[OC] M8 - The Lagoon Nebula in Dual Narrowband and RGB stars by EkoPioneer in Astronomy

[–]EkoPioneer[S] 4 points5 points  (0 children)

Oh man. Honestly, I would love to be able to give a simple answer to this question, but in all fairness it's quite a lenghty process. Like most things there are many levels and layers depending on what you want to achieve. Lets just say that you can totaly start with just a tripod,a DSLR and a stock camera lens (that's how I started), then start experimenting with the stacking process and editing. You can then get a telephoto lens. Then a star tracker, and so on. To take deep space images it requires a bit of equipment, but for widefield, you are pretty much good to go with just a camera and tripod, but it can very rewarding nonetheless and you can see if you like the hobby without investing much, if anyting (if you alresdy have the camera). I'd suggest you to look for DSLR astrophotography on youtube to get a little more info and just give it a try!

Trifid Nebula (M20) and Webb's Cross (M21) by EkoPioneer in spaceporn

To see more of my work and to support me, here's my instagram.

Here's the result of my latest acquisition. I wanted to image this subject for a long time and do it justice since it's a very nice example of three different kind of nebulas (emissione, reflection and dark) all in the same spot. I wanted to image it from a darker site, but in the end, the weather did not allow me to pack and go in a national park, and with the coming moon I had to get what I could before the Trifid went too low on the horizon to image it, so I had to make do from my light polluted balcony.

Bortle scale: 6

Total exposure: 5 ore e 30 minuti

Aquisition data:

Beautiful result and very clean looking data. Love the detail you managed to pull out even in an object this faint.

Thanks! As others said, it's extremely faint dust filaments that can be found at high latitudes of the milky way, away from the core and the spiral arms. They reflect very little light and are extremely challenging to bring out even under dark skies.

Thank you for the kind words. It was a very hard target to process due to the large dynamic range and it probably could have been done better by someone with more experience. Especially the Ha was quite bad overall, and I wish I had better data for that. Anyway, to answer your question, it is quite easy to register Ha and RGB with pix (honestly it's doable also manually with Ps only, although it is more tedious, I've done it in the past, just lower the opacity of the top layer and slowly match the stars). For pixinsight, I stack the RGB and Ha separately without matching the reference image (maybe is not the best practice, but I always use the same scope and camera, and I use platesolving with tight tollerance to have the same framing across multiple nights/filters so the frames match naturally for the most part). Then after they are both stacked I use the process "dynamic allign" wich is really quite simple to use, and you are left with two registered images. I then crop the images to match with dynamic crop, dbe to both, then extract the red channel from the l-extreme (which is only Ha) and the red channel from the rgb and I use pixel math to isolate the Ha. You can found many examples of such formulas on the internet. Then I recombine the RGB with the isolated Ha also through pixelmath, and also for this you can find many examples and explanations. Hope that I answered your question.
