2 bortles is a factor of 8 compared my bortle6 back yard. So if it were me I'd need to know if that extra 0.3 increased the factor of 8 enough to outweigh the 60 minute drive, lack of room service scary sounding eastern European wildlife lack of mains power and travelling family / companions I think I'd settle for just 8 times faster photon gathering Enjoy your trip!

I'm finding background neutralisation and non photometric colour calibration helps. I still use photometric too. Graxpert seems a hindrance at the moment it seems to some remove detail during background extraction and also does some kind of weird stretch and green tint when saving out. Also a bit crashy.

Ty for your kind words I'm trying my best not to look at others' images of my targets until I at least have a go myself. Nina's framing assistant ones don't count. I thought it looked ok in brown for a little while..... I managed another 90 ish minutes before rain last night, stacked them ok (there is a slight seam in histogram view) but graxpert background extraction seems to do a good job on the stitched result of both nights, I think it's removing some detail. Need to experiment a bit more before I can put another less brown version on here.

Keen to see how you get on with it.

Thanks both. Will see what I get with five hours.

I'm aiming for 10 hours total. Might need more though.

This is very little data, I was only bothering with it so much because it's been cloudy. I was worried about the colour, but not so much now. Just need to test I can do this with two sessions. Ty for the help I think colour correction and photometric colour correction in siril achieved at least a measure of what you recommendend. As for the background, hopefully more time on it and it might improve. Maybe.

doesn't flat space suggest its infinite though? curved space would suggest its finite.

ok final flogging of the horse with this one. my latest result is bluer but has some cartoon binocular gradients like a lobe around the right and left half of m31. unless they're stars? anyway, hopefully that will be reduced with more time on target. about 38x60sec one panel and 44x60sec other panel.

this shows me its heading the right direction. more time on target it is, i think. bit more drama, less "smoke from forest fire" discolouration

I paid the £2 extra at checkout for all tax included. Royal mail delivered it, no additional charges. Support from china is not ideal, but svbony got back to me with questions via email quick enough. If you're Nina based, I'd be interested in your offset. I used Cuiv's method and settled on 5, not 50 which seems common for other 533 based cameras from other brands.

well you made me decide to try harder, and i decided to randomly try photometric colour calibration AND (non photometric) colour calibration and background neutralisation in siril and seem to be getting somewhere. of course, it could all result in a hot mess of pixels but it at least looks more the colour i would expect. maybe btw £460 for the sc605cc and a free nb filter sounds a really good deal. and i thought my deal was pretty good

all you did was use "star colour calibration and some gentle enhancement of saturation"? ffs i don't want to have to learn APP too i wasn't even referring to my brown stars ill try a photometric colour calibration in siril see if that has a similar effect to what you got. my image is surprisingly similar to your first one, so my result is not terribly unusual or anything? thanks for sharing this btw. and yes i need more time, preferably later in the year...

just in case anyone still reading/interested, i took a chance on https://www.aliexpress.com/item/1005006168144099.html?spm=a2g0o.order_list.order_list_main.5.21ef1802HNkZUf 7 days shipping, base of guide scope should slot in and ill try and glue a mini pc to an upside down dovetail clamp and plonk that on too. not certain about screw size/length to screw this to the two holes in my ota rings yet the deciding factor was the first user review and image "The center of the yakisna plank. I made it possible to know the good work of the trimannia of the trumpet and the security of the trumpet and Gida."

i believe you. i've just really really unsaturated it across the board and it might look better. thanks for this, i don't have app but i will try something (maybe) similar in siril

My best m31 image seems very brown. I'm hoping this would improve as I add more time to it? Or is it because it's low in the sky? Or me just being bad? Others' images seem silvery blue but if I turn down saturation mine just goes monochrome ish. Could a low off set effect this?

Not keen to look at my scope too closely. With sw QC no idea what I'd find

No so far seems great. Did a sharp cap sensor analysis. No band but only done one minute darks but their histogram looks normal. Also quick test stacks on veil nebula and m101 and a meh 2 panel mosaic of m31 I set my offset to 5/100 which might be low...

And full of clouds

I'm bortle6 72mm and 5.8 so probably works out similar though I'm not looking out to sea maybe slightly in my favour as 1 bottle is 4 times ?

I almost can't believe that last image only took 90 minutes. NB filters are on my list. Maybe I should avoid it in broadband until then....no clear nights makes it an easy decision also that last shot almost doesn't look like NB as you have what looks like a wide spectrum of colours in it, which I really like a lot

I've seen one video and looked ok. At least once I get data I can try the options.

Was going to try using the Ha as luminance in lrgb composite

Cool Ty. Single subs are ok? Will try this asap M101 straight up ish. Veil is lower to east. I can do west near meridian easily when I do phd2 calibration

I don't disagree, but how do you distinguish tilt from tube slop? I think I have both but not certain. I don't want to start messing with tilt screws if it's focus tube slop Also could imperfect back focus impact this? If all the other items in my optical train are accurate I need another 0.3.mm back focus to account for filter
