A few weeks ago i photographed the milky-way with a 28mm f/1.4 lens and a duo narrowband filter for a complete night and then I stacked the whole session. During the histogram transformation i realised a faint smudge between Cassiopea and the Andromeda Galaxy . My first thought was a halo caused by a street light , but to be sure that this is not somekind of an artefact i took a 135mm f/2 lens aimed the same region for two nights . I managed to collect about 14hours of data and staked them and ....again... the same red and blue smudge .
I stretsched the data so much dat it bekame really noisy , so i decided to continue collecting data for a better signal /noise ratio. In total i collected a bit over 82 hours of narrowbad data that i processed with Pixinsight , the final result is still noisy as i still had to stretsch the data to the absolute limit to get the nebula visible , but i wll continue to collect more data , the goal is to reach 200hours to get a decent picture of this nebula.
i made some research about this area and i was not able to find any mentions of a nebula like this in this area , i followed the tips of
@Nico Carver who discovered the Humingbird nebula not a long time ago, but whith no success.
I will meet a astronomer form The '' Observatory from Paris'' this Week-end to have a talk with him to get sure about what i photographed .
if somebody knows something about this nebula or can tell me where i can find mor informations please let me know.
clear skies everybody
Steve
