Bill-T Posted 10 hours ago Share Posted 10 hours ago (edited) I am new to astro but have bought Zerene ( https://zerenesystems.com/cms/stacker ) and used it successfully for macro photography but I'm sure the requirements for astro pictures are more specialised. Any recommendations for a starter software package please? Edited 5 hours ago by Bill-T Link to comment Share on other sites More sharing options...
DaveS Posted 10 hours ago Share Posted 10 hours ago Deep Sky Stacker is free and pretty damn good. Worth starting out with before spending real money. Link to comment Share on other sites More sharing options...

I use Zerene for macro photography and it's excellent but it won't work for stacking fits files in astrophotography as it only works with tiff and jpeg files, if you are capturing your astro images in those files it might be worth a try as you already own Zerene. As mentioned DSS works well, I stack my images in Siril and 99% of the time it's perfect. For the other 1% that Siril rejects I've used DSS and it works well for those, just one of the many mysteries of astrophotography processing!

Elp Posted 9 hours ago Share Posted 9 hours ago (edited) DSS for simplicity, Siril for better control and also post processing options. Both free. Edited 9 hours ago by Elp Link to comment Share on other sites More sharing options...
ONIKKINEN Posted 8 hours ago Share Posted 8 hours ago If you are patient and have some time to spare for learning, then Siril as it is very good but a bit difficult for a total beginner to use. Otherwise go with DSS, its very simple to use and does an ok job at stacking. 1 Link to comment Share on other sites More sharing options...
LaurenceT Posted 8 hours ago Share Posted 8 hours ago I'm obviously bored this morning with time on my hands, I batch converted some fit files of the Eastern Veil nebula to jpegs in Irfanview and then stacked them in Zerene. As you can see the final result is less than stellar (pun intended). Link to comment Share on other sites More sharing options...
bottletopburly Posted 7 hours ago Share Posted 7 hours ago Siril is a fine program, Deepspace Astro has a lot of Siril content, scripts are easy to use too in Siril 1 Link to comment Share on other sites More sharing options...
DaveS Posted 7 hours ago Share Posted 7 hours ago If you're willing to spend money, and don't want to get involved with PixInsight then have a look at AstroArt v8. It will do pretty much everything including capture. 1 Link to comment Share on other sites More sharing options...
Albir phil Posted 7 hours ago Share Posted 7 hours ago Yea Deep Sky Stacker, it dose the job and so easy to use and it's free Link to comment Share on other sites More sharing options...
PhilB61 Posted 7 hours ago Share Posted 7 hours ago Deep Sky Stacker is free and easy to use, SIRIL is also free and much more capable and flexible but requires a bit more effort to master. 1 Link to comment Share on other sites More sharing options...

TiffsAndAstro Posted 6 hours ago Share Posted 6 hours ago For a beginner (as I am) siril. Name 4 folders correctly, lights, darks, biases, flats and put the correct files in those directories. Launch siril, click scripts, choose osc. Wait for stack to finish, will depend on how powerful your pc is. I think dss is a bit less simple for a complete beginner but I still use it before stacking to help me rate my sub quality. Link to comment Share on other sites More sharing options...

michael.h.f.wilkinson Posted 5 hours ago Share Posted 5 hours ago I have used DSS, but didn't get on with it. I now use Astro Pixel Processor (not free, but not very expensive either), and much prefer it. It is far more intuitive to use, I find. 1 Link to comment Share on other sites More sharing options...
Paul M Posted 4 hours ago Share Posted 4 hours ago 2 hours ago, TiffsAndAstro said: For a beginner (as I am) siril. I found Siril to be overly complex for a simple stack. Counterintuitive in fact! Indeed, any software that needs the instructions reading just to open the virtual box loses me very early in the mating process!! 😇 We just sat there looking at each other waiting for one of us to do something. So my vote goes to DSS. I do most of my stacking in ASTAP nowadays, but it does need a bit of setting up to access it's many other functions and might frighten away a new-start imager.

TiffsandAstro - You really should try manual stacking in Siril which gives you access to the plot tab. You can then view sub quality on different criteria including FWHM, roundness, number of stars, background etc in a really easy to see graphical form (or table if you prefer) and excluded them from stacking directly. I'm sure it would be quicker and easier than culling via DSS. Alternatively I'm pretty sure I could provide an osc script so it will process everything but stops immediately before stacking so you can review/cull before stacking if you want to continue with scripts. 2 Link to comment Share on other sites More sharing options...

I sort of do that (mostly) when stacking multiple sessions. To have a quick look see what I got osc script is ideal. Confession time, I still haven't fo a manual stack of one session, apart from for comet A3. So I'm getting nearer Siril only offers fwhm to compare on the plot though, while dss gives me that, %bacground and #stars in list I can sort. That's a very kind offer to make a script for me, but I'd rather get used to manual stacking. Link to comment Share on other sites More sharing options...

Nope, star count, roundness and background level is also there. As well as the "weighted FWHM" number which is a combination of FWHM and star count. For background level to show up you might need to run dynamic PSF on the registered data first. Been a while since i checked that as i am watching the data as its being captured so dont need to check afterwards but i think Dynamic PSF was required. 1 Link to comment Share on other sites More sharing options...

You're right, but i have to add multiple conditions to the rejection algorithm. I use dss first just deleting clearly bad frames like only 5 stars or really high fwhm or background. When stacking I'll usually only reject by one, usually fwhm or stars. Might be worth me trying multiple conditions when stacking in addition to dss first. Also dss has scores. I like scores.

You can drag a selection box around the bad subs in the plot tab and reject them that way. No need to set the specific rejection filter since you can go through all the stats and reject as you see fit and stack whats left. The wFWHM value is kind of like a score, you'll like that as much as the DSS score. Give the plot tab an in depth look, its one of the best features in Siril IMO. 1 Link to comment Share on other sites More sharing options...

I didn't realise that. When stacking multiple sessions, you can easily see if one session was better or worse than the others just from looking at the plot. I certainly find the graph a much better way to visualise this than just a list of numbers. 1 Link to comment Share on other sites More sharing options...
