alan4908 Posted April 10, 2018 Share Posted April 10, 2018 An LRGB image of a galaxy grouping in Leo, the image represents just under 12 hours integration time and was taken with my Esprit 150. I quite like the shot, since it illustrates the wide variety of galaxy types that are out there. I've included an annotated version which shows that some very distant galaxies are also present in the image. It also highlights the position of the somewhat featureless nebula NGC3193. Alan LIGHTS: L: 17, R:17, G:18, B:18 x 600s, DARKS:20, BIAS:100, FLATS:40 all at -20C. Link to comment Share on other sites More sharing options...
adyj1 Posted April 10, 2018 Share Posted April 10, 2018 Very nice. A real "who's who" of galaxy types! Ady Link to comment Share on other sites More sharing options...

Thanks. Hi John - the annotated image was generated with Pixinsight - it gives various options that allows you to customize the output eg font size, stars on/off etc, so that you can tune it to generate a non-cluttered result.

Jkulin Posted April 10, 2018 Share Posted April 10, 2018 Thanks Alan, I use PI but had never noticed that as it would prove quite useful, can you point me to where those settings are? Hope you don't mind? NB Ignore me just found it under Annotation, just need to have a play with it now. Link to comment Share on other sites More sharing options...

Hope you don't mind? Sure - firstly, open an image that you want to annotate. You first need to plate solve the image so go to SCRIPT->Image Analysis->Image Solver. Use the search option to get the RA/DEC coordinate of your object your plate solving. Select the solved image and then go SCRIPT->Render->Annotateimage - when you do this - various options will appear that allow you to customize your output.

Jkulin Posted April 10, 2018 Share Posted April 10, 2018 @alan4908 Thanks so much Alan, just tried that on a few images and it works brilliantly, what makes it so good is that against the images I capture I can save that as the master file image for lookups of the stars etc. I would never have seen that option if it hadn't been for you, so a big thanks.
