Yeah I've seen few videos that mention the tilt, also the camera hanging off a 5mm connector. But not entirely sure what they mean. When I try slapping it all together tomorrow (I've pre prepared my set of highly calibrated hammers) I will do it on a bed for safety;) I might have more context after that

Apologies, might have to ask you more questions once it arrives and I've googled nosepiece

No idea which version I'm getting. They seem popular so I assume I'm getting a later one. I'll attempt assembling it all without the rotator and see if I can focus. If I feel the need to rotate, I'll try rotating the OTA in it's rings. Would the rotator be suitable if I get a osc in future. Ty all again for the help. About to Google "my first telescope help"

its the one on flo website stellarmira. i'd hate to send the rotator back but if it rurns out i could do with out it that would be ace. im not sure how much i'd need or want to rotate. https://www.firstlightoptics.com/adapters/sky-watcher-evoframe-camera-rotator-for-evostar-72ed-ds-pro.html https://www.firstlightoptics.com/stellamira-telescopes/stellamira-2-inch-field-flattener-with-m42-adapter.html

it will help if you're suggesting i copy this but modified with the bits i don't have? could be a great help ty

just thought i'd mention this is my first telescope, so i might be a bit slow on the uptake of any advice

hello again has anyone tried using all three of the above together? is it possible to achieve decent back focus using this combination?

Yeah I just been looking, some are not too bad, plus I have a lion from a golf trolley might have potential. Probably only potential for fires though With my upgrades I should be able to get acceptable results.

In an ideal world I'll get a cooled osc but keep my 600d and get it modded. That way if I ever have an opportunity to travel to a dark site, my entire kit can be battery powered without needing a huge portable battery power supply thing

Hey I really appreciate this it really explains a lot. I think for me, though, I don't like f stops as they can't be compared on different lenses. I've avoided exposure compensation on my dslr (mostly) but will get a budget telescope soon with (obviously) a fixed aperture. I'll try not to accidentally switch exposure compensation on my camera. One day I will get rid of dslr and get an im585 cooled osc. I really like the (from my noob perspective) the small fov it gives. In the meantime I can perfect my telescope and guiding skills. I'm sure there will still be plenty of headroom for me to improve my results before I even get the osc

Yeah I was really asking but knowing the answer I'm trying to use my very limited budget to get the biggest improvements to my end product. I'll have to stick with unmodded dslr but get a scope, guide cam and scope and the required bits. Also my £5 flea market tripod maybe iffy with more stuff

Do you think I would be able to get away without guiding? I seem able to do upto 5 mins unguided if I take care with setting up, but that's at a much much bigger fov.

I've been taking all calibration frames, except dark flats with my dslr they clearly are great at improving end result when done well and I love how Nina organises them. First time I tried using dark, bias and flat in a Nina sequence I couldn't work out why Nina would only show 0.0 in the exposure length field for bias and flats, so I gave up and used my intervalometer. I think If I made a poll called "what's the longest time you've kept your gear together without making a single upgrade/change" ..,....I wouldn't want to see the results

I have recently struggled with plate solving, before eventually solving it by removing the lens cap. Also spent twenty minutes trying to focus a star before realising it was a reflection of a street lamp in kitchen window. I'm at that sort of ability level. But I'd rather fail at something a bit difficult than a bit easy.

Also I've never taken dark flats, but do take flats, bias and darks. Mostly. Not keen on flats as it is though. On an actual telescope I'm even less keen.

Ty all for this. It seems the sensor it uses is suitable and should be ok with the 72ed and a noticeable upgrade from what I have. Assuming I can get it all connected up and working Should I be unduly worried about plate solving at such smaller fov? It looks pretty extreme to me, but I'm guessing there's people here who would still think of it as wide field? the main reason I'm still considering it is m51 looked big and m31 might just fit in. If I did get the 72ed and 585mc I can get a guide scope and guide cam or a tripod. I'm assuming at this fov, guiding would be a necessity?

Yeah I initially tried to guestimate a CF from relative sensor size, but astronomy tools correctly showed a much smaller field of view than I'm used too. Zwo 585mc is a planetary camera and the only option in my budget, so I'll have a rethink. Ty for this

Trying it now seems perfect ty Lol the 585 isn't square as I thought but the smaller field of view I like Dunno if the numbers make it a suitable match or not. That is a much smaller fov then my current lens and camera, not sure I'm good enough for that bigger leap. also intending to get a guidescope and cam and will need to work out if the flo £200 bundle one will do.

Currently my best lens for ap is a 200mm and with my 1.6 canon crop is effectively 320. I'm struggling to compute a roughly equivalent crop factor for the zwo859mc. Will plug info into stellarium hopefully for a comparison

My only xp is with 600d which is 3:2 and makes me want to be able to rotate for framing. A square sensor maybe the need to rotate is diminished a little. Looks like I'll lose 10 megapixels though.

Sounds good to me Ty. A cooled osc is way beyond my budget. I'm looking at zwo 585mc on flo website about £400. I have seen a couple of videos of some £500 Blue cooled versions on AliExpress but I'm not keen.

Wow fantastic explanation Ty so much. I'll stick with latest plan of osc and sw 72ed then Have you seen videos of people using smaller pixel (planetary cams I assume) for DSO imaging?

wow some fantastic info here i had no idea about ty. one of the reasons i'd like to ditch my dslr and go over to a osc camera is to capture some Ha but this makes it sound like i would need a mono camera and multiple filters which i don't want to do for a long time. should just stick to my dslr if im going to filter out ir spectrum?

Cheers for this. Software does seem ok at removing it. Why ir cut though? Wouldn't I want ir with a osc ?

I'm about to get a zwo 585mc (and 72ed) and am clueless about what filter to get. Would Astronomik L3 filter screw in so I wouldn't need a drawer (seen videos saying back focus is tight)
