Hydrogen-α
Object: Simeis 147 (Sh2-240)	Supernova Remnant	Const.: Taurus
Camera: STL11000M	Scope: Tele Vue NP101is	Mount: Losmandy Titan
Filter(s): Hα	Exposure: 8x8m	blank
Simeis 147 (Sharpless 2-240) in Taurus. This image is a stack of 8 eight minute exposures shot through a Hydrogen-alpha filter. The images were acquired using an STL11000M CCD camera on a Tele Vue NP101is. The exposures were calibrated, defect-corrected and stacked using AIP4WIN V2. This image has been resampled down from its original size of 2672x4008.

 

Hydrogen-α
Object: Simeis 147 (Sh2-240)	Supernova Remnant	Const.: Taurus
Camera: SXV-H9	Scope: Tele Vue NP101 w/ 0.8x FR	Mount: Losmandy Titan
Filter(s): Hα	Exposure: 7x8m	TeleVue 0.8x Focal Reducer
Simeis 147 (Sharpless 2-240) in Taurus. This image is a stack of 7 eight minute exposures shot through a Hydrogen-alpha filter. The exposures were acquired using an SXV-H9 CCD camera on a Tele Vue NP-101 4" f/5.4 refractor equipped with a 0.8x focal reducer. The exposures were calibrated, defect-corrected and stacked using AIP4WIN. This image has been resampled down from its original size of 1392x1040. This is just a tiny piece of this very large object which spans over 4 degrees. There is a MegaStar finder chart below, with a yellow rectangle showing the part of the nebula covered by this image (The image above is rotated 90 degrees clockwise, so north is to the right). Clicking on the chart will show a larger chart of the whole nebula. This chart was created using MegaStar V5.
