M71 Globular Star Cluster
M27 Dumbbell Nebula

by Gabriel Perez

This image is of the M71 Globular Star Cluster in the constellation Sagitta. This globular star cluster is about 12,000 lightyears away from Earth and about 27 lightyears in diameter. 

The image is comprised of 58 minutes worth of LRGB data. The imaging telescope was a William Optics Megrez 90 with no coma corrector. The imaging camera used was an ATIK 314L+, which was autoguided with an ATIK Titan. Everything was mounted on an Avalon M-Uno. Post-processing was done in PixInsight. 

M27 Dumbbell Nebula
by Gabriel Perez

The M27 Dumbbell Nebula is a planetary nebula located around 1,360 lightyears away from Earth and is approximately 2.88 lightyears in diameter. This object was the first planetary nebula discovered by Charles Messier in 1764

Taken using the ATIK 314L+ and guided with the ATIK Titan. Imaging consisted of 17 minutes Hydrogen-Alpha, 17 minutes Oxygen-III and 14 minutes UHC-S with poor night sky conditions. The Rock face was illuminated, the La Linea Fair was active and our famous Levant (hence UHC-S and no Sulphur-II). Post-processed in PixInsight using bias, darks and flats. The telescope used was the William Optics Megrez 90, all mounted on the Avalon M-Uno.


The images were taken on the 28/01/15 using TAK106 on an M-UNO mount with only polar alignment and no tracking. The camera used was the QSI 660 and LRGB Astronomik filters, a series of 4 images of 30sec through each filter. The images were processed using PixInsight.
