It is important to us to present to you our astrophotography taken thanks to the advice we give you in our training. Indeed, our teaching comes from the regular practice of astronomy and we regularly update our knowledge.

Our favorite targets are those in the deep sky because of their beauty and impressive size. These are objects accessible to photograph and whose final result is very close to what space telescopes, like Hubble or James Webb, can achieve.wind observed and captured unlike planetary astrophotography, the result of which is not always up to what we can see in specialized journals. Our goal is to obtain a result as close to reality as possible and to be proud of it.

To achieve the results presented below, we use various restrictive filters such as L-eXtreme and L-Ultimate from Optolong. This makes it possible in particular to highlight the alpha hydrogen layers present in the galaxies and to create images of the nebulae in Hubble palettes, that is to say in SHO, by extracting the Ha and OIII layers from the L- filter. Ultimate and using an SII filter in combination.

Exposure times vary from one target to another depending on their luminosity, the presence of very bright stars in the frame and the filter used. However, we do maximum exposure times of 600s on average (10 minutes) and minimum exposure times of 180s. Of course, this varies and we regularly experiment with longer or even shorter exposure times.

The material used is as follows:

- Skywatcher 80ed evostar bezel with corrector/reducer
- Zwo Skywatcher EQM-35 Pro and AM5 mount for the most recent images.
- Zwo 533mc pro color camera
- Zwo 120mm mini black and white guidance camera
- 120mm guide scope and zwo optical divider (OAG) for the most recent images
- zwo mini filter wheel (L-eXtreme, L-Ultimate, SII, UHC)
- Zwo autofocuser
- Asiair plus

The processing is carried out using the following software:

- Stacking and preprocessing on Siril and/or PixInsight
- Main processing on PixInsight
- Finishesaesthetics in Lightroom
