Lagoon and Trifid nebulae - galactic disc widefield


Recommended Posts

This is a quick processing of the galactic disc. I used a canon 100D Baader modified, a canon 200mm lens at 2.8 and a ioptron skyguider in a rural location in northern Spain.

Hope you like it.

Good stuff.

Using the lens at 2.8 is pretty brave. I'm not dead sure focus is fully nailed. It helps to focus on a star placed at the intersection of the 1/3 lines. (A thing I learned from Psychobilly.) After that, fine focus is really tricky and worth spending a long time on. The field is great and I do like the image.

Thank you for your kind comments. You are right Olly, I don't think focus is spot on. I also use a star in that area but with widefield lenses I struggle to tell when the focus is 200% right. I am used to Bhatinov masks where things are much easier.

By the way, anyone knows where I can find a good tutorial on using star masks? I always struggle with targets like this. In this image, the Lagoon and Trifid benefitted from a little sharpening and a high pass filter but I wanted to keep the stars controlled.
