Agreed. One of the most astonishing pictures that I have ever seen. It was the background for my desktop for years. It has only got better with JWST.

I didn't realise that you did a podcast! Thanks for this.

Nice mosaic. I will be interested in seeing the final product. Is this one night's work?

See my inadequate description of the starless version of this photo. In this one we we the stars and there are lots of them because we are on the edge of the Milky Way

Here's the Tarantula nebula...with stars this time. #astronomy #astrophotography #seestar #tarantulanebula

Love it and the information that goes with it. Can I ask: is this one photo or a mosaic? Cheers

The centre of the Tarantula Nebula is very bright and it looks like it has a number of clouds exploding from the centre bright region.

This is a starless view of the Tarantula nebula, found around 160,000 light years from earth. If you want more information the Wikipedia entry is illuminating. #astrophotography #astronomy #seestar

The picture shows two images taken with the Seestar S50 telescope. The one on the left shows the central star surrounded by a dark pink half halo. On the right of it is a dark are then a brigher area which looks like a horn (upside down). It is a stack of 12 photos taken over two minutes. 
The second photo is the same nebula but it is a stack of 1200 images taken over 10 hours. It shows much more detail in the halo - swirling clouds of dust, still mainly pink but with reds, greys and whites mixed through it. The 'horn on the right now also has much more detail and it now looks like a scary face with half a mouth and one eye!

The difference between taking an image of the Orion Nebula (M 42) for two minutes and taking if for ten hours! Both done with the Seestar S50 and are taken eighteen months apart! #seestar #astronomy #astrophotography #orionnebula #M42

This is print of a female superb wren by Rachel Hollis. It is a small bird but fills up this screen. It is predominately plain brown in colour, with a white breast and reddish bill and lores. Her long tail points up at almost 90 degrees to her body.

Just recieved some greeting cards from @rachelhollisart.bsky.social in the post. Thanks so much Rachel.
This female superb wren was the first one I saw and it looks stunning. As a bird lover, I can highly recommend her work.

I have just done a Southern Hemisphere version of this galaxy using a Seestar, and I was satisfied with it until I saw this...

Looks pretty straightforward. Thanks for this!

How did you process this image, btw? I'm sitting on 10 hours of Seestar images for the Sculptor galaxy, and I'm looking for ideas. Cheers.

Eight hours! Kudos. And what a nice looking result.

You have a lot of detail here for 23 minutes! Shame about the satellite. Vive le Seestar!

Neighbour uncovers near-complete 7m fossil on western Qld property Discovered on an outback station by a neighbour and potentially 100 million years old, the fossil will be put on display at the Australian Age of Dinosaurs museum in Queensland.

Nice find in somebody's "back yard" in Queensland.

Hey Darren. Did you take a photo of M13 with your RedCat? If so, can you upload it here? As a Seestar owner, I would like to see the difference.

Thanks. I'm using a Seestar S50 myself. However, I admire the amount of time you are spending on getting your images. It's been worth it!

The central part looks like a cup!
Btw, what is the name of your tiny smart telescope?

I've done another, much better version. Slightly different angle for some reason.

The Eye of God or NGC 7293 really does have an eye shape. The central part is a circular shape with a green hue. There is another middle circle outside of this with a light coloured dust and then the outer part gives it the eye shape and is a darker orange colour.  There are a moderate number of stars through and around the nebula.

This is a Seestar version of the Eye of God or NGC 7293. It is a plantary nebula, found about 650 light years from Earth. 🔭#astrophotograpy #seestar #astronomy

M6 in this image is a group of around 20-30 stars that are about 1600 light years from Earth. It is not a tight cluster, and some of the stars form V shapes. They are surrounded by a blue nebulosity. In the top right-hand corner is more nebula, although it is more of a traditional brown-orange colour.

This is a trial of one of my first star clusters, M6. I've done a bit to try and highlight the nebulosity around the stars, but I might have overdone it. Still, it looks nice. 🔭 #astrophotograpy #astronomy
