Peresus in a stack of 5 x 4 minute exposures with the Canon 5D MkII at ISO 800 and 50mm Sigma lens at f/3.2. Plus two exposures taken thru the Kenko Softon filter for the star glows. Takes in the nebulosity in this part of the Milky Way including IC 1805 (top left) and several prominent star clusters: NGC 752 (right), M34 (centre) and NGC 1528 (left), as well as the Perseus OB Association (left of centre) and variable star Algol (centre). Taken from home Sept, 29, 2013.
The Milky Way through the Perseus to Auriga area, populated by clusters and nebulas of the next spiral arm out from ours, in the Perseus Arm. The Double Cluster is at right, with the Heart and Soul Nebulas above it, while the Auriga clusters and nebulas are at left. At bottom is the California Nebula and Messier 34 cluster. The Perseus OB Association of hot blue stars is at centre. Capella is the bright star at upper left. The Taurus Dark Clouds are at lower left. This is a stack of 8 x 3-minute exposures with the 35mm Canon lens at f/2.8 and Canon EOS Ra at ISO 800. 4 shots were through the NISI Natural Night light pollution reduction filter and 4 were through the Hoya Red Enhancer filter, taken as part of testing. An additional exposure through the Kenko Softon filter adds the star glows. Taken from home on a very clear night, December 29, 2019 on the iOptron SkyGuider Pro.
The region in Serpens and Ophiuchus containing the Serpens-Ophiuchus (S-O) Double Cluster, here at top left, and the large binocular cluster IC 4655 above the cyan-tinted star Cebalrai, here at right. The S-O pair is made of IC 4756 (left) and NGC 6633 (right). Included near centre is the V-shaped asterism known as Taurus Poniatowski or the “Little Bull,” a group that resembles the Hyades in Taurus. The group was named for the King of Poland, Stanislaus Poniatowski in 1777 by Marcin Poczobutt. The constellation pattern was never accepted but the asterism, now in Ophiuchus, is a fine one for binoculars. This is a stack of 3 x 3-minute exposures with the 85mm Rokinon lens at f/2.8 and Canon 6D at ISO 800, plus an additional 3 min exposure through the Kenko Softon filter to add the star glows. Taken from home July 29, 2019. All tracked on the MSM SiFo Tracker from China as part of testing. At this focal length the little MSM tracker proved problematic as many frames were trailed. It was not reliable enough in its tracking to yield pinpoint stars in most shots.
