The Taurus Molecular Cloud Around IC2087

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)

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.

M78 and the edge of Barnard’s Loop

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?

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.

MiniWASP major upgrade 17/02/2022

I have just completed a major upgrade to the MiniWASP array, specifically the 2 Canon 200mm f#2.8 prime lenses.

You can now see there are a pair of red cameras on the back instead of the usual black ones. These are ZWO ASI 2600MC-Pro CMOS cameras, 24MPixel!! I have one on the Hyperstar rig and I have been so impressed with it that I swapped out the cameras on the 200mm lenses for the same. Absolutely nothing wrong with the original cameras, but the new cameras give me 3.88 arc seconds per pixel, whereas the original cameras were 6.13 arc seconds per pixel, and consequently the images looked “soft”. The problem was basically me picking the wrong camera for the job!

The other major change on the array is also to do with the 200mm lenses. Can you see the two autofocusing rigs with the toothed belt drive are gone? They have been replaced by the utterly brilliant Astromechanics focusers which talk directly to the lens electronics and are connected to the computer via USB 2.0. Autofocusing is now not only a doddle, but it is also EXTREMELY quick. Another major benefit is virtually zero backlash, which makes it all very easy to run in FocusMax.

I guess we can expect cloud for at least the next year, and to start things off we have gale force winds predicted for tonight.
