To learn more about Cartes du Ciel visit the official website.Īnd to make it easier for you to get the most extensive telescope and amateur astronomy related news, articles and reviews that are only available in the magazine pages of Astronomy Technology Today, we are offering a 1 year subscription for only $6! Or, for an even better deal, we are offering 2 years for only $9. – Allows the ability to lock at the position set from the menu View/Position. – Option to not filter the bright nebula by magnitude, only by size. – Option to show only the celestial equator line. – Separate label setting for Asteroid and Comet. – Added update menu for Delta T and Jupiter GRS. – Allowa per chart observatory horizon profile. – New button to Park/Unpark the ASCOM telescope. – Set observatory coordinates from the telescope GPS, this set a “Telescope” observatory name and does not override other settings. Calendar rise/set are always given to the astronomical horizon. This can be disabled in Setup/Observatory. – Shows the object rise and set time relative to the local horizon if a horizon file is loaded. – New mosaic tool to prepare mosaics for image capture. – Allows the use of the HNSKY star catalog in the “290” format. – Support for the new GAIA DR2 star catalog. It is now possible to use a telescope connected to a remote ASCOM Windows computer from Skychart running on Linux or macOS. – Add direct connection to Alpaca telescope. Use larger image for big buttons and high-resolution screen. – New icon for the buttons, better suited for night vision filters. – New default interface with two button bar. In the latest version 4.2 of Cartes du Ciel offers the following changes: A large number of parameters provide the ability to choose specifically or automatically which catalogs to use, the color and the dimension of stars and nebulae, the representation of planets, the display of labels and coordinate grids, the superposition of pictures, the condition of visibility and more. The main functionality in the program is the ability to prepare different sky maps for a specific observation session. The position of planets, asteroids and comets are also shown. It provides the ability to draw sky charts, making use of the data in many catalogs of stars and nebulae. The small residual comet drift is most probably because of field rotation around the guide star because of the quick polar alignment and poor guide scope parallelism.Cartes du Ciel is a free open source planetarium software to use on Windows, macOS or Linux platform. To show the result I make an animated GIF of the six RAW images just stretched and cropped, without any alignment: But I wanted to be sure to show the comet movement so I keep at 0.95"/pixel. The seeing was unfortunately bad and I have normally imaged with a shorter focal length on this night. The guide scope is a Skywatcher achro 80/400, the guide camera a DMK21.Īll running on Win7, I not wanted to mix Linux problem at this time. The main camera is an Atik 314L+ drived by APT. I take 6 x 10 minutes exposure with my 8" f/d7 Newtonian on a HEQ5 + Eqmod. The drift rate Arcsec/hour computed by CdC was 12 in RA and -37 in Dec. The target is C/2014E2 Jacques on October 22 between 19h56UT and 20h56UT. Finally I find some time, telescope access, and clear night to test the comet drift.
