North America and Pelican in Ha

First Image in more than three years…. just a screen grab as it’s not good enough for a full size jpeg.

A quick process to re-learn what we’ve forgotten in that time!

7x 600seconds taken at 385mm f/3.6. Dark and flat frames applied.

Calibrated and stacked in Nebulosity. Processed in Photoshop CC 2017.

Been out a few more times since then to try and sort out issues with guiding, mount control and the Robofocuser having stopped working – we’re slowly getting there!

Think now I have a total of 17 subs on this to sort. Then I’ll process again with a bit more care and attention to the finer details and stars. That should (hopefully) be the Ha sorted.

Next year we’ll try and get the SII and OIII to make up a false colour image.
