Thanks👍

Thanks again Ciarán. Regarding Pixinsight, I use many of the modules and not all on every image. ArcSin stretch, star alignment, scnr, starnet2, dark structure enhance and the usual histogram transformation, curves etc. I don't bother with things like pixel math as I find layers in photoshop gives a higher level of control and is more intuitive.

Lovely wide field image, you have that Epsilon singing. Funny you should mention gain 0 vs 100 as I'm currently imaging at gain 0 and for now I'll continue to do so. Lower fwhm, longer subs and better star colour. As you already pointed out sky conditions may well dictate what is optimal.

Hi all, this is my effort at a 3 panel mosaic in Hargb taken over 6 nights from early February to early March. Total exposure time is just shy of 20 hours. The Ha was captured using a duoband filter in 300 second subs at gain 100 and the rgb was 180 seconds at gain 0. Takahashi Epsilon 160ed with the Asi2600mc Processing was done in APP, PI and PS. Hope you like it. Richard.

Love the colours Carole, groovy.

Great first light, congrats on the purchase and the corners look great.👍 How have you found it so far?

Might be worth pointing at again next year, get a few subs over a few months.

Thank you very much. No leakage problems here, it has been flawless from day one.

Would we see it vary over that short time? Might be worth a shot. How would I go about checking?

Yup we're mad, I often think about the money spent and wonder if it's worth the expense, but lets face it astrophotography is cool😀

Thanks Ciarán much appreciated. I've been quiet here too lately. Work is hectic and imaging conditions have been poor.

Yes, even 180 second subs blows out brighter stars. I don't worry about it too much.

Thanks, the rgb was captured without the 🌙 and ha with. Dynamic range is definitely improved at gain 0, fwhm is lower and sub exposures are longer. I will continue with gain 0 for now. Richard.

Thanks Michael, nice to get Hubble's Variable in there too. Thanks Daniel, yours look great. Thank you Mike.

Managed to get a couple of hours of Ha on this.

You need to give that sensor a good clean, look at all that dust. Stars are great improvement too.

Thanks, glad you like it. Fast optics really help and the Imx571 is a great sensor.

Lovely, second image has a better colour balance.

Thanks, I could've got more but I had to be up for work. I think it stayed clear here until 03:00

Looking great so far. Should be a cracking image when complete.

Nice, great FOV.

I'll keep an eye out for that.

Hi all. The fruits of Friday nights clear sky. This image is the first pane of a planned 3 panel mosaic, hopefully I have time to finish it this year. 4.5 hours rgb in 180 second subs at gain 0 with the Asi2600mc through my Tak Epsilon 160ed, mounted on my AzEq6 I had a little Ha from a few years ago which I added in, unfortunately it didn't cover this FOV so I added it selectively to the cone area mainly. Processed in APP, PI and PS Richard. Added Ha

Did it stay clear all night? had to get to bet about 01:00 with work this morning. Still one pane of my three panel done. Looking forward to seeing your results.
