Siril - registering and stacking images

[Tenor Viol]

Looking for some ideas / assistance. 

I use a Mac and I need to stack images. Following suggestions I have downloaded Siril. So, before eI go any further what have I got and wha am I doing?

• Nikon Z6 camera shooting RAW files
• 5 images of Neowise
• Siril v0.9.12

I have tried two methods: DSLR script (no dark/flat/bias frames) and using file conversion to create FIT files, registration, stacking.

If I try using single or global star alignment it says it can't - no stars (I have played around with Analysis Dynamic PSF). If I use 'comet/asteroid' option, I get a complete mess per the attached. 

I'm either missing a critical step, or misconfiguring something somewhere... any ideas?

Ron.

there is a comet stacking procedure to follow here, PDF at top

https://discuss.pixls.us/t/comet-registration-tutorial/16248/5

it works pretty well

you are missing several important steps

I got this from my wide field stack, on my second try once I found the PDF as the first go without it was a mess too, window frame on left and a static mount

I could take this into a photo editor and layer in the foreground and crop the edges etc.

Thanks. I found that PDF doing a search earlier, but it didn't seem to be doing anything I hadn't done? I was confused by the 'sequence' option. I'm using a DSLR so I thought the first step is fie conversion to get from RAW to FIT? Not sure what 'sequence' step is doing?

[Tenor Viol]

I've put in the sequence step and it says it succeeded, but the registration step still failed. The PDF looks like it's processing a mono image whereas I'm colour, so it's selected green channel for this (channel #1):

Select debayer on the conversion tab

[happy-kat]

You need to use single star to register and spot it on first frame

[Tenor Viol]

Hi @happy-kat - I did have debayer ticked... I don't seem to get one frame coming up? But I will delete everything and try again later. Unfortunately I've got a busy day of cooking today... so might be a while.

I can't try a process until tonight, I'll see what else I've done when doing it. My 55mm works but I'm not winning on my 85mm but those images have less defined stars

Mine are at 145mm

[happy-kat]

I've got some new data to play with which has better stars and no window...

[Tenor Viol]

I'm coming to the conclusion that there are very few users of Siril on Macs. There is not much in the way of videos online either.  

[happy-kat]

I have got some fiddling to do, lost the colour in the new stack of last night's data but I can make out the split tail happy to have got that

Maybe  @alacant Can help ?

Hi everyone

Sorry. I'm being thick i know, but where is -the link to- the files that the OP is having difficulty with?

@Tenor Viol You have a very old version of Siril. Please update to the newest. It looks like this:

 

HTH and clear skies.

Hi - thanks I will check - I only downloaded it last week off the Siril site.... Here is one of the RAW files: https://drive.google.com/file/d/1MLLm6kVJ7cWz6LR16sD-p8dcttobBeDq/view?usp=sharing

 

[Tenor Viol]

Quick update. Siril is v 0.9.12 and when I click on updates it says no update are available. 

[happy-kat]

I'll check the version I'm using. I should add I can see using fitsliberator that the stacked file does have the R, G anr B channels so I'll use the compose module in StarTools.

Sorry. I'd forgotten. Mac is several versions behind.  Not ideal but it should still work. 

Do you have access to a Linux box?

Do we have the files somewhere? I'll see if I can try with an older version.

Cheers

Odd... should have been a Google drive link.... I think they've been playing with how it works, let me re-send....

Yes - just looked na dGoogle have changed how it works...🙄

Hi

OK. Convert the NEF(s) to tif(s). Mac should be good at that:)

Then import to Siril. Don't forget to debayer;)

Works with all versions.

HTH

 

[Tenor Viol]

OK - I thought Siril's file conversion was supposed to handle that? I can get Photoshop to do that.

Siril's file conversion

Conclusion: z6 nef doesn't work with your version.

The workaround does however.

Tell the developers? They usually fix stuff the same day.

Cheers

[Tenor Viol]

Ah - interesting. I would have expected it to complain... The Z6 has been out a couple of years now.... Will do.  

[don4l]

Does anyone know why Siril won't register without the date?

Is there somewhere that I can put the date?

I've got some Canon files (CRW and jpeg) that I would like to stack.
