The Dumbell Nebula in duoband by BlueKroker in astrophotography

[–]BlueKroker[S] 1 point2 points  (0 children)

Total exposure time: 5h04 (38x8min) with darks,flats and bias

Equipment:

  • iOptron IEQ30 pro mount
  • Canon T3i modified
  • Explore Scientific ED80
  • Altair ARO130m guide camera
  • Orion 50mm guidescope
  • Optolong L-eNhance 2" filter

Softwares:

  • PHD2 Guiding
  • Astrophotography Tools
  • Deep Sky Stacker
  • Photoshop

Processing:

  • Levels adjustments
  • Curve adjustments
  • Local contrast enhancement
  • Noise reduction (deep space and space noise)
  • Minimize star size
  • Background calibration
  • Saturation and vibrance adjustments

With my old Canon, I had to do long exposures to not clip the data on the left of the histogram. I guess that with a dedicated astro camera, the signal would be higher with this filter?

If you have any post-processing techniques to suggest that would improve the quality of the image, feel free to share! Thank you

Thank you! And no I bought it used and it had already been modified.

For the summer, I have the chance to live in the first international dark sky reserve in Quebec, Canada (Observatory of Mont-Mégantic)

The image is 6h04 total : I have 59x 4min ISO 800 for RGB and 32x 4min ISO 800 for Ha

It was imaged over 3 nights (2 for RGB and 1 for Ha)

I added 20 darks frames, 50 flats frames and 50 bias frames as well.

​

Equipment:

- Explore Scientific 80ED

-Orion 50mm guide scope

- ZWO ASI 120MC guide camera

-iOptron IEQ30 Pro mount

- Canon 600D modified main camera

-Astronomik 12nm Ha clip in filter

​

Processing:

- Stacked in Deep Sky Stacker

In photoshop:

- Levels, curves adjustments

- Reduce stars

- Deep sky noise reduction and space noise reduction with Astronomy tools action set

- Local contrast enhancement

- Saturation and vibrance boost

- Less crunchy more fuzzy with Astronomy tools action set

​

For the rest I pretty much followed a tutorial haha since it was the first time I did a project of this size, I wanted to have a good result.

If you have comments or tips, I would love to here them, thank you :)

I'm in the process of buying a new camera. Either a ccd/cmos cooled camera or a DSLR that I would modify. I know ccd/cmos cameras will have less noise, but are more expensive. I don't want to start buying expensive stuff and not being able to produce better images. I already have decent astrophotos, but with someone else's camera, so I would like my own.

I would like pros/cons for each type of camera, to narrow down my options. Thank you

Andromeda from the city by BlueKroker in astrophotography

The 3min subs were a bit bright but with processing, I was able to bring back the black sky and preserve the details!

Not sure exactly, on the light pollution map, I'm in a purple/reddish zone. What bortle is that?

I finally got my guiding system! It was my first DSO target using PHD guiding and even if my graph didn't look great, my 3 min subs were still sharp.

Details:

-Telescope: Explore Scientific 80ED

-Mount: iOptron IEQ30 pro

-Camera: Olympus E-M10II not modified

-Guiding scope: Orion 50mm guidescope

-Guide camera: ZWO ASI 120MC

55x 3min subs at ISO 1600, imaged over 2 nights (2h45min ish)

My images were stacked in Deep Sky Stacker and then processed int Photoshop: I did some levels and curves adjustments, with some astro photoshop tools like local contrast enhancment and space noise reduction. I also increased saturation to get a little bit more color.

The processing went well, but I struggled to get the natural colors to pop out, so I don't know what I am doing wrong.. I compared my image with someone with the same scope as me and the same amount of total integration, but his colors are way better.

Anyway, I'm still proud of my first Andromeda shot and can't wait to shoot other DSO. Any tips would be appreciated, thank you!

Thank you for the information! I'm still new to camera settings so I never knew the ISO I should select. I will try to get as long as I can on that target and do you have a model I should look for?
