My goodness, what a helpful video. Clear-as-a-bell introduction to what for me is a new way to study the sky. If I taught astronomy in university I would incorporate this into introductory astronomy. Also, I imagine Sky & Telescope magazine would be interested in having you create an article on this. Who knew? Thank you!
Thanks for the kind words Dan! I'm glad that you found it clear and helpful. I went back and forth about how detailed or complex a tutorial I wanted to create so I'm glad that I settled on this particular workflow to focus on.
This is awesome. I've always been interested in astro and deep sky astrophotography but have always been barred due to location, finances, etc. This is a great way to get all that and still feel like it's a 'you' photo since all the edits were done by you. Thanks for showing the process - it's not as difficult as I thought!
You can also make your own "Advanced Observations" where you actually program in all the desired information for a specific telescope: which object in the night sky, how many exposures, what filters, how long exposures should be, etc. and they will schedule it to be shot on the telescope of your choice.
If you are interested in deep sky photography on a budget, take a look at the Nebula Photos channel. th-cam.com/channels/O_gBdHekc74feh0bWqKJ1Q.html It is suprising what is possible with basic photography gear and from sub-optimal locations like cities.

if you just wanna process, can also process hubble data for free , big part of the fun here though is capturing the image which you miss out on via telescope live and so may as well skip to processing some free quality data
Great video. I did not know about Siril software. I understand that Siril uses non-linear alignment of frames. I just bought my first mono camera with filters. I used so far only Photoshop for processing of my mono images. When I do Auto Align of Layers, stars from frames with different filters never align well in corners. I guess that this is because Photoshop is using only linear alignment algorithm.
Wow. I've been dabbling in deep sky using my DSLR on a tracker, but been a bit disappointed in the image quality and the $$$$ needed to get something better. I'm definitely going to try some of the Telescope Live LRGB images. Good job explaining the SIRIL basics.
Thanks Jeffery! I think that Telescope Live has a ton of value, especially when you factor in the quality of the images that you can create from their telescopes. I've also been learning to process HSO (Hubble Palette) images... hopefully for a new video in the near future. I really think Siril is one of the coolest pieces of open source software that I've used. I think that it's really approachable for someone new to astrophotography and that's why I chose it for my processing.
Extremely informative tutorial. At what stage are calibration frames introduced into the process? I have been using SIRIL for awhile, using scripts, modifying scripts etc. and find it to be very good. My sessions to date have been broadband only with an unmodified DSLR. Only a few days away from the arrival of a new dedicated astro camera with dual band filter. Glad that you introduced me to Telescope Live. Thanks.
I've owned the Vixen Polarie, and I also have a MSM tracker. I personally find the extra weight, shooting complexity, and cost to not always be worth it for the majority of how I shoot (lenses 100mm and shorter). I like my camera kit to be simple. In that range, multiple exposure stacking on a fixed tripod can still make comparable images with similar integration times. That said, as soon as you start getting to the long end of that range, (100mm+), a tracker starts making a lot of sense since untracked exposures start to become too dark when trying to prevent star trailing.
Hi, thanks for this tutorial. One thing I missed was how to align the final Luminance TIF with the RGB tif. Could you post an addendum explaining this?
Since this was just using 5 separate crowdsourced one-click observations, I was able to collect all the data for this tutorial with the standard telescope live membership and I didn't need to spend any extra money over the monthly price of the membership. Since I have a Gold Plan and the data was collected over 2 months, it suppose it would cost about $100 ($49/mo). That said, you could also collect the same amount of data over time with their basic ($4/mo) plan if you check for new observations every day. I've also been able to make about a hundred more observations in addition to the 5 that were used to create this video... so that makes the value of the service feel a lot more attractive. I have a future custom $200 advanced observation in the works of a custom chosen night sky object. That one is scheduled to complete in a couple weeks so look out for another video about my experience using their Advanced Observations part of the service.
First video I have seen on Siril that tackles monochrome filter. But, I must have missed something huge. Did not see any darks, flats, or flat darks???
This is true indeed these images are calibrated. But in the case they are not like for instance if someone did their own imaging how is calibration done with LRGB images. Does one need to have separate flats,biases and darks taken with each filter separately or one set for all filters would do. And then how are these processed in Siri. I could not find anything practical in Siri’s tutorials they all seemed rather complex. Your Video was really excellent I must commend you on your work to share.
Hi Ian. Very interesting video. As a new astrophotographer, can we use telescope.live to process solar system objects such as planets (they are not deep sky objects) ?
Yes, it is possible, as far as I know, to use their "Advanced Request" feature to schedule shooting of solar system objects. This feature of Telescope Live does require the purchasing of credits, however in order to buy time on the telescope of your choice. I've not yet seen any of the more accessible "One Click" observations that were solar system objects.
@@LonelySpeck Thanks for the reply. Maybe because they use ccd sensors to capture images from deep sky, whereas CMOS are better for solar system planets
@@jeromec3725 I think it's in large part due to higher demand for deep sky stuff... they likely get a lot more requests for shooting nebulae and galaxies than they do images of Jupiter or Saturn. I also think that since the telescope cameras they've selected seem to be designed for long exposures rather than video-based lucky imaging capture, they might be just better suited for shooting nebulae than they are at shooting planets.
Easliy the easiest SIRIL demo I've found on YT.. even tho I'm not using Telesope live or luminescence files... thank you

As someone who relies on telescopes for dark sky imaging, I find this very interesting! Thank you for sharing this ✨

Excellent video in every way. I do wonder how the luminance stack got aligned with the others, you left it out of registered stacks sequence...

Thank you so much. I use Gimp instead of PS but the advice is still relavent. Btw SIRIl now has a good curves tool in the latest release
Super cool video. Will have to check out telescope live since deep sky is a challenge for me geographically. Thanks for another great tutorial!
Great final image! :) One little thing to consider and can make it even better is reducing the green in the background and making it more neutral. :)
Ah yes. LRGB with a mirrorless camera and a lens. Thank you youtube I needed this
What an absolutely amazing video. Thanks for sharing your knowledge on this.
Really very good video. Thanks!

Really excellent video and presentation, I have learnt so much!
Thank you for this video! Is there a way to process SHO images with Siril?
Nice video! Have you ever considered getting a star tracker?

thanks for this video it is helping me learn Siril a bit

Should be easy enough to just add it to that grb alignment step :)
Great Tutorial, You helped me alot!!!
Please do more DSO Post proccesin using this SIRIL and PS :)
Can you do a video for Halpha, Oiii etc?
Extremely helpful, thanks!
How do you add Darks Flats etc for stacking?
Fantastic Astro Video, thanks for sharing
Great video, very very helpful!!!
Mind blown. Amazing work! How much did your fantastic image of Rho Ophiuchi cost?

@@LonelySpeck Thanks for the update. It was very informative and helpful. It makes it seem much more affordable and plausible. Cheers!
Amazing video thank you!
Thanks a lot. Great help.

Telescope live images come pre-processed with dark/flat/bias applied.
This is true indeed these images are calibrated. But in the case they are not like for instance if someone did their own imaging how is calibration done with LRGB images.

That was fantastic. Thank you 1000x 👍🏻
Use the stand alone Starnet ver 2 to remove stars ✨😊❤️👍🏼
can this tool be used to process normal milkyway landscape？if can please make a tutorial，need it～
soo your using cal.fits, how do I get Calibrated files I presume I have to calibrate all of them first with darks flats and biases?

I cant use curves because TIF image is in 32*
What is the L RGB ?
@@refetastro luminance, red, green, blue
I’m lost here
I didn’t know siril has all this options.
Deep sky stacker...is a bit easier in process that Siril....
No. With scripts siril is easier as DSS, and result is better.
rent a telescope? why not just download pictures from nasa? cheaper, easier, better, faster, stronger, cooler.
