      One Entry Per Member


To increase participation over such a diverse group, the winner will be selected by random drawing. Please feel free to start a thread requesting guidance on your entry prior to submitting it, the whole purpose of this challenge is to learn and compare on a common target. Entries must be submitted by midnight eastern time on September 30, and I will try to announce the winner early in October.


Note: If I am late announcing, gently nudge one of the moderators in a private note, it helps. Seriously, PM one of us!

I spent most of last month trying to get an image for the August Challenge, and finally got a halfway decent image the day after the winner was announced lol!


SO...  I am prematurely tossing this one in the ring.  It is my third ever image.  I shot it a couple nights ago, and it was my first successful night with 10 minute subs.  My auto focuser is "gone" as I await my new Starlight assy, so I had to try and hit focus and leave it there for the night.


It would appear my setup is not wide enough for this subject. I think I will try my first mosaic to see if I can pull it off.


Processing:  I did my first PI integration.  I found a tutorial (in German) that got me through integrating the RGB and then the narrowband.  I KNOW my colors are off, the background is crap (too dark) and it seems that my flats and darks were ignored as I have both vignetting and amp glow in the result.


I am going to post this in one of the regular forums to see if I can learn the proper way to post process this image.  In the meantime, here it is!

Magnificent image! 

May I suggest a small trick. 
- Invert the image
-Use SCNR to remove all green
-Invert back to normal
-Observe the difference

Here is my rendition of the Heart nebula (IC1805), widefield with Fishhead nebula (IC 1795) in natural colors: 


11-16 Heart 140Min csc STCr1J LsSat CN.jpg


It was captured on November 16, 2018 with my gear listed below: 


Location : My backyard in S. Texas,

OTA : Skywatcher Pro80 ED doublet with an Orion 0.8x focal reducer, 

Imaging camera : HA modded Nikon D5300 -

Narrowband filter : Omega Optical's duoband filter which has a 12nm bandpass for HA & 30nm bandpass for H-beta & OIII,

Mount : iOptron iEQ 30Pro,

Guiding : None

Capture details: ISO 800, f6, 140 minutes of total integration time (18x2Min, 21x2.5Min and 17x3minutes). 


The image was processed using APP (Astro Pixel Processor) and StarTools with normal RGB processing workflow. That gives me the natural color palette. The red is dominant because of strong HA emissions, which has been slightly toned down in saturation to help the central star cluster Melotte 15 to show. So, the image lacks the "pop" that a false color Hubble palette might give. Nevertheless, I was happy to get good results. Hope you guys enjoy it too ..... Anil

The SHO images are great, but we need more red in this thread.  Here is a kind of, sort of, HOO image.  Lum(H76x4'+O20x4'), R(H86x4'), G(H20x4'+O20x4'), B(O20x4').  A total integration of just over 6 hours taken on 9/8/2019 and 9/10/2019.  Gain at 210 on the ASI183MM-Pro with Baader NB filters.  Used a Stellarvue 70mm  telescope  at f/4.8 on a CEM60  mount, guided.  Stacked in DSS.  Developed in Star Tools and Gimp.

I decided to try the Hubble palette this time around.  I still have a long way to go in planning and technique, and building a mosaic is a bit beyond me at this point so my image is limited in extent and the camera rotation probably could have been better.  The images where taken from my backyard on August 31st, September 1-4, and 7-9.  I used Astronomik 6 nm HA, SII, and OIII filters to produce 360 images,120 images per filter, 90 seconds per exposure, 9 hours total exposure time. Equipment: ASI1600MM Pro; modified GSO 10" f4 Newtonian; G11T mount, 70mm Astromania Guidescope with ASI290MM.  Captured using SGP/PHD2, processed in PixInsight, conversion to jpg using Photoshop.

For a change, here's my entry.  I had first intended a mosaic, but with my gear that would have had to be at least a 3x2, in RGB 18 different frames (and at least 100 subs for each...).  Might still do that, but not before end September :o


So instead now a session with an old Canon FD 135/2.8 lens and my ASI1600+EFWmini.  That nicely covers both IC 1805 and Sh2 199.  I stopped the lens down to F/3.85.

120 45s frames for each color, taken unguided with random 10" dithers every 3 frames.

Had some issues with the color - not sure if that is the lens or the new filters.  Guess one should always only change one thing at a time.... crazy.gif

The Heart Nebula in “bicolour” with IDAS NB1 filter.


This was taken over two nights for a total of 3h 8m. I used an IDAS NB1 filter which has two bands centred around the Ha and OIII signals. The Ha band is 20nm wide and the OIII band is 32nm wide, so not really a narrowband bicolour image.


The stars were controlled using Starnet++  and combining the starless image with the original image.


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 arc sec total RMS
No Moon, SQM-LU reading 19.9
Location: Rear deck.
Exposures, all at gain 200 and -15C:
Lights: 94 x 120s; Darks: 40 x 120s; Flats: 7s with LED light pad; Dark flats: 7s.
Integration 3h 8m.

Processing software: DSS, APP, GIMP 2.10, Starnet++ and RawTherapee

This is a challenge and a half to process due to the star field. I need an l-enhance to give it a good go.

45x 180s ISO 1600, 10 flats, 20 darks, 60 bias, Pentax K5 astro mod, WO Redcat, iOptron CEM25P, MGEN II, stacked in Sequator (DSS completely fails to do heavy star field ones) and processed in Photoshop.

Hi folks,


Ok, so this target isn't exactly ideal for my imaging train, nor local weather alignment with the Moon's cycle.  But, here's what I got.


This is focused on Melotte 15, the central open cluster within the Heart Nebula, cropped only to get rid of stacking and alignment artifacts.  First Moonless opportunity to image was during a Star Party on 9/21 under clear Bortle 4 skies.  As the crowd started to thin, I fired up the autoguider, threw on the camera and grabbed about 26 minutes of 20 second subs before having to pack up.  No time for darks, and with the disassembly required for travel, couldn't get flats the next day either.  Stacked what I had in Sequator, using darks from last month.  Not bad - actually saw some of the nebula's glow - but it of course needed more time.  Then the weather turned.


Three days later was a short window in the cloud cover, so I grabbed another hundred subs and a set of darks from home (Bortle 5/6), and flats the next day.  The auto guiding system failed (tentatively traced to a bad USB cable connection), so I just ran unguided and without a plate-solved alignment (plate solving uses the guide camera).  Manually weeded out the worst of the result and stacked the rest (24 minutes worth) in DSS.  Looked similar to the earlier session, though with more walking noise (typical with DSS over Sequator).  I expect this isn't the best idea, but I then took the two stacks and mushed them together in Sequator because it's really quick and both stacks were of similar integration time.  Processed the result in StarTools.






Scope:  Celestron 8 inch f/5.6 Newtonian with Paracorr coma corrector

Mount:  Celestron AVX

Guiding (1st night only):  80mm f/7.5 guide scope, ASI174 camera, PHD2 software

Camera:  Nikon D3200, unmodified.  ISO 12,800

Lights:  152 total, 20 seconds each (50 minutes integration)

Calibration (2nd night only):  20 darks, 20 flats, 20 dark-flats

Stacking:  Sequator 1st night, DSS 2nd night, merged with Sequator

Processing:  StarTools

I'm south of the equator, so this one is very low on my horizon. Atmospheric crud and LP made this a tough target. I'm glad I managed to get something.
