The Monkey Head nebula – just a single hour using the Hyperstar III systemPosted by Greg Parker in Hyperstar and SXVF-M25C
Taken on the evening of Friday 13th January 2012 (living up to its reputation just about EVERYTHING went wrong this night) we have the NGC2174 region in Gemini known as the Monkey Head nebula. I have North down in this image so that the Monkey’s Head is clearer to see. What is amazing about this image is that it is just one hour’s worth of exposure time (6 x 10-minute subs) using the ultra-fast Hyperstar III system at f#2. There was also an intrusive Moon playing havoc. This turned out so well under adverse conditions that I feel I must do it justice by imaging it again on a Moonless night with maybe 5-minute subs just to get the total number of subs up.
Towards top left of this image you can see the elongated trail of asteroid 12 Victoria. Around 50 subs at 3-minutes per sub with the Hyperstar III – bright Moon and a lot of thin high cloud but the asteroid still shone through. The bright star should be red. One thing to note, the images were dithered so that I could remove all the hot pixels with SDMask stacking – except if you use SDMask staking then it treats the asteroid trail as outliers and you lose your asteroid
The December 21st 2011 pinhole camera image is today’s Earth Science Picture of the Day. Thank you Jim for continuing to publish my work

A 3-frame Hyperstar III mosaic of the M87 region in B&WPosted by Greg Parker in Hyperstar and SXVF-M25C
Another fine Horsehead image from another PAIG lady – this time it’s the return of Anna Morris (who shared her amazing NGC7000 region mega-mosaic with us a few weeks ago). Very nicely processed image Anna – and what can I say to the PAIG guys other than – THE GIRLS ARE CREAMING YOU LADS Anna provided the following details for her image: Horsehead Nebula imaged 18 Dec 2011 into morning of 19 Dec 2011, scope: Orion EON80ED, camera: Atik 314L+ Ha: 4x1800s, 6x600s, SII, OIII: 3x1800s (bin1) each, SII, OIII: 6x600s (bin2) each, RGB: 4x600s (bin2) each. Total: 500 min (8hrs, 20 min) What can I say other than the image reflects the amount of data taken and confirms my own findings that for First Class images you need in excess of 8-hours total imaging time if at all possible. There is no substitute for time spent on an object.
