Ik zou niet weten waarom het niet zou werken, maar als u al eerder problemen heeft ondervonden is het misschien verstandig om het aan de klantenservice te vragen. Je kunt ze via dit mail adres bereiken: support@moveshootmove.com Hoop dat dit helpt.

or maybe preprocess separately, then create a master sequence from multiple sequences, and stack it

Thank you! Regarding your question your on the right track: 1) Flat darks and bias frames serve the same purpose and can be used intergeniably. So if you have shot flat darks instead of bias you can just process them like they are bias. 2) If the data is split between different days you indeed process them in different sequences. Then when you have your preprocessef lights (so pp_lights) you put them all in one big sequence. Register all of them and simply stack. Thanks for your questions 😁

Yeah, Siril takes some getting used to for sure😅😂

Hi, thanks for your question. So all it does is multiply thenstars by 2. Basically all pixels become twice as bright. That way we see more stars in our final image. But this value is for up to the user to decide.

Indeed the main advantage of software like Siril is that its free. Which is amazing if you are a beginner. APP is an amazing piece software, however for me it is not worth the money at the moment. About the dust modes, I was struggling with so much dust on the glass Infront of the sensor that is started moving when the telescope moved. This made it impossible to properly calibrate out. Cleaning the piece of glass resolved the issue. - Stefan

Amazing to hear you found the video useful! Thank you for sharing your experience 💪

Sorry about that. Yes I agree, the video in general feels a bit rushed in my opinion. Might redo the entire thing when I have time.

I have no clue to be honest. But you could start by trying to pinpoint the problem. For example by first slipping calibration and then see if you can register the frames. After that I think it would be best to make a post on the Siril discussion forum. Hope you figure it out, Stefan

@@stefan_astro We did figure it out. There is a setting on the APT camera selection tab for "Color FITS Preview (de-bayer)". I had the box checked (because I had previously been using an OSC camera) and this caused APT to insert a Bayer pattern entry into the FITS file header causing Siril to interpret the files as RGB. Unchecking the box corrected the error and Siril now recognizes the files as being monochrome. Thank you for getting back to me.

Nope. It's a C9.25. Sitting between the C8 and C11. It's a really nice scope, just a bit too heavy for the heq5

@stefan_astro hmm Planning to get a c8 edge hd for my eq6. What would be a better choice for ap ? The 8 edge hd or the c9.25 ? I will be using a 585mc pro or a 600d dslr Thanks

Both are incredible scopes! I do think the C8 will be a little easier to handle, but the eq6 should be able to handle both. You could also ask Martin Schoenmaker (Here on CZcams). He recently switched from the C8 to the C9.25 and might this be able to give you some more insight.

I'm not sure if both of them are open source, but luckily both are free to download! This video simply details how you can start Starnetv2 from inside of Siril. Doesn't cost you anything.

@@stefan_astro It's not free. I tried to download it several times and it always gave a download error, then I tried to search the internet for some information and finally I found some forums where they confirmed it

I'm sorry I don't understand your question.

I'm glad you found the video useful!

Glad you found it useful!

Glad it was helpful! And clear skies to you too! - Stefan

I have done so since. Made a massive difference indeed. Was really quite scary tho😅 - Stefan

I'm glad you found the video useful! Good luck with processing. Please tag me if you post your pictures somewhere. Would love to see the results💪 - Stefan

Glad you found it useful!

Glad the video helped you out! Good question about the flats. I suspect that it had to do with some sort of dew or something on the sensor which didn't stay in the same place between imaging and the taking of the flats. However I'm not sure. Luckily since I cleaned the sensor the problem is absent. - Stefan

There is a lot of things that could be wrong, but I would suggest you start by looking at the error message. Often Siril will just tell you what is wrong. If that doesn't help, reinstalling Siril often does the trick. Hope it helps. - Stefan

@@stefan_astro yeah, later I realised i need to first register those images so i can stack them. It worked. Keep making such videos 😄

I have no previous experience with ERDAS, however a possible cause for your problem could be that you saved the final image in 32 bits instead of 16. Which results in a dark image

Glad you found it useful!

Thank you! Yeah the laser collimator isn't great. When looking at an unfocussed star after collimation with the laser collimator I can clearly see that it's of. In addition it provides no way of really collimating the secondary properly. Which is why I'm now looking for a new way of collimation. About the Ps raw, I'm not really sure what you mean. I vaguely remember the name, but I'm not sure if I even have it installed nor do I remember what it does. - Stefan

@@stefan_astro Hi Stefan have a look at the cheshire collimator as mentioned previously.

I will, but I did hear some mixed opinions on them. Might go for some sort of webcam type thing. Need to look into it further tho.

Indeed this technique is mostly used for galaxy's, however can also definitely be used for nebulea. But as far as I know there isn't a specific video about processing nebulea in particular. Maybe I should make one😉 - Stefan

Glad you found it useful! Gimp is definitely a great program. Have used it a lot in the past as well.

@@stefan_astro Yes, Gimp is great but I need to improve my workflow. Right now I stack in DeepSkyStacker for the (LRGB-HA) and combine the channels in GIMP manually. It's a total pain with the chromatic abberation and the weird lens distortion tool. Rotation is also an issue. On top of that, I always feel like I'm losing a lot of data trying to adjust the curves for the color values. 32bit image, the histogram is like a 1 pixel wide line. There is no option to zoom in on that, so it's really painful to get it right and requires a lot of iteration ^^ Not saying it's not possible, but I want something more straight forward and this seems way nicer :)

Thanks for the tip! I will for future videos. - Stefan

Glad it helped!

Glad you found it useful! - Stefan

Definitely! Will try to make one soon!

Thank you!

Klopt inderdaad 😂

Thank you!

Hi Ross. It sure can. The process of preprocessing is the exact same. Although it should be noted that the processing of the combined SHO image will be different. Mostly because balancing the different narrowband images is rather difficult. If you want I could make a tutorial about the combination. (I will just need to get my hands on a SHO dataset as I don't own all 3 filters myself) - Stefan

That would be great thanks Stefan !

Got a SHO image of the Elephant trunk nebula using your excellent tutorial Stephan. If you want I can e mail you the image if you want?

That would be great! Will it than be ok if I use it in the SHO video? E-mail: stefan.astrophoto@gmail.com

@@stefan_astrosorry just read

Thanks for your comment. Not sure what you mean by rc1? - Stefan

Yeah I believe there are 2 types of focusers. Quiv got a different one than I did. Which is weird and I don't really understand the reason for it. But it is good to keep an eye out for to make sure you get the right one. I really quite like mine. Only complaint thus far is that it makes some noise during focussing. But it focuses flawlessly nonetheless.

​@@stefan_astro bene! Sono contento che funzioni bene! Grazie per la risposta 😊

Yeah from the Netherlands indeed. Yeah Wido makes some great content!

Sorry to hear that. But I suspect it has something to do with the fact you are still running Windows 7. - Stefan

@@stefan_astro Stupid computer. Thank you.

Thank you!

Glad the video helped! Clear skies. - Stefan

I'm sorry, but I have no clue what could be causing your issue. But you could try it with the latest official build of Siril. (1.2.0-beta2) Maybe that will work better. -Stefan

@@stefan_astro thankyou will try it tonight🙂

Thanks you!

Thank you! Really looking forward to the first light aswell!

No my bank balance isn't very happy😂, but I am😁

Wonderful! Did you also add the oxygen data? Are there even any o3 regions there?

@@stefan_astro not for this one but I played a bit with pixel math using Ha and O for Rosette nebula and that also looked good

Thank you! Yeah Siril is able to combine all sorts of datasets. Even from completely different setups. The only thing you have to think about is that you calibrate each dataset seperately. - Stefan

@@stefan_astro Thank you! I'm completly new to Siril. I have a stack of 2 and 3 min light fram i would like to combine. I should then follow all the steps for both the 2 min stack as well as the 3 min stack? How would you suggest afterwards? Thanks

@@stefan_astro I dont have the pre-prossing tab ? Version 2.1.0

So first calibrate all of your lights in 2 seperate folders, one for 2 min and one for 3 min (so darks, flats and bias (if you miss any of these don't worry about it to much)). Then Siril will give you pp_lights_x.fits with x being some number. Which you put in to the conversion again to create a new sequence. After which you can register the images and stack them. Concerning the preprocessing tab being gone, I believe they changed the name to calibration. Hope this helps! - Stefan

Have you updated to beta version 2? So 1.2.0-beta2. Because in beta1 Starnet doesn't work properly. Hope this helps. - Stefan

@@stefan_astro I have changed it to beta2 but for some reason siril can't find the statement file even though I have it installed.

Have you installed the command line tool? Cause I heard of someone else who installed the ui tool and that didn't work. So make sure you have the correct version of starnet installed and also told siril where to find it. I can't think of anything else at the moment, but I hope you figure it out. - Stefan
