M27 AT LAST

[p1taylor]

Just got round to doing this, 30x120 seconds, imaged rcx10" and sx h9c, guided lodestar and phd.

Really nice image.

I noticed that there is some slight trailing in the stars, resulting in them having 'eggy' shapes, and I hope you don't mind me trying a little trick in photoshop to reduce it. Here's the result.

Very nice, Peter. Every time I open an M27 thread at the moment, the results just seem to be more and more impressive!

Luke - YOU MUST SHARE THIS TRICK!

Can't remember where I learnt the trick on reducing oval stars, but I copied the following into a file which I keep in a little 'tips' folder in my computer:

1) Duplicate the image as a new layer

2) Set the duplicate layer blending mode to "darken"

3) Then apply Filters -> Other -> offset and adjust the vertical and horizonal offset values until you get round stars.

With Peter's image I just set the offset to 1 pixel to the left. I don't think it works on all images, but I think it worked here.

Sorry, Peter. Didn't want to hijack the thread or detract from your really nice image!

Dont worry Luke, all help and info very welcome, not very good at processing so all advice can only be of use.

Any apology should come from me, Luke. I was the one doing the hijacking (and demanding, etc )

Dont worry Luke, all help and info very welcome...

Thanks for your understanding, Peter.
