Description

This is my big project I have been working on for the past few months. This is Rho Ophiuchi and Blue Horsehead.

This is a 20 panel mosaic. Final image is 937 megapixels (this is huge!!)

Camera : QHY600 with Readout mode 0 and Gain set to 26

Telescope: Takahashi FSQ-106EDX4

Mount: AP Mach1GTO

Each Panel is made up of the following:

(20) Lum @ 180secs - 1x1

(10) R @ 300secs - 1x1

(10) G @ 300secs - 1x1

(10) B @ 300secs - 1x1

I had to also shoot extra panels to correct for some flares from Antares. Total integration time used is 73.2 hours. I shot over a hundred hours but not all the data got used if it was not good enough.

This was shot from the remote observatory in Marathon, TX at the Marathon Motel and RV Park. The Sky Park the owner has built is amazing and the skies there are just phenomenal!! If you are in the area you should definitely check this place out.... or just make a trip there specifically for this!!
