I was pretty set on that uncooled 585. Not even sure if svbony do an uncooled 533.

I was seriously going to get this uncooled version as it seems cooling is maybe not as important as it was with these newer sensors. Especially after watching the long video sl900 posted. I may not even cool mine below zero for fear of frost on the glass. But I guess I have the option to cool.

Maybe, but I think they update parts of a webpage and not entire listing. It'll be just like Xmas wondering what's inside the box. Hope it's not socks.

thanks all for the help on this. i think i need to wait until i see what's in the package and go from there lol

yeah once i get the camera and up and running, time on target is what i need. you've shown me how i can stack multiple session (at least in a basic fashion) so i have no excuse. though it only being semi dark for just over 2 hours a night at the moment is a pain.

yeah i watched his video. he actually measures them too. i doubt the one included in my package will be that one otherwise i got an even better deal.

honestly im not too picky at all. i've seen some videos and remember 3nm bandpasses being 'good' but literally what do i know? im sure any dnb filter i get will be plenty good enough for me for quite some time.

that might be what im aiming for, but one step at a time.

yeah i think you're probably right, after looking at some videos and other stuff. besides, at the moment i really quite like broadband and LP filters seem to (have to) cut out quite a lot of that spectrum. if there is a cheap one in the package, no harm in trying it out but won't be using it right away.

er how would i tell? would having the ir/uv cut glass AND a ir/uv cut filter in the filter drawer be detremental? i mean it would at least be an extra peice of glass in the way of the sensor? lol, looking again at my order details, it possibly has a 7nm dnb filter included. 7nm isn't the narrowest, but it would be a start. ill be leaving it in the box to start with anyhow i've avoided even looking at how to process bnd osc data. im half expecting to find Schrodinger's cat in the box too, now. it says it has an ar coating and an anodised (sadly only dark grey) coating for harsh environments and a lives a longer lifespan hope that applies to me and not just the camera.

ill have a look into these. at first glance they seem a little more expensive and possibly complicated. ill probably start off with a more conventional dual band and go from there.

I have won 10 don't think I bothered deleting old version, but the constant reminder to upgrade on loading it stopped. If you just want to delete the old version, right click the shortcut and one of the tabs will say something like show target location. That should take you to the location on your drive of the exe file and stuff. Delete the folder that contains the exe and stuff.

ditto

i got the tec cooled version filter drawer and uv/ir cut filter for £514 including shipping and customs/taxes etc on my side. im not 100% convinced yet but 12 to 15 days time we'll see im sure its not as good as the more expensive brands - it doesn't have the 2 usb port hub built in - maybe it has that cooling fan vibration? but its a lot cheaper. its not annodised in a cool colour either

need to have a look into those. i (think i) understand using Ha +O3 the Ha goes into the red pixels and the O3 goes into green and blue pixels. But Hb is also red and not sure of the other popular (but weaker?) emissions. will go find some videos. its dawning on me i need to be a bit choosier on the videos i watch. i watched one earlier about gain and offsets and even i as an almost total noob noticed wrong info (which the comments pointed out that the youtuber had corrected in the video description) but who reads comments on youtube videos?

no mine will be the totally different svbony version and should have ar glass. there was a deal on to get a filter wheel and uv/ir cut filter. on a side note does anyuse use two different nb filters with an osc? or are the other possibly available emissions just to weak/difficult/something else for a noob and osc?

a surprising bortle6 but it seems higher from some of the gradients i get sometimes. but new camera, new start plus a basic lp filter from flo doesn't seem too expensive to not try out at some point. also a use optolong seems reasonable too maybe.

thanks so a light pollution filter is something i should consider using instead of a uv/ir cut filter for broadband imaging?

an rc is one of the scopes im possibly considering in the far future for galaxies and nebulas, so i'd be interested in seeing how you get on with it.

so i should have an uv/ir cut filter and filter drawer arriving with my 533 osc. let's not worry if its 1.25 or 2 inch in size yet. ill find out for sure in 12 to 15 days my future filter options are then a dual narrowband Ha +O3 . is this also what some people refer to as a "light pollution filter" or is that a another kind of filter? been watching some videos which confuse me.

not sure i can choose between them tbh they both look great in different ways.

Lol I'd need at least 2 or even 3 minutes of clear sky for that ;(

Don't remember how many subs but probably about 3 sec each via infra red remote. I remember clicking 300 times on some efforts. Pentax dslr and 50+ year old mint 50mm Pentax f1.7 probably wide open cos why not lol This one was after I got my mount and with canon 600d, probably my 40yo 135mm f2.8 and an intervalomter3 weeks later. I swore I couldn see a hint of horse head I've heard crack is nicer and cheaper ;( .

I'd love to image tho Ophiuchi but highest it gets is like 20 degrees for me so no chance. Tu for the link to data. Will have a good look and hopefully I will eventually be able to get my own data up to those sorts of quality.

Hadn't even considered edge of field issues of which I'm likely to have at least some. I'll definitely concentrate on non mosaics if my new camera turns up, but I'll try and take some test data to practice with whole I wait just 9 to 15 days M31 won't be high enough to image for me for at least a couple of months. I could always swap back to my dslr for m31 if needed, I hope.
