, HistogramTransformation, and MultiscaleMedianTransform.  Equipment: ASI1600MM Pro, WO GT81, G11T, Astronomik 6nm HA and SII filters.  Total integration time 3.4 hours (HA 34x3'; SII 34x3'), images taken this month on the 19th, 21st, and 26th.
