Thanks Chris. Will be nice to try with the Edge 8 if we get the chance

NGC7331 is about 53 million light years distant and appears small through my 100mm refractor. This is a hugely cropped image. I must have another go with a larger scope

When stars go BANG!
Managed to do a bit of imaging last night.
This is the supernova SN2025rbs in galaxy NGC7331 in Pegasus, which outshines its host galaxy of thousands of millions of stars.
Taken with an Esprit 100 refractor, ASI2600MM camera and LRGB filters. Total integration 1h 40m.

No worries 🙂

Yes, the running man is more of an impression to me.
For what its worth, this is how I see it!

🙂🙏

Lovely 👍

You look a bit grumpy Martin. Cloudy I presume? 😄

Thanks

Probably. Most nebulae shine very faintly and our eyes are not good at detecting colour with faint light. "Emission" nebulae shine by the ionised hydrogen gas being excited by starlight which causes it to glow red. "Reflection" nebulae shine by reflected starlight and are bluish.

Youre welcome

Pleased you found me 👍.
Yes, these days, you can never be sure of the source of what you're looking at!
The methods and equipment I use are fairly standard within the astro community 🙂

The technical stuff is just the means to an end. It's the end that matters 😄. Pleased you like it 🙏

The Hubble palette was made popular by the Hubble telescope and the blue/gold colours are characteristic. Some people love it, others hate it!
Without SHO filters, most nebulae appear reddish, which is the dominant colour with 'normal' visible light. Your N.America image shows this well

The sulphur, hydrogen and oxygen filters capture light at 3 specific wavelengths and are recorded in mono. The blue is light recorded with the O filter at about 500nm wavelength.
The image uses the "hubble palette" where the 3 mono images are coloured red, green and blue respectively and combined

Cheers Vicky 🙏

Thanks Bob 🙏🙏
