Identify asteroids with Aladin and SkyBot

4h40 exposure (L:56x300s)
Acquired on the 28th of February 2019 with Samyang 135mm


Several asteroids in the field of Markarian chain. Samyang 135mm F/2 at F/2.8, QHY163m gain=100

This article depicts a method to identify asteroids on personal photos. This method uses Aladin Desktop software from Strasbourg astronomical Data Center and SkyBot (Sky Body Tracker) from IMCCE (Institut de Mecanique celeste et de calcul des ephemerides) / Paris Observatory. The last part of this article explains how to obtain the orbit as well as the mass of the asteroid using JPL Small-Body Database Browser of NASA.

Quasars in Virgo cluster

4h40 exposure (L:56x300s)
Acquired on the 28th of February 2019 with Samyang 135mm


Setup: Samyang 135mm F/2, AZ-EQ6, QHY163m gain=100, QHYCFW2-M, AstroLink 4 mini, QHY5L2M. Software: APT, Stellarium scope, EQ MOD, PHD2

In previous post was described a method to identify Quasars using Aladin Destop software.
The method is now applied on this wide field image (central part of Virgo galaxy cluster) which has been annotated accordingly in orange.

Identify Quasars with Aladin

4h40 exposure (L:56x300s)

QSO1224+1349 et QSO1222.9+1334 – 2 Quasars located in the north of Markarian chain. Samyang 135mm F/2 at F/2.8, QHY163m gain=100

This article suggests a method to identify Quasars objects on personal photos. This method, very simple, uses Aladin Desktop software from Strasbourg astronomical Data Center.
