Deep Sky Astrophotography

[StudentOfLight]

The Prancing Horse nebula, Rho Ophi Molecular Cloud Complex, and Great Bulge.
Total Exposure: 22x 8.0s @ f/1.4, ISO 1600

I'm loving the new 35L lens if Canon releases a similar 135L update I'll be over the moon.

DSS has been driving me mad. It failed 7 times trying to stack approx 240 light images, every time with a different issue. With great frustration I just ended up stacking 22 tif files with with a manual vignette guestimate, so no proper calibration. I'll try and find out what is going wrong when I've gotten some sleep and have a fresh mind.

Anyway, there is such a wealth of deep sky objects in this region of the Milky way. I hope the next month or so I'll have clear skies again and get a chance to zoom in and get some good quality exposures with more pixels on target.

I love the results you're getting... your processing is improving nicely.

Nice work! That's a great FoV.

DSS does have a good number of bugs, and it crashed frequently with me as well. That was one of my primary motivations for moving to PixInsight, which allows me to successfully integrate thousands of frames if I need to. It is not free, but it is WELL worth the cost, IMO.

Quick note. The green cast in your image? You can eliminate that with HLVG, or Hasta La Vista Green, a plugin for Photoshop. Or, you can use the SCNR tool in PixInsight. Either will do just fine, and once the green cast is gone, your image will have much better color calibration.

Thanks RFD & Jrista.

That green cast was quite bad and the clarity is also very harsh. My laptop screen is not calibrated... so now that I've gotten to process with my desktop, the colors should be more accurate.

Here is the updated image. I selected the 100 best frames and stacked them using 3x drizzle on portions of frame using 12 portions. I then Stitched the resulting 12 images into a single image and finally cropped in to get roughly 85MP for the final image. (I scaled down for web use)

nice, new edition far better

Very nice shot. Well done telemaq76.

thanks click, just done this morning with moon 88%, ngc7000. Half time was done at night end ,with moon very low on horizon
41 light 165 sec, 28 dark, 15 flats, 100 offset

Awesome. Very impressive picture.

Wow, the depth is great.

 

[telemaq76]

thank you for feedback, here is the same ngc7000 with 500mm
finally a long night with no clouds. not great with the 85%moon but better than nothing

Lovely shots telemaq76!

I have no hope for the next month or two. The monsoons are in full swing. I will attempt in October.

Here is my first stack of Lagoon and Trifid:

Here is a wide-field shot of Scorpius Constellation including Rho Ophi Molecular cloud. I struggled a bit with my flat and dark-flat frames giving me problems so I stacked without them and manually removed vignette with radial gradient. The color was a bit off though.

Anyway, I edited to try and give as much color and detail to the molecular gas clouds. I was particularly interested in pulling some detail out of the nebula around Jabbah (IC 4592), which was out-of-frame of my previous wide-field shot of of the Scorpius region. I also wanted to get good saturation of the reds on the Cat's Paw Nebula:

This might not show the galaxy far far away. But it adds some depth to the stars. Hope you guys like it.
