Hi everyone ! I have created this new blog to share more easily my comments about the world of planetary astronomy. Even if I'm already an experienced observer, there are always things to learn and products or techniques to test and I hope to share this here. I will also post informations about the events I'm attending regularly and other stuff. Planetary astronomy today is becoming again a dynamical domain of observation so let's improve and share our passion !
Let’s start first by what will not change in comparison with any other camera: how you are going to choose the time exposure, the gain; the length of the video… This must be set as usual, following the object, the conditions, the filter used, etc. Only the very high sensitivity…
Despite its very high sensitivity, the IMX462 is less suited than a mono sensor to use with red+IR filters or shorter IR longpass filters (685/700 nm). Among the comparisons between colour and b&w sensors I have been carrying out, one brought a surprise when I saw the results. On September…
I have dedicated much of my Jupiter’s observing time in 2021 to test this promising sensor for IR planetary imaging. This is the first article of my investigations (two more will come)! Typical set of Jupiter IR images taken with the ASI462MC camera (the telescope is a 305 mm Skywatcher…
Looking at the spectrum of Venus allows us to understand the behaviour of the available filters! A few images After having discussed the spectrum of Venus, we can now have a closer look at the filters that the amateur can use. We are only going to talk about those who…
By using the same approach as for the Full spectrum of Uranus commented, it is possible to understand many things about the behavior of the filters used to image the planet. First article of a serie dedicated to Venus imaging. Perceived as uniformy white when viewed through a telescope, Venus…
To image details on Uranus, amateurs are using red and/or infrared filters. Spectroscopy is a nice tool to describle the actual effects of those filters…
Spectroscopy is a powerful technique to analyse and understand the celestial objects. It provides us with information about their chemical composition, the quantity of emitted light… Here is a low resolution spectrum of Uranus, commented for pedagogy.
No need of an equatorial plateform anymore!
There are many IR-pass filters on the market. Here is a short guide to help you pick one… or several of them!
When it comes to reveal details on planetary disks, we mainly deal with image processing technics. But in this article I will describe how interesting can be another technic that it is the animation of still images to make planetary globles rotate. I have re-discovered this (by the way not…
