Bonjour a tous,
Il s'agit d'un cliché de la Nébuleuse de Rosette.
Je souhaitai tester un objectif un Objectif rapide (F/d4) de 300mm de Focale de la marque Pentacon.
J'ai monté cet Objectif sur l'Olympus E‑M10 Mark II avec le Filtre Neodymium Sky & Moon.
J'ai monté le tout, sur une monture AltAz Celestron Nexstar SLT.
Je trouve que le Filtre Contrast boost gère mieux le Chromatisme que le Neodymium.
A 5000 ISO, je trouve que les photo reste encore très belles.
Tout ceci montre que l'on peu pratiquer l'astrophotographie en ciel profond avec un petit budget. Même avec une monture AltAz.

Une chose importante a savoir:
Je pratique l'astrophotographie depuis mon balcon dans une cité. Mon ciel est perturbé par les remontées de chaleur des bâtiments.
Ainsi, en se déplaçant, on peu faire beaucoup mieux que les résultat que je publie.
Je vous remercie de m'avoir lu.

Hello everyone,
This is a snapshot of the Rosetta Nebula.
I wanted to test a fast lens (F / d4) with 300mm focal length from the Pentacon brand.
I mounted this Lens on the Olympus E ‑ M10 Mark II with the Neodymium Sky & Moon Filter.
I mounted it all on an AltAz Celestron Nexstar SLT mount.
I find that the Contrast boost Filter handles Chromatism better than the Neodymium.
At 5000 ISO, I find that the photos are still very beautiful.
All this shows that we can practice deep sky astrophotography with a small budget. Even with an AltAz mount.

An important thing to know:[b] [/b]
I practice astrophotography from my balcony in a city. My sky is disturbed by the rising heat from the buildings. Thus, by moving, we can do much better than the results that I publish.
Thanks for reading me.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
