Astronomy OFFIMG's

Post by rudi »

Here's an image of the Fireworks Galaxy, NGC6946.

Image

Funny how it looks much better when actually in the DM42 ;-)

The image is from a picture I took about a month ago, the original image is here:

I will post more astronomy OFFIMG's in this thread later on ;-)

Btw - this time I used the dithering function in Affinity Photo, which does a great job.

Great pictures as before! I think NGC6946 is better suited for offimg display than the horsehead.

That's quite a serious telescope you have in your back yard if you can image the Horse Head Nebula like that! :)

Please do share more such images, lots of fans here besides me.

IDK the image Walter refers to by its catalog number, but no doubt I will by the image... ;)

Thanks for sharing!

Agree - the Fireworks Galaxy looks better.

I guess amongst amateur astronomers it is very average, a 10" newtonian telescope with a little extra necessary gadgets attached ;-)
Here's a fresh image from tonight, it's a clear night again tonight. Now the telescope is acuiring images for an exo-planet transit.

rudi, do you find Affinity Photo worth the money still? The reviews have seem to head south on the AppStore. I had dismissed it until you mentioned the dithering option.

Here is a comet photo I took in 2019 with my Sony and 300mm Cannon.

PS Your photo conversion of NGC6946 is AWESOME!

Yes, it is definitely worth the money. Not as good as PS and LR, but they’re also in another price group.

I mostly use AF for family photo editing, only very rarely to Astro photography, for that I use AstroArt.

Thank you. I am referring specifically to the dithering function and export to BMP. Does it export directly to BMP? PS does a horrible job at dithering. I am running my images through Hyperdither first and then to PS.

Here's an OFFIMG of some sunspots from sunday.

I've used this crop and dithered it using Affinity Photo
