M90
Object: M90 (NGC4569, Arp 76)
Spiral Galaxy
 Const.: Virgo
Camera: SXV-H9 Scope: Vixen R200SS Mount: Losmandy Titan
Filter(s): IR block Exposure: 8x8m TeleVue Paracorr
The galaxy M90 in Virgo. A stack of 8 eight minute exposures using an SXV-H9 CCD camera on a Vixen R200SS 8" f/4 Newtonian with a Paracorr. The image was calibrated, defect-corrected and stacked, and a gammalog stretch was performed using AIP4WINV2. This image has been resampled down from its original size of 1392x1040.
 
M90
Object: M90 (NGC4569, Arp 76)
Spiral Galaxy
 Const.: Virgo
Camera: HX916 Scope: Vixen R200SS Mount: Losmandy Titan
Filter(s): IR block Exposure: 53x30s TeleVue Paracorr
The galaxy M90 in Virgo. This image is a stack of 53 thirty second exposures using a Vixen R200SS 8" f/4 Newtonian with a Paracorr and an IR-blocking filter. The image was calibrated, defect corrected, stacked and gradient corrected followed by 15 iterations of Richardson-Lucy deconvolution. Then a simple linear stretch was performed, all using AIP4WIN. This image has been resampled down from its original size of 1286x1012.
