Altazimuth mount and large number of subs

@anto74 Wow that is a really good result, even if it wasn't an AltAz telescope!!!

As for your question, you don't need all the intermediate _rm and _nm images. You can load all lights from a single session into APP and go straight to tab 6 and click the integrate button. No need at all to execute each step individually. APP will take care of that. And no need at all to save all intermediate results!

Thanks for the answer 🙂

Ok, I understand that the nm and rm files do not serve my purpose, maybe I have illustrated my question wrong.

Integrating all subs from the three sessions at once is very heavy...

For example, I photographed M42 on December 20th, 22nd and 29th.

In each session I shot 300 subs and 30 darks.

I divided each session into groups of 100 subs and processed normally (from step 1 to step 6) each sub session.

For each session I have therefore obtained three final lights (0-100 101-200 201-300).

In total I have 9 final lights (3 lights December 20, 3 lights December 22 and 3 lights December 29).

Now to merge these 9 lights together I load them in step 1 and go straight to step 6, is that correct?

When I upload them, do I have to select multisession or not?

Thank you 🙂

Hi @anto74,

Excellent result 🙂 ! thanks for sharing.

To clarify, the _rm and _nm are the RejectionMap and NormalizationMap which are only created when you enable these in 6) for analysis of how the data integration performed. These maps are only useful for analysis and don't contain any of your data 😉

Like Wouter, says, for an individual session, you can simply disable Multi-Session in 1) LOAD, load your lights and go to 6) Integrate and click on integrate 😉 All will go automatically.

Hi Antonio @anto74,

Indeed, to merge the 9 final lights, simply load them in 1) and go straight to 6). You don't need multi-session then. Multi-Session is only needed when you use different calibration files (dark, flat, bias, darkflat) per session. Since you have integrated them. Data-calibration is no longer needed and thus Multi-Session is not needed.

To possibly get beter alignment in your final result for your 9 final lights, try to 4) Register, enable dynamic distortion correction and disable the same camera and optics, because the integrations/stacks of the 100 frame batches are considered as a different camera technically. If the stars are already perfectly aligned in your result, you can ignore this advice 😉

Thanks, perfect!
