I'm selling my brand new-never used QHYCFW2M-US filter wheel for 8x1.25" mounted filters.
It will be shipped in its original packaging (with extra packing of course) with all the components that came with it included (cables, adapters, screws, etc).
If you have any question/s please ask.
Price: 250£ + shipping-fees
Thanks for looking!
So i have a new project coming up i want to raise funds for so im having a bit of a clearout of some astro stuff ive not used in a while (upgrading as i go along)
TS Optics low profile off axis guider, comes with canon camera fitting, spacer and 2" nose piece currently at 159 euro on its own on telescop-express, willing to accept £100 the lot **EDIT now avaliable again****
Meade DSI colour ccd camera. This is the original version not the pro, i have been using it mostly for guiding as its a nice sensitive chip, £30 ***EDIT sold, thanks!****
FLO premium Cheshire, good condition £20 ***sold
Skywatcher 1.24" light pollution filter £10 **EDIT now sold, thanks Frank the Troll***
Skywatcher 2" light pollution filter £15 ***sold
PM for details happy to chat about postage as well
I scrapped all the Oiii and Sii data I previously took during a full moon (about 15 hours worth) and retook it all when the moon was a bit smaller at 76%. Ha was taken during 98% and 67% moon. All the lights were taken on the following nights: 12th, 19th and 20th September 2019.
Integration times, all in 600s subs unbinned:
Ha = 28.33 hours
Oiii= = 5.67 hours
Sii = 5.67 hours
The Ha data is really nice, and unsurprisingly the Oiii and Sii is not as strong (or nice).
I'm missing that (vital) step in my processing routine of getting the Sii and Oiii properly stretched to match the Ha, before combining. I dont really know how to deal with the weaker data properly. Any pointers would be appreciated.
What I do currently:
All the data is loaded into APP into separate channels/sessions.
The data is stacked and registered against the best Ha sub
This produces individual stacks of Ha, Sii and Oiii that are all registered
Each channel is processed with DPP in APP and then saved as a 16bit TIFF
Each is opened in PS
Stars removed with AA and any remnants removed and tidied up
I then open a blank RGB document in PS
I paste Ha into Green, Sii into Red and Oiii into Blue
Adjust the selective colour settings to get 'Hubble palette'
Adjust levels, curves, saturation until looks ok
All the Ha Sii Oiii data is then combined together in a single 'super' stack in APP using quality weighted algorithm to create a 'luminance'
That luminance layer is adjusted using levels, curves, and NC tools such as local contrast enhancement and deep space noise reduction (using masks to apply as required)
The luminance is pasted onto the above colour layer, and incrementally added using gaussian blur
Cropped and saved.
Here it is anyway I haven't intended on any more exposure time for this one, but will consider it, if the expert opinion dictates otherwise!

Okay, I'll try to make this as short as possible.
Info: I have a EQ5 mount (soon to become motorised and GOTO'd) and, after reading countless astrophotographers praise the QHY PoleMaster, I thought it'd be a good idea to follow in their footsteps and buy myself a PoleMaster.
I saw nothing about the PoleMaster supporting the EQ5, so I thought I'd ask whether or not the PoleMaster would make my life easier by supporting the EQ5.
