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. 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. Since then, C/2023 P1 Nishimura has increased in brightness and its path across the inner Solar System determined. TheSky can import the updated orbital elements data sets (the data that. I take 6 x 10 minutes exposure with my 8" f/d7 Newtonian on a HEQ5 + Eqmod. The comet was discovered only ten days ago by Hideo Nishimura during 30-second exposures with a standard digital camera. The drift rate Arcsec/hour computed by CdC was 12 in RA and -37 in Dec. The developer, ESCAPE VELOCITY LIMITED, has not provided details about its privacy practices and handling of data to Apple. The target is C/2014E2 Jacques on October 22 between 19h56UT and 20h56UT. If it is important for you keep old elements data because you frequently work with older date, the solution is to update the elements from the menu Setup / Solar system that keep the exact same capabilty as today.Finally I find some time, telescope access, and clear night to test the comet drift. ![]() Light takes 43 minutes and 37.3162 seconds to travel from Comet 45P/Honda-Mrkos-Pajdusakova and arrive to us. The beta version that will be available since next Monday will include this delete action when you update the comet and asteroid elements from the main menu Update entry. The distance of Comet 45P/Honda-Mrkos-Pajdusakova from Earth is currently 784,651,653 kilometers, equivalent to 5.245072 Astronomical Units. You can select every file downloaded since May and delete them, or use the quick delete option to remove all. The solution is to delete the old comet elements from the menu Setup / Solar system / Comet / Data maintenance. This meant CdC continue to use the wrong elements even if you update the comet file now. So if you downloaded this wrong file it is still in use because it's date in September is closer to now than the right file that is for May. Observers on Earth can see Comet Nishimura with a telescope or binoculars, but may also. But where is the file that holds the element data I checked C:UsersDellAppDataLocalskychartMPC and found the COMET data file for today but no sign of the added comet. 12, 2023, and then will carry on toward the Sun. Created element of C/2014 UN271 through Solar System menu. It will make its closest pass by Earth on Sept. Comet Nishimura is green in color with a long, white tail. The problem is CdC keep old elements in the database for the case you select a earlier date for the chart. A new comet is visible in the predawn skies as it passes close to Earth on its journey around the Sun. ![]() It was identified this file give a wrong orbit at least for C/2018 W2. But worst, a wrong file was briefly available in September. The currently available file show a computation date of May 14. Chart the stars and planets visible to the unaided eye from any location, at any time of day or night, on any date between the years 1600 to 2400 by entering your location, either via zip code, city, or latitude/longitude. We see with the missing elements for C/2019 Q4 that the MPC as some issue at the moment and the comet file is not updated regularly. Valid domains for entities can be from any of Planet, PlanetaryMoon, MinorPlanet, Comet, Exoplanet, Star, StarCluster, Nebula, Galaxy. The interactive sky chart offers a lot in the way of customizing what you want to see.
