CheshireChris Posted September 26 Share Posted September 26 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. 16 1 Link to comment Share on other sites More sharing options...
Mr Green Posted September 26 Share Posted September 26 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! 1 1 Link to comment Share on other sites More sharing options...
Vroobel Posted September 26 Share Posted September 26 (edited) 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. Edited September 26 by Vroobel 1 Link to comment Share on other sites More sharing options...

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. 10 minutes ago, Mr Green said: That's a very nice first attempt! Especially with such a short amount of integration time.

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 🍸 Chris 2 Link to comment Share on other sites More sharing options...

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.

I think it's a matter of establishing a workflow. Try using BlurXTerminator first out of the 3 plugins and shrink the stars down a bit. That alone will make this image pop more.

Mine looks like an image taken with a potato using cling film as a filter. Link to comment Share on other sites More sharing options...

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!! 1 Link to comment Share on other sites More sharing options...

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. 1 Link to comment Share on other sites More sharing options...

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. Chris Edited September 29 by CheshireChris Typos & clarity. Link to comment Share on other sites More sharing options...

The prices seems to be going up as well.... 😪 Edited September 29 by Spad Link to comment Share on other sites More sharing options...
CheshireChris Posted September 29 Author Share Posted September 29 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.. Chris Link to comment Share on other sites More sharing options...
Elp Posted September 29 Share Posted September 29 Sy135, get the videography one (vdslr), far cheaper. If you know you know... 1 Link to comment Share on other sites More sharing options...
