trevboyd Posted October 23, 2008 Share Posted October 23, 2008 After my previous attempt at this target the night before, I thought I'd have another go with shorter exposures and lower ISO to keep the core from burnning out.This time, I took 120x10s @ ISO-800. After stacking in DSS, I found the same problem, the core was burnt out. I fiddled with the settings in DSS, and discovered that I had set the "Brightness" setting in "RAW DDP Settings" to "6" (on someone's advice a long time ago). I reset that to "1" and restacked. The result was a much dimmer image, but with the core remaining resolved.A bit of tweaking in PS CS3 produced the result below Interestingly, my subs from last night were much less orange than the night before, with barely a hint on the camera screen (whereas the previous night had produced bright orange previews) - whether an artifact of the reduced exposure, or much less moisture in the air to scatter LP I'm not sure.Hope you like it.(click to enlarge)Trev Link to comment Share on other sites More sharing options...

trevboyd Posted October 24, 2008 Author Share Posted October 24, 2008 Thanks, everyone. After posting it, I compared it with my previous version and I prefer the colour of the original - it's a bit "warmer" than this one, but happy nonetheless.

anthony Posted October 24, 2008 Share Posted October 24, 2008 That is a lovely shot. The core is much better and really makes the shot shineAnthony Link to comment Share on other sites More sharing options...

661-pete Posted October 24, 2008 Share Posted October 24, 2008 Nice work there, plenty of pinpoint stars and good colour (though I'd reduce the blue myself, personally)! I've had a go at most of the brighter globs since I took up imaging, and M15 is one of the most awkward - very dense core and really difficult to get rid of that wretched burn-out! Good effort, yours, shows stars just about all the way in! Link to comment Share on other sites More sharing options...
