The detail in there is amazing. Even the tiny NGC5474 is really clear. 👍

Thanks both. That's weird, my profile signature isn't showing on the post. I've got a SkyWatcher N200 (the old blue type) on a EQ-5 I've modified with steppers & belts run by Onstep. The camera is an Olympus E-PL5 micro 4/3rds that I've full spectrum modified. Also used a Baader MPCC + UV/IR cut.

So, whenever I'm imaging I start to worry that maybe I've messed up something in the setup. The longer I'm on a target for the worse I worry that I might end up with a whole nights worth of rubbish. I seem to have got into a habit of tacking a 'easy' target on at the end of the session so I should always have something to take away. Last week I grabbed 13 minutes of M13 at the end of the night. I thought it came out quite well for a consolation prize.

I've just editing the original post to try attaching the image in a different way. Hopefully that's cleared it up. Anyway, thanks for all your positive comments on the image (once correctly displayed!) I'm very encouraged. So, my immediate takeaways are: You can never have too much total exposure time, and I need to learn more about how the forum works. 😉

Thanks Craig. I did deliberately push the blacks down to help squash the noise but I think the compression that SGL's applied to the image is what's actually completely clipping it. If I zoom right in on the uncompressed version in the link I can still see faint noise. I was having some trouble getting a link to show an image in this forum, maybe I've still not got it right.

Hi all, Here's my first effort with enough patience to get a reasonable total exposure time - just under 4 hours after I'd filtered out the worst subs. Please point out what you think I could improve in my processing, which is exclusively in Siril and GIMP. Sky was Bortle 6 (according to Clear Outside) but there's loads of local lighting surround me. I had lots background gradient to remove. M101

I use Telescopius. It's google cloud storage behind it but it does much more than storage - helping you to chose targets, simulate framing, and automatically creates downsized versions of your images as well as keeping the full uncompressed available. It's free as well.

Hi Cyril. I've just reviewed the new Tutorial for the whole image processing using scripts and I think that it's a great improvement on the previous examples. The format is nicely step by step with clearly highlighted images of the UI. I also like that in the Image processing 3rd part that there's a recommendation of tool sequence. It can be very hard to understand the influence of the many possible sequences of use of image processing tools on the final result. That's a general statement, not just about Siril. I also like the new website look, very clean. I notice the the Wiki still links back to the old site though. Thanks for your efforts, I appreciate Siril as a competent and open source tool.
