Our PixInsight Workflow 1/3: Stacking and Drizzle - DSLR Astrophotography M78

[@felipemacauliffe1528]

Thank you so much for your useful and great tutorial. I've heard a lot about drizzle in processing but never had the chance to really have a look on what was this about. Thanks to you now I'll start using drizzle in my processing. All the best, clear skies and shine on from Chile Cluster One Observatory

Finally some (new)user-friendly tutorial I've found :) Thanks and clear skies :)

[@LukeSmith-pp4hn]

Another great episode this is a great idear as info on processing is sparce .. looking forward to the next one much love guys

[@GalacticHunter]

Thank you Luke, Part 2 will be available shortly :)

Thank you John :)

Excellent work! All the images look great. Lets me know how far I have to go. Great job. Thanks for sharing!

Thank you Scott!

Hi i enjoy your shows when can we expect first light of your new zwo asi camera with mono processing?.

[@GalacticHunter]

We're waiting for some good weather to get out there and finally give the zwo a proper go! It's actually been snowing a bit here in Vegas...

Hey you guys hosting anything for Messier Marathon next month? Looking for as many star party sites in case I get rained out in Los Angeles! Thanks!

[@GalacticHunter]

Hi Victor, we don't have any plan as of right now but the Las Vegas Astronomical Society often meets to do the Messier Marathon each year. We might join them if we have the time!

[@viniguez487]

Galactic Hunter Sweet. If you guys ever need a spot out here in CA let me know.

[@GalacticHunter]

@@viniguez487 Good to know thank you!

[@Dances_With_Skies]

Thanks for the tutorial. I just have one question. Does the Batch preprocessing script debayer the images or does this have to be done first? The reason I ask is because the resulting image I get seems to be black and white.

[@bailesie]

I have the exact same problem

[@ADCar]

Are the raw files still available for practice? When I click on the link provided, only the processed file, M78 DSLR Master with Drizzle.xisf, appears to be available.

[@GalacticHunter]

We had to replace the raw frames with the masters because the raw frames were taking way too much space on the cloud, you can still use the master files to go through the entire workflow, just skip the stacking part

[@ADCar]

@@GalacticHunter Thanks for the response. I figured it was probably something like that but I just wanted to make sure I wasn't missing anything.

[@mjtechdad]

Great work

[@GalacticHunter]

Thank you Michael :D

[@jeffkuderna820]

Have you used cosmetic correction while stacking to remove the satellites/plane trails from some of the images? Any plans to go to NEAF in April?

[@GalacticHunter]

No we actually never use cosmectic correction (seems like the scrips takes care of it? not sure) but we should definitely learn that. As for NEAF, we can't afford to go this year but hopefully in 2020!

[@dgodiex]

@@GalacticHunter The sigma clipping, in the Image Integration parameters, takes care of satellites and other inconsistencies during the stacking.

[@GalacticHunter]

@@dgodiex Thanks for sharing, we'll give it a try!

[@dgodiex]

@@GalacticHunter I'm sure you're already did, that's why there are no satellites in your integrated image. Go to the Batch preprocessing window, go to to the Lights list, and check under Integration and see what parameter you're using. There are a few variations of the sigma clipping, but all of of them get rid of satellites among other things. Cheers! And thanks for for the videos. You two are awesome.

[@GarnettLeary]

Great idea.

[@thelordofcubing]

Can you do a giveaway Cause I need that zwo camera😂

[@triangulumpubg6295]

You giys ever thought about something like we send you our stacked image and you edit them in videos? :)

[@GalacticHunter]

Definitely if we had more time but with our schedules/work etc it's already difficult to make videos so maybe one day if one of us works on Galactic Hunter full time we could, that sounds like a good idea :)

[@triangulumpubg6295]

@@GalacticHunter fine :)

[@BrokenPik]

ISO 800 ?

[@GalacticHunter]

Yes

[@BrokenPik]

@@GalacticHunter perfect, im working on your M78... will post soon so you can judge me trying! Salut... a tentaux...

[@PorPor.T]

how did you get Drizzle files?
