Venus/Jupiter Conjunction 1/7/15

Really happy with how these turned out, although the JPEG compression is immense to get them posted as attachments on the forum. The ~113 megapixel original is a real beauty!

I was in two minds of how to do this event, to image at f/10 native wider field or to make a high megapixel count composite. In the end i opted for the latter, for the challenge but also to give friends/family the ability to zoom in and to be able to keep zooming in while still maintaining the original composition/framing of the event. As such i also wanted to avoid doing insets if possible.

So in the end i imaged and separately processed Venus, Jupiter, Ganymede, Europa, Io and Callisto and used wider field images to get the positions exact. I wanted to minimise the manipulation in photoshop as much as possible.

The seeing was pretty bad, so much of the detail on jupiter was not captured consequently, but nevertheless i was able to catch some of the larger features. I was also able to resolve the moons as discs but with zero detail due to the seeing.

Venus is IR(G)B, Jupiter is IR G B and the moons are all IR G B, with IR being a 610 longpass filter.

All through a edgeHD 925 that i precisely collimated the night before in better seeing conditions.

Any and all feedback is welcome, especially since this is my first composite! I also included some crops although i think IIS will display them the same size as the full composite anyway.

EDIT: I just discovered the "fit image to window" button on the IIS image viewer which solves the displaying problem. wish i knew that earlier!
