Hi,

Long time no see.

I forget whether my current one is GPS 1 or 2 but September a year ago I
tried a test comparing astrotracer and the new mode 3 where they
actually measure the movement on the sensor, and Mode 3 works a lot
better, if you have it on your camera.

All of my astrotracer stuff is up at:

You can see that the GPS based stuff actually works pretty well.

I have one. I've used the GPS function with my K-3, but I haven't really
used the astro tracer function.

I have a Sky-Watcher Star Adventurer 2i that works quite well for
tracking stars/moon/sun with a telephoto lens on a DSLR.

I used it to photograph the Annular Eclipse in October 2023 out in New
Mexico. I made a little movie in Photoshop:

The motorized equatorial mount works with my K10D, K20D, K-3 and K-1

I had my K20D converted to IR.

I went down to Texas for the 2024 Eclipse. I set the Sky-Watcher up to
start tracking the sun before the eclipse.

When heavy clouds rolled in just as the eclipse was beginning, I
switched to the converted K20D and could still photograph the eclipse
through the clouds.

I have solar filters for my 80-200 f/2.8 and for my 300 f/2.8

Hi!

Welcome back! Happy star photography!

You’d better be quick as 3I/Atlas will be at its closest to Planet Earth tomorrow, dangerously near to the winter solstice, and one of two things will happen - either a child will be born of a virgin in a stable and be declared the new Dalai Lama, or the War of the Worlds will begin and we will all be exterminated.

So, as I say, welcome back.
