Two nights on Orion Nebula framing changed on the second night sadly leaving a smaller fov approx 4hrs ,30 sec subs zwo533mc cls filter, 200pds 

I’d bear in mind if using usb3 you really need pc to be close to mount if using high frame rates within 2m thats what I’ve learnt using a zwo 585mc .

Thanks A Million, thats amazing.

I think you just answered a bunch of questions I didnt even have.

Out of interest,  any idea how much the cam and lens with the ZWO connector weighs?

If I go the Player one version, Im thinking Ill just connect it via the 1/4" hole on the back but worried it might be too heavy all up.

Thanks again

Chris

Zwo585mc, lens adapter and lens weighs 418 grams or 14 3/4 oz .

That says highly elastic though, is that what we want to hold the mirror? Would assume that moves more during meridian flip?

Highly unlikely 

you want low modulous silicone , Screwfix sell it it more the normal stuff these days it will say on the tube like the Screwfix version 

I believe there is a flocking material that blocks 99%  of light too , expensive though , I see if I can find it .

Or black3.0  absorbs 99.% of visible light even blacker than  vanta not sure how far 150ml will cover , black 2.0 available too

Hi, May I ask how you connected the cam to the nifty fifty and how you have it mounted to the base plate (dovetail bar)?

Is it just connected with the ZWO EOS-T2? Any weirdness with setting up or spacing?

Im about to pull the trigger on the Player One version and I would like to use the 50mm lens and also connect to my SW 72ED w/ reducer.

Regards

Chris

Hi I bought a follow focus adapter from Shapeways to fit my nifty fifty  EF mk2 1.8 lens https://www.shapeways.com/product/9ZMKHDM3G/nifty-fifty-canon-50mm-f1-8-follow-focus-adapter

connected to a stepper motor via a 151 6mm belt https://www.ebay.co.uk/itm/173640532294?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=4KixEfdrSPu&sssrc=2349624&ssuid=xQsxeo45SGa&var=&widget_ver=artemis&media=COPY

camera connection is via a zwo lens adapter

camera sits in an adapter a friend kindly made me , which then fits in a zwo 78mm camera holder , I will take a closer picture to show how it fits together .

dovetail is a losmondy style diy job made from 20mm black plastic sheet .

I usually use 25. Its something that I am confused by as well. All I really know is that you should ensure your histogram is off the left edge, and that its not so far right of the left margin that its clipping on the right hand side. I would be curious to hear others with much more expeirence than myself have to say.

While I am here I may as well share a little mosaic I did with the Uranus-C with my 150p of the Carina nebula:

Nice image I’ve currently got mine zwo585 coupled to a 50mm nifty fifty lens  though need to try at F4 as f2.8 no good but a friend recommended try f4 

 Does anyone know can you get a bahtinov mask to use with a 50 mm ef canon nifty fifty lens (attached to zwo585mc).

Using the zwo585mc for imaging is there a recommended offset ? or does it not matter currently I have it set at 3 offset .

I’ve used a telegizmo for years now , if I haven’t a scope on mount I put one of those collapsible round garden bins over first then the telegizmo over and jam something at floor level for air flow , if the newts on the mount not much issue as cover well off ground and plenty of air flow , sometimes I leave the primary mirror fan on just to keep air flow.

If you use the M48 fitting the backfocus becomes 57.5 mm +/- 1mm probably more 1mm rather than less  omit the two spacers use just the main cell

Can you link to this please?

I ask because the only one I recall was an issue with a set of "older" flat darks that had pixel values higher than the darks. When they took new flat darks the signal levels matched and the calibrated output was fine. Point being it was not a config issue as such.

Probably these ones there is three , worth watching even if not a PI user .

When I use a modern lens I use manual focus as I want to control focus and not have the camera and lens decide to adjust focus mid capturing

Hopefully the autofocuser will sort focus out .

Thanks @ollypenrice  I wouldn’t have thought of doing that , half expected an F number to set lens at ,never used a lens for Astro before .

I have Deepskydad Af3 on a  baader steeltack  , just drop pavel an email he really helpful and there is no focuser he can’t fix onto if there is he will 3D print one , I have three dsd focusers on various scopes .

I’m currently building a imaging train which I’ll consist of a canon nifty fifty 1.8 Ef lens connected to a zwo585mc, with autofocus and guided what aperture setting would be recommended to set the lens at ?.

Yes it’s the standard camera/tripod thread. 1/4 Whitworth fits too. Ebay is a good source

Mark

Thanks for that .

 Help required on the back of my zwo585 mc is a screw hole which I believe is 1/4 -20 unc  is this correct? does anyone know if there are any local shops that sell this size or will I need to order off the internet .

  +Astrosurface  limited use of it but does seem very good  , does stacking and wavelets ,few videos on YouTube if you search .

Here are my settings, maybe need 115,200 as the baud rate???

 Thanks  my  old Eq6 ,9600 baud rate which connects at that , my board  connects using the usb to serial cable not the newer usb board which I believe works at 115,200 , in Eqmod  I used to have pulse guide rate at 0.8 for RA and Dec do I need to adjust similar to yours at 80% for Ra and Dec guiding rates ?

Hi everyone i downloaded Green swamp software so going to give it a go  and have configured to use with my EQ6 pro +APT /phd2  have ticked reverse dec output after meridian flip/CDC  , setup a new profile for guide camera in phd2 , and have mount connecting and all the software  ,Can anyone tell me if my settings look correct?
