PGC 35345 (Arp 296)

NGC 3690A (right center) spiral galaxy type, SBm? Pec, NGC 3690B (left center) galaxy type, IBm pec
and IC 694 (above and to the right of NGC 3690) in Ursa Major. Together these three galaxies form
Arp 299. PGC 35345 (upper left of NGC 3690) is of type SB(r)ab HII and SDSS J112850.64+583336.7 is
the connected galaxy to the filament (below PGC 35345) and is of type S: pec sp. These two make up
Arp 296 in the class of Double Galaxies with Long Filaments. Taken April 23, 24, 25, 26, 29 and
April 30, 2019. Imaged with Starlight Xpressí SX-825 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 5 minutes binned 2x2 resulting in the following total exposures L:R:G:B (min) = 504 : 80: 80:
80. This image is displayed at 0.57 arc-seconds per pixel. Captured with Nebulosity, calibrated and
sigma combined in Iris with other processing using PixInsight LE and Photoshop CS. North is up.
