The open star cluster NGC 1528, at left, accompanied by the emission nebula NGC 1491, at right, aka the Fossil Footprint Nebula, both in Perseus. The very red star below NGC 1528 is SY Persei. The faint nebula at centre is unidentified – the nebulas Sharpless 2-209 and Sharpless 2-206 are in the area but their positions on the TriAtlas do not coincide with the nebula recorded here. Nor is it marked on any other atlas I was able to check. But the TriAtlas might plot the Sharpless nebulas incorrectly. But photos on-line label this object as Sh2-209. The bright star at bottom right is Lambda Persei. This is a stack of 25 x 5 minute exposures with the Askar APO120 refractor at f/5.6 with its 0.8x Reducer; and the modified Canon R at ISO 800. On the Mach1 mount autoguided with the MGENIII guider. No filter was employed here.
