About this image

The data for this object provided some experimentation using new processing tools. The observing conditions were rather indifferent, with poor seeing and some haze. So I had not a lot of data, and some of it could have been better.

I used Astro Pixel Processor (APP, on a trial licence) for the first time to calibrate the subs. I then used PixInsight to align and integrate the subs and the new Gaia spectral data calibration tool to calibrate the star colours. Finally, I used the new BlurExterminator tool to reduce the sizes of star images. Overall, I'm pleased with the results. I did a parallel process using the PI calibration tools. I've yet to make up my mind if one tool produces better results than the other.
