M31 - 1st attempt


Recommended Posts

Images shot 12-13/09/2024

100x60s lights + flats/bias/dark. Not sure the darks were really needed for my ASI533MC, Gain=100, Temp=-10degC

Processed in Pixinsight - took many attempts; all part of the fun 🙂

Not without issues, some stars look a bit bloated but overall I'm pleased with it.

That's a very nice first attempt! Especially with such a short amount of integration time.

You don't need darks with the 533MC, I'd just stick with taking flats & bias although you might get different opinions.

If you're using Pixinsight, I'd suggest a free trial of BlurXterminator as that will make a huge difference to the stars in your image.

I warn you that once you try it, there's no turning back!

Indeed, it's a good image.
I have two thoughts. First, could you try to make the galaxy dimmer? Second, the nucleus shouldn't be such a point-like. ;)

I have all three of rc-astro plugins -  I used BlurXTerminator (correct only) right after doing SPCC, then NoiseXTerminator. I think it's a matter of establishing a workflow.

The clouds rolled in and stopped me doing any more - otherwise I'd have let it run for another couple of hours

Oh, Me and my bank balance are well beyond that stage....😯

Don't know why it's so bright - the brightness seems to have increased after l exported the final image as a jpg from PI, then opened in Photoshop and cropped it a bit. I'll have a play with it. Not today - PixInsight has broke my brain and I'm in serious need of a stiff Gin Fizz 🍸

No one does the 70's colour pallete as well as you! Give Pixinsight a go, as Chris mentioned, you just need to establish a workflow and once you've got that nailed down, you can start adding a bit more complexity.

Try using BlurXTerminator first out of the 3 plugins and shrink the stars down a bit. That alone will make this image pop more.

You've got a good eye! I was too focused on being impressed with this being a first attempt.

Mine looks like an image taken with a potato using cling film as a filter.

New mount first :(

Fantastic! I don't see any bloated stars, just a reeally tiny bit of CA and of course the diffraction spikes. Amazing result from a small camera lens!!

I like the spikes if they come from an unmodified OTA, but they should be perfectly perpendicular, narrow and sharp spikes from Newtonians or RCs, or multiple spikes from lenses while they may have weird shapes. :)

Fantastic!!! Great image.....

Was it a camera lens?

Thanks

Yup, the manual Samyang/Rokinon 135mm f2 - it has a very good reputation as an AP lens - there is an extensive thread on SGL --> Samyang/Rokinon 135mm Imaging - it's so popular that there a lot of AP specific accessories for it. The manual Canon fit lenses can, however, be hard to find these days.

And they're not cheap.... I have been looking for one. The prices seems to be going up as well.... 😪

Wex are knocking them out at £473.

I already had mine before starting Astrophotography so it didn't factor in to the cost. If l was starting out now l'd probably get a 'proper' scope - something like the Askar SQ55 - which can double as a camera lens..
