Description

Hello everyone, last weekend a storm swept the area and the deck of my observatory leaving my equipment outdoors in one of the worst storms in more than 100 years, I thought it was a good time to review some interesting old data, In this case the growing nebula, from which I captured a lot of data including RGB and I could not use it because I did not know how to perform the process correctly and the blue ones (OIII) gave me many problems.

This time I have made new stacks, practically the same in Ha (10h), however I have reduced the OIII time from 11h 40min to 8h 45min and selected the best sub. In addition and included my RGB data and I performed a luminance with Ha + OIII. The image seems to me much better in general although I have lost a little bit of detail in the oxygen with respect to the previous image (https://www.astrobin.com/g6pgwb/D/?nc=user), you cannot have everything. ..

For a season I will dedicate myself to rebuild the obsevatory.

Greetings to all and see you soon, I hope ....
