Hind’s Variable nebula, Struve’s Lost nebula, Burnham’s nebula, NGC1555 – they’re all the same thing and it is the orange thing in the centre of this image.

A beautiful clear night last night allowed me to grab 41 x 20-minutes to go with the 24 x 20-minute subs taken in 2014.

Got today’s Earth Science Picture of the Day (EPOD) with “Contrasting Star Pair in Auriga”.

Thank you Jim at EPOD for continuing to publish my work.

And here is a 2-frame mosaic combining the IC2087 and SAO76573 frames taken with the Canon 200mm prime lenses and M26C OSC CCDs.

Taken a couple of nights back, this is 10-hour’s worth of 20-minute subs centred on SAO67573 one frame to the right of IC2087 also taken with the Canon 200mm lenses and M26C OSC CCDs.  

At the top/centre there is a very interesting nebula Vdb 27.  The whole region of course is full of dust and dark nebulosity all part of the Taurus giant molecular cloud.

Got today’s Earth Science Picture of the Day (EPOD) with the 200mm lens 2-framer of Castor & Pollux.

Thank you Jim at EPOD for continuing to publish my work.

A rather “quick and dirty” image of the region.  I need to get a lot more, deeper, subs of this region if I can this winter.

Unbelievably last night was the 3rd clear night in a row – Moonless too!!

So – making best use of this gift I managed to grab the final left hand frame on the North America 3-pane mosaic.

This is a 29-hour total exposure time marathon using 20-minute sub-exposures.

2 x Canon 200mm prime lenses with 2 x Trius M26C OSC CCDs.

The first 3-framer with the Canon kit.

Got 6 x 20-minute subs with the Canon 200mm lens which I added to some earlier Sky 90 data.

Got the final bit of data on this one last night.  This is a 2-framer using the Canon 200mm prime lenses and Trius M26C OSC CCDs on top of the Paramount ME.

Main North America frame is 9 hours and 40-minutes total using 20-minute subs.  The right hand frame (with Deneb) is 10 hours and 20-minutes total data time using 20-minute subs.

The ONLY negative thing with the 200mm lenses is the bad ghost flaring from any bright stars in the image.  This makes it an ideal imager for regions like IC2087 where there are hardly any stars (let alone bright ones) to be seen.

I managed to get a further 10 hours to add to the initial 7 hours taken using the Sky 90/M26C array – 20-minute sub-exposures.

I don’t think that the additional 10-hours added much in the way of depth to this image, but it did mean that I didn’t need to use any noise reduction like I had to with the 7-hour image.  This is worth remembering for future “marathon” imaging sessions.  Probably not worth going beyond the “magic” 8-hours per frame.
