Markarianin ketju - 12.5.2023 at 00.30 Tervakoski Observation number 116330

Visibility III / V

Kuossari Petri, Riihimäen tähtit. yhdistys

I meant to skip this experiment when Vaonis (the manufacturer of Vespera) asked to photograph the NGC 4438 object on May 12-13 using CovalENS with a field of view of 2.8° x 2.0°. Yes, it was enough and I got 592 pictures on the 12th day and 403 pictures on the 13th. Here is the final result, when the descriptions of 31 people were combined. connection shooting time 49.01 hours and 17675 stacked images.

Hieno kuva.
Tapahtuiko kaikkien osallistujien kuvien yhdistäminenkin jotenkin automaattisesti ?

Kiitos Tapio,

Jokainen osallistuja lähetti oman pinotun TIFF kuvan Vaonikselle, joka yhdisti kuvat.
