This page is a collection of useful links for astrophotography.
La ferme des étoiles (Gers)
This asociation allows astronomy courses of different durations and for all levels with a high quality seeing site that includes many materials with a 620 mm telescope. I have personally followed a 4-day course that left me a wonderful memory, both on human factor than technically.
This association offers courses and tutorials in astrophoto (the covered domain is from the acquisition, pretreatment and processing of astronomical images) They are taught by "expert" amateur astronomers who are recognized in the middle of astrophotography.
For those interested in photography (and not only astrophoto ;-) I recommend you the Nationnal Higher School of Photography in Arles that offers courses for all levels and where I had the chance to perform a very useful 4-days training to master the reflex camera in all conditions with also an introduction to the image processing with Lightroom.
Remote control & Acquisition
ASCOM Project - Standards for Astronomy
This platform provides a set of "unified" drivers in order to make the communication easy beetween a various astronomical software and a large set of materials (mounts, cameras ...) It is a mandatory prerequisite !
The EQMOD Project
This softwares platform provides a set of tools that allow different controls of a compliant equatorial mount with a PC.
For example, you can connect from your home throw your WiFi network (if distance permits or with an additional access point) in "remote desktop" mode on the laptop which is itself directly connected to the mount and perform well (especially during winter ;-) the control and snapshots on differents deep sky objects.
Another tool offered by this platform can analyze the periodic error of the mount from a record file (PECPrep)
Cartes du ciel - Skychart
Planetarium be able to create your own maps of the sky but above all, the best asset is to driving an ASCOM compliant mount.
Although this guidance software is no longer maintained, it is a reference in the field. It allows to take into account an important game in declination for the mount that does not PHD Guiding V2 and it is with Guidemaster I get the best tracking for my mount that begins to have significant mechanical games over the years.
Open PHD Guiding (PHD2)
Formerly "PHD Guiding", the V2 version thoroughly reviewed this guidance software that remains easy to use. It should be noted that this guidance tool is much more resource-intensive than its cousin Guidemaster.

Astro Photography Tool (APT)
It is essentially an acquisition tool that allows many actions to be performed, most of which are automated: camera temperature management, motorized filter wheel, focus, centering of known objects, creation and execution of acquisition plans with possibility of scripting, modification of the previews, creation of flats, ...

This tool is able to manage both aquisitions and treatments. It has many built-in scripts including a very useful one that can convert a series of images in FIT format to standard formats to be able to view and sort acquisitions quickly.
Simply the reference freeware planetarium.

Softwares & Tools
Very good freeware of automatic pre-processing and processing of astronomical images with frequent updates. Ability to use native scripts from the application or downloadable from the community.
The Sirilic tool is very practical because it allows you to control the Siril application according to an advanced configuration and is able to manage several sessions with several filters automatically.

Lien : Sirilic tool
The pre-processing and processing astronomical images software of Christian Buil. Easy to use for the usual pre-processing functions but also very complete with its many advanced features. It has the great advantage to allow automated processing for most functions that are scripted and can be chained with or without interruption.
Reference software for pre-processing of planetary images (movies or photos) Its best asset is the treatment of wavelet deconvolution that provides sharpness and slightly noisy images.
Very good software for registration of the planetary images. Easy to set up and with an automatic mode by pre-treatment phase. Sorting the best images by quality criterion is its best asset.

Good tools provided as plugins to process astronomical pictures with Photoshop.
A good tool to use in Photoshop that removes much of the gradient from astronomical images.
Hasta La Vista Green
A good tool to use in Photoshop that removes the green chromatic noise from astronomical images.
Software I do not know well but capable of carrying several pre-processing steps including calibration images (white balance)
Startrails & Starmax
The both softwares allow to create star trails from a series of photos
Tool that allows the sort of images from the metadata contained in for compliant photo formats (available on all platforms). I personally use the Linux version that can be used through bash scripts.
This project proposes Python libraries and tools (under Linux platform) for astronomy. It allows for example to read the header of image files in FIT format to retrieve metadata.
