I just reprocessed the IC2087 data that I aquired back in 2016 on the Canon 200mm prime lenses and the Trius M26C OSC CCDs. This is 10-hours worth of 20-minute subs.

This is a 2-frame mosaic using a pair of Canon 200mm prime lenses and SX Trius M26C OSC CCDs. Each frame is 18 x 20-minute subs.

A Composite Leo Trio Using Hyperstar 3 and Hyperstar 4 Data

This is a composite image of the Leo Trio using old HS3 data and very recent HS4 data. Still not showing the tidal tail so plenty more work needs to be done on this one.

Today’s Earth Science Picture of the Day (EPOD)

Posted on March 2, 2022 by Greg Parker

Got today’s EPOD with the DSS2 data I recently processed of the California Nebula (NGC 1499). Thank you Cadan Cummings for the write-up on this one.

Here is a composite image of M78 and the edge of Barnard’s Loop (off to the left). This is old Sky90 data combined with very recent Hyperstar4 data.

What is this?

What do you make of this? 3 x 3-minute subs taken on the Hyperstar last night – the light is moving from bottom left to top right. The first sub was taken at 23:21. The gap between subs is a 1-minute dither delay. If you look at the bottom left there should be just a trace of the light on the previous sub, there isn’t any trace. It’s too slow for any satellite I’ve ever seen, it’s not a plane – so what is it? In 18 years of imaging I’ve never seen anything like it before.

A blast from the past.

The familiar “W” shape of the constellation Cassiopeia is seen in this 5-frame mosaic taken using an unmodified Canon 5D MkII DSLR, and a Canon 200mm prime lens. From the background  you can see that Cassiopeia sits in the Milky Way.

What is going on?

Posted on February 26, 2022 by Greg Parker

Well tonight will be the second clear Moonless night in a row – almost completely unknown! I am imaging M78 with the Hyperstar 4 with good collimation – but I don’t have long before it disappears behind the trees.

Second Light for the Canon 200mm lenses and ASI 2600MC-Pro CMOS cameras.

This is a very quick (and dirty) process of last night’s Gamma Cassiopeia data taken on the 200mm lens rig. It was final setting up time so I managed to get both cameras in portrait mode, aligned both cameras very well to each other, and managed to get perfect collimation on both cameras as well. I finished off with 14 x 10-minute subs which came out pretty much as expected.

First light for the ASI 2600MC-Pro cameras on the Canon 200mm lenses.

Last night was First Light for the new 200mm lens rig. I chose the Gamma Cass region as there’s plenty going on there. Two changes to make, need to rotate the cameras 90 degrees anticlockwise to get them in portrait mode. Also need to slightly tweak the collimation on camera 5 (camera 4 is spot on).

So after God knows how many months of pain and suffering the array is back in business again, just in time to miss the winter goodies – but hey, I’ll get galaxy season. And this new rig will get the whole of the Virgo/Coma supercluster in just 2 frames! Only need the weather now.
