Allan the Plumber Posted June 22, 2014 Share Posted June 22, 2014 (edited) Just finished processing M51 using various sessions from June and May and processing in DSS After several processing disaster i decided to read the help files as i needed to get a base point to start from again as i'd changed several of the settings in my quest to get the best out of both my data and DSS so i decided to read up on what settings to use. Found that if you have a laptop/computer with a good processor and especially if using a large field DSLR that using the custom rectangle that you can drizzle Image here explains DSS drizzle explanation by ayounghares, on Flickr Well its worked for me M51 Drizzle DSS by ayounghares, on Flickr original below M51 by ayounghares, on Flickr Edited June 22, 2014 by Allan the Plumber Link to comment Share on other sites More sharing options...
red dwalf Posted June 23, 2014 Share Posted June 23, 2014 good result Allan, if you use the drizzle box, 2x or 3x ( click on screen and drag the box around the target ) it will work with a fairly decent computer, if you try full frame drizzle then it`ll struggle and usually says not enough memory when it has gone half way though stacking the subs, it`s a good feature on canon cameras as you still get lots of area around the target when it`s cropped.

Yeah Rob found that tried to do full image and as you say came up with an error report read on and found as you mentioned the "custom rectangle offering either 2x drizzle or 3 find if processing galaxy etc image very small and when cropped and size increased all that happens is any pixelation increased still not sure if I've got the settings correct on processing but this has brought me the best option yet!

red dwalf Posted June 23, 2014 Share Posted June 23, 2014 i`ll check my settings later, have tried lots of different settings over the last few years in DSS but now i set it to default and compute offsets to find the file with the biggest score, set that as the reference frame then stack automatic and set to kappa sigma clipping, i found that average was coming up with some horrible results, median isn`t bad either, but kappa sigma clipping seems to get rid of any artefacts Link to comment Share on other sites More sharing options...
Guest Philmarriott Posted June 24, 2014 Share Posted June 24, 2014 Looks good Allan. I'm just about ready for some imaging and guiding but still not had the opportunity to get out. Link to comment Share on other sites More sharing options...
