Description

Hi all!
This is my first attempt at this nebula in HOO bicolor palette... There is a very small component of RGB for stars only.
The main image datas where been acquired with my portable setup with the Takahashi Epsilon 210 and QSI 683 Camera. The telescope was not perfectly collimated after my recent issues and so I decided to acquire hal frames in one position and the other half with 90° offset for better rejection of odd shaped stars. I've also managed to include several other frames acquired in the past with two other optics and CCDs. For that I've used some Ha-OIII datas with an old Mirage STF Mak 180mm at f7 and my back illuminated FLI PL4710 and other at increased resolution with my old OS ProRC 360. Filters used where been always the same Astrodon 5nm HII-OIII. RGB where just 5 min per channel. The base image has been enlarged just a little while the others shrinked down to cover and match the frame.

Thanks for stopping!
