NGC 5544 galaxy type (R)SB(rs)0/a (face on galaxy) and NGC 5545 galaxy type SA(s)bc in Bootes.
Together these galaxies form Arp 199 in the Arp “Atlas of Peculiar Galaxies” and are in the class of
“Material Ejected from Nuclei”. Taken over several nights in May and June 2014. Imaged with CCD
Lab’s Q285M (QHY2Pro) camera and a Celestron EdgeHD 9.25 at f10, on a Losmandy G11/Gemini mount. The L
subframes were 12 minutes binned 1x1, while the RGB subframes were 4 minutes binned 2x2 resulting in
the following total exposures L:R:G:B (min) = 492 : 60: 60 : 60. Captured with Nebulosity, calibrated
and sigma combined in Iris with other processing using PixInsight LE and Photoshop CS. North is up.
