California Nebula in Perseus, with 135mm Canon telephoto lens and modified Canon 5D MkII camera, at ISO 1600 for stack of 5 x 2.5 minute exposures at f/3.2 + plus two exposures taken with haze in sky, added in with Lighten mode to provide glows around stars. IC 348 faint reflection nebulosity around Omicron Persei at bottom right just showing up.
NGC 1514,Taken Oct. 8, 2007 with 5-inch Astro-Physics apo refractor at f/6 with Canon 20Da camera at ISO 400 for single 15 minute exposure. Guided with Meade DSI/66mm guidescope and PHDGuide sofware. Haze and cloud prevented more exposures.
The open clusters NGC 1528 (top and prominent) and NGC 1528 (lower left and sparse) in Perseus, along with dim and sparse NGC 1513 at lower right. The small HII region NGC 1491 is at upper right near the frame edge. All are in Perseus. This is a stack of 4 x 6 minute exposures with the Canon 6D at ISO 800 and through the TMB 92mm refractor at f/4.5 on the AZ-EQ5 mount for testing. Shot Nov 4, 2015 from home on a cool crisp night with lots of airglow and an odd aurora to the south. Slight frost was forming on the lens at the end, adding some star glows. Star spikes added with Astronomy Tools Actions.
