Messier 56 (NGC 6779)

Globular Cluster in Lyra      RA 19h 16m 06s  Dec +30° 11m 00s


Mike Lancaster captured this image of M56 on the 11th August 2023. The image comprises 100 x 6s exposures taken using an Altair Hypercam 26C at 300 gain (plus darks, flats and flat darks), through an Orion Optics UK AG12 Astrograph mounted on an EQ8 mount. A 0.95x Wynne Corrector and Optolong L-Pro filter were also employed. No guiding was used on account of the short exposures. Images were acquired using SharpCap, and the processing was entirely performed in PixInsight.   Image © Mike Lancaster.




This image of M56 was captured by Mike Lancaster on the 22nd July 2021. It is comprised of a stack 4x3 minute exposures taken with a Mallincam Universe camera attached to a 10-inch Meade ACF SCT on an EQ-8 mount. A 0.5x Mallincam focal reducer was also used. The camera was set to a gain of 16dB, a gamma of -20, a contrast of 0, noise reduction on, and full resolution. No guiding, flats or dark frames were used. Stacking and processing was done in Nebulosity 3.3 and Photoshop Elements 2020.   Image © Mike Lancaster.
