Hydrogen-α
Object: NGC7635	The Bubble Nebula Region	Const.: Cassiopeia/Cepheus
Camera: SXV-H9	Scope: Tele Vue NP-101 @ f/4.3	Mount: Losmandy Titan
Filter(s): Hα	Exposure: 9x8m	TeleVue 0.8x Focal Reducer
NGC7635 (the Bubble Nebula) NGC7538 and SH2-159 on Cassiopeia-Cepheus border. This image is a stack of 9 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 using its 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.

 

Hydrogen-α
Object: NGC7635	The Bubble Nebula - Emission Nebula	Const.: Cassiopeia
Camera: SXV-H9	Scope: Tele Vue NP101 @ f/4.3	Mount: Losmandy Titan
Filter(s): Hα	Exposure: 10x8m	Taken during a full moon
NGC7635 (the Bubble Nebula) and the open cluster M52 in Cassiopeia. The open cluster Czernik 43 is also visible, just below M52 on the left edge. This image is a stack of 10 eight minute exposures shot through a Hydrogen-alpha filter one day before a full moon. The exposures were acquired using an SXV-H9 CCD camera on a Tele Vue NP-101 4" f/5.4 refractor using its 0.8x focal reducer. The exposures were calibrated, defect-corrected and stacked using AIP4WIN, and a Wavelet Sharpening filter was applied. This image has been resampled down from its original size of 1392x1040.
