Deep-Sky Image of the Week – Astrophotographer Anna Morris

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.

Hyperstar III 2-framer B&W galaxy scene

  A Hyperstar III 2-framer of the Markarian Chain/M87 region in the Virgo galaxy cluster.

M100 galaxy North West of the Markarian Chain

This is a single frame Hyperstar III image of the M100 region taken in April 2010.  Again presented in colour and in B&W so you can see the numerous “faint fuzzies” in the background.

Second frame of the Virgo/Coma galaxies mega-mosaic

The second of 7 frames of data processed in colour and B&W.  This one is centred on M87.

Serendipitous data archive – the Virgo/Coma galaxies

Frame 1 of 7 taken with the Hyperstar III processed and ready to be made into a mega-mosaic  of the Virgo/Coma galaxy region.  Over 16 hours of Hyperstar III data taken between 7th April 2010 and 17th April 2010 found in the archive and now being processed.  Fairly straightforward processing each individual frame – but stitching all the frames seamlessly together is going to be a major challenge 🙂  Get your star map out to see how much ground I’ll cover with this one.  It goes from M100 furthest  North to M98 furthest West down to M60 furthest South/East.  WOWSER – this is going to be a biggy!!!!

Galaxy central

I just found some old unprocessed Hyperstar III data from 17th April 2010 and got on and processed it this afternoon 🙂  This is the Markarian Chain of galaxies in Virgo, and everything that is not obviously a star is a galaxy.  Put in B&W again so you can have fun counting all the “faint fuzzies” in this one – I can tell you there are a lot!  Went pretty deep here as it was the Hyperstar III at f#2 and there are 34 sub-exposures using 5-minute exposures per sub – just 10-minutes short of 3-hours of total exposure time on this one.  Also found on the HDD another 7 Hyperstar III frames making up a mega-mosaic of this whole galaxy-rich region – all unprocessed data.  I think you can guess what I’ll be working on for the next week or so 🙂 🙂

Phecda & M109 Hyperstar image in negative B&W

Negative B&W images of deep-sky scenes are great for picking up all those background “faint fuzzies”.

First Hyperstar III image of 2012

As mentioned below, last night I focus trained and collimated the rebuilt Hyperstar III system on the C11.  This image is the result of 10 x 5-minute subs taken with a bright Moon playing havoc as well as thin high wall-to-wall cloud.  To say I am extremely pleased with this image is a massive understatement.  Pin sharp (and round!) stars right across the M25C chip – it’s looking better than ever 🙂  These subs were also dithered, so no hot pixels to be seen!  Also – took my very first set of flats for the Hyperstar III this morning (and bias frames) so all the subs were flat and bias calibrated which made the processing of this data a doddle.  I am going to have great fun getting back into Hyperstar imaging and my latest thoughts are to add the fine faint detail to the wide field mini-WASP data using the Hyperstar data.  I think this combination is due to create some pretty amazing deep-sky images 🙂 🙂

Hyperstar imaging once again!

There is a bright Moon overhead and tons of thin high cloud – no good for imaging but perfect for getting the Hyperstar tuned up again 🙂  Managed to focus train and collimate the Hyperstar to better than ever before in under an hour – now that is a record!  Perfect stars corner to corner, superb collimation, and I’m now doing a spot of ultra-fast f#2 imaging (with dither) just to fine check the system and give the stars a good analysis tomorrow.  The image won’t be top rate (due to the Moon) but at least I’ll be all ready for the next clear Moonless night.  Hyperstar rools.  And I now have a sticky note on the rig to the effect that the Hyperstar does not come off again – ever 🙂

Double Cluster sans spikes

A reprocess taking the ugly spikes off the Double Cluster itself!
