Crew 223 Astronomy Report Mar 04 2020
Name: Florian Delpech
MDRS ROBOTIC OBSERVATORY
Robotic Telescope Requested (choose one) MDRS-14
Objects to be Imaged this Evening: Same as yesterday : IC 342 ; NGC 2775; NGC 4449 ; NGC 4254 ; NGC 4125 ; NGC 3338 ; NGC 2683 ; M100 ; NGC 6503; NGC 5248 ; NGC 4038. This is part of the research project aiming at observing about 30 galaxies per week to try to find a supernovae.
Images submitted with this report: A picture of M81.
Problems Encountered: When I wanted to calibrate images with AstroImageJ for M81 and IC1805, I used calibration files (MDRS-WF_mbias, MDRS-WF_mdark, etc.) taken from Skynet on March, 3rd. However, when I launched CCD Data Processor, the following error message appeared : "Fileinfo parameter error. Offset + image size > file length".
To solve the problem, I took calibration files from a previous observation (a week ago) and it worked. So maybe the calibration files from yesterday were too heavy.
Also, I don’t know if it is linked but the image with Halpha filter for both objects was very noised and so unusable.
