hello again just looking for some advice. https://www.svbony.com/sv705c-color-planetary-camera-imx585/#F9198J-W9184A seems like a bit of a bargain for the next 3.5 days. camera, filter drawer and a cheap uv/ir cut filter for like £252. maybe + postage and brexit import tax. its not cooled and probably doesn't have a heatsink like the player one version. but its cheap. im sure it won't be as good as a tek cooled one from somewhere. but its cheap. this would be a decent upgrade from my dslr and i could get a 1.25" dual narrow band in future when funds allow? i could maybe manage the heat by doing (for example) 30 second exposures and a 5 or 10 second wait for the next one? (the joy of nina sequences). im assuming this includes everything i'd need to slap it on the back of my flattener (i've emailed svbony to ask same question but i doubt ill get a good response before the 3.5 days offer expires) https://www.firstlightoptics.com/stellamira-telescopes/stellamira-2-inch-field-flattener-with-m42-adapter.html?_gl=1*vehb4c*_up*MQ..*_ga*ODgxMDY2OTM2LjE3MTc3NjU3ODA.*_ga_F6VGWQ0MW9*MTcxNzc2NTc3OS4xLjEuMTcxNzc2NTc4OC4wLjAuMA.. also, i'd never need to use a dual band filter AND the ir/uv cut filter at the same time, right? cheers in advance.

I read somewhere a while back that some type of radar is being developed that used some technique sounds similar to this.

You won't know what colour it is until you observe it.

2 years should be plenty of time to plan and perfectly execute the required bank heist

i hope they checked their usb cables. its always usb cables.

id settle for basic accuracy, some semblance of impartiality and investment in spell checking. what concerns me is future governments will do the same, now, because "they did so why can't we"

i hope you're doing ok after your treatment. im old too but have been lucky so far. i was very tempted to by the zwo/asiair route but lack of funds made me have to use an old macbook running windows i still wanted to keep my options open so i got a zwo guide camera just in case. im still using a stock dslr, and that is my next upgrade, one day i have the swsa gti too and while im sure its not the greatest mount in the world, it seems more than capable at least for us noobs. i really dislike the altitude adjustment bolt, it always seems to have a dead spot where it turns freely just as im getting polar alignment bang on. works well with nina though so far.

same sensor but not cooled or tec cooled. im sure the ZWO ASi585MC is far better, lower noise due to cooling and probably better software/drivers too. but that costs money also the zwo lock in which is bad, but, asiair looks extremely user friendly. i have a zwo guide cam and if i didn't like Nina so much i would jump at an asiair and zwo imaging camera. im new to this hobby so bare that in mind when reading my comments

looks really good to me, especially for a mess around. sadly m31 still not high enough yet for me. was looking on svbony's site and noticed 3 days remaining 30 per cent off on https://www.svbony.com/sv705c-color-planetary-camera-imx585/#F9198J its not cooled but it seems a really good deal. cuiv the lazy geek did a comparison on noise between same sensor tec cooled and uncooled and he saw a massive difference. via youtube i couldn't see any difference.... if i could quickly sell one of my livers it looks a bargain for £220. probably plus delivery and brexit tax and other things.

bbc has dropped in quality massively over the last 14 years or so. its now basically little more than a government propaganda outlet. bbc now seems to stand for Bread Before Circuses just needs regular songs to the dear leader and the North Korean state broadcaster would be jealous

Lol you're absolutely correct. I downloaded a couple of the RGB only datasets and didnt get much further. I've seen some YouTubers link more suitable (for me, hopefully) and will give them a go. Also some people on astrobin? I still need to find a Goldilocks tutorial on gimp on masks and layers and stuff.

i was tempted to ask if anyone knew a good source for data to play with. this is really handy ty

its more the risk i'll knock it when setting up/down, which im very likely to do.

Great result. I think your trial worked 😀

I have vaguely similar gear and thinking upgrading my dslr to a imx585 based camera and would love to see your results.

Yup. I really don't think they're a good idea, but, for some people they are invaluable.

i joke, but with chatgp it might not be that far away.

i just say "Alexa process my image data from last night" and come back 3 minutes later and its all done.

cheers

just want to check at what point i should bin 2x2 - after stacking but before gradient removal?

i really really don't have the money for a mono + filters set up though so i think a osc and filter + drawer is a reasonable compromise. well, more of a hope i guess. but even that is out of my reach for a while.

yeah i don't like the cold but at the moment i can have everything outside and plugged in ready to 3ppa in 8 minutes after the sequence is going i can sit inside and maybe even risk sleeping for a few hours.

nice. also nice neat looking wires too.

im certain you're right about imaging time, but when i took this, there is no astro dark and the 'next type of dark' is about 1130 to 230 and the number of stars in my subs according to nina was about 550 at 2pm and by 215 it was 18 stars i did save my sequence, so i can resume as soon as there is a clear sky, but doing it 2 hours per night is not great to be fair, it was more of a test of "can i even get anything" (like my ngc7000) and it seems i can, just about. but need a lot more time especially with no astro dark.

holy smoly that's lovely. its broadband right? and i agree i need an astro cam but need the funds first. also looking into them a bit more im not sure a imx585 based one is as ideal for me as i thought. so im thinking zwo533 (i think it is) with the square sensor, but i don't like the aspect ratio. looks like 1980s television. having said that, i've only just noticed your amazing image is square, so maybe it doesn't really matter to me after all.
