SeeStars are amazing machines. SeeStars in equatorial mode are even more amazing. Like that, you can get images that would have made NASA proud just a few decades ago. But getting the SeeStar into the right position takes some doing.

Safely leaning the heavy machines back, setting them accurately, and putting the SeeStar in the correct start position takes the right gear. There’s a lot of gear out there that will do some of these, but not much that does it all.

We wrote a blog to show how it’s done using parts you won’t want to return.

Guide scope or finderscope? Why can't we have both?

Ever tried to convert a finderscope to a guide scope? Worse, have you ever tried to convert a guide scope to a finderscope? (Hint, you'll need an angle grinder)

We've been playing with a ToupTek scope that genuinely does both. Here we have the same scope as a finderscope with a mirror diagonal, with a prism diagonal, with just a straight through eyepiece, and finally, with a guide camera.

All this, and a nice stable rack and pinion focuser.

Blue and green should never be seen - without a colour (black) in between?

This is the new Sky-Watcher Evostar 72EDX with flattener sitting on a Pegasus NYX101. We've got high hopes for this little scope - its predecessor was a standout in its class. This one has a rack and pinion focuser plus some extra bling, but the optics are identical. And the NYX is strong enough for about eight of these!

When I see this, I can only see a dentist's chair. Or maybe a rocket launcher.

It's a Sky-Watcher Fusion 300DXi Kit with Equatorial Wedge. In AZ mode it'll lift 30kg, in EQ mode that drops to 25kg.

It's big.

But the other thing you need to know is that we think there is ONE in Australia.

It's been a while, but we've got a new video.

Astroasis filter wheels, featuring the 7x36 but also the 7x2" are innovative and impressive. Bill unboxed one and went through its features.

Oh, that new scope smell!

We were disappointed to see that Sky-Watcher had discontinued their Evostar 72ED. We thought it was an under-appreciated scope, and used it for astrophotography courses with a flattener and DSLR.

Well, hooray! This is the new version , called the Sky-Watcher 72EDX. The glass is the same, 420mm FL and 72 aperture. Upgraded to a dual speed R&P, nice smooth rotator, movable dovetail (the old one was quite inflexible).

I was just waxing lyrical bout the scope for tonight’s newsletter when one turned up at the front door!

Sneak peek.

A bit more arachnophobe warning here!

The whole focus-stacked macrophotography image is nearly all of the spider. To be honest, it's a bit terrifying, so we decided to just show the results for one of the spider's knees.

The test was to find the effect of adding a dome-shaped diffuser (https://siderealtrading.com.au/product/wemacro-dome-softbox-light-diffuser/) as against two simple undiffused flashes. The first image is the undiffused light. You can see the deep shadows and harsh highlights the flashes produce. These highlights are fully blown out, meaning you can't reprocess the image to save the information.

The second image is with the diffuser, so the light gets deeper into the knee without getting too shadowed. We were also able to process the image a little because the highlights were less intrusive.

To get this softer light, we previously had to use paper baffles, and reflect off scrunched up aluminium foil. It was a major PITA.

Given time, I'll write a bit more detail for this week's newsletter.

We’ve been testing a soft light dome diffuser. If you’re of an arachnophobic disposition, you might like to look away soon, but we’ll get the hard light first.
