Rho Ophiuchi mosaic from SPSP

this is my first attempt at pulling together my widefield work from SPSP. there are just a couple of spots that may need a tweak if they are mosaic issues, but i'm reluctant to start hacking away with masks in photoshop until i'm certain they're not supposed to be there:

click again for larger size (1500 px). the full size image on my PC is 8500 pixels wide.. Photoshop has been slow today

with five+ hours on four panels, this is now the longest total exposure i've put into a final image.. 21.4 hours and that's after throwing away a few more hours shot at lower altitudes. not bad for a portable setup.. but mainly thanks to (almost) four clear nights in a row!

happy to hear if you think you can spot the joins in the mosaic. taken at the same time at SPSP i also have a mosaic with QHY9 and scope of the central region which i haven't looked at yet..

oh.. and my Drupal website has decided to throw in some PHP errors as well (but you can still get the image)..
