Lower's Nebula & Co (from Sh2-254 to Sh2-261)

[gorann]

The moon is up so I went for some fairly bright nebula on Monday night. This is the first time I have imaged Lower's Nebula (Sh2-261), which is named after its discoverers: amateur astronomers Harold Lower and his son Charles, who spotted it in 1939. The wide field of view of the RASA allowed me to also include a conglomerate of Sharpless objects (Sh2-154 to 259) in the upper right corner.

Materials & Methods: Dual RASA8 rig with ASI2600MC and IDAS NBZ filter. 142 x 5 min = about 12 hours. PI and PS including StarXT, BlurXT and NoiseXT.

Cheers, Göran
