  1. TS-Optics T2 Thread 360° Rotation and Quick Changer now installed

    I removed the 16.5mm ZWO M42M-M48F spacer that I had in place and replaced it with 
    TS-Optics T2 Thread 360° Rotation and Quick Changer and
    TS-Optics Adaptor from M48x0,75 to T2 
    5mm T2-T2 spacer


    I've got Baader spacers in place to get me to 44.5mm
    Once the weather clears and I can get out into the field then I'll know for sure how far I'm out on spacing and then add/remove spacers as needed

    Yeah, there are some issues as you go toward the edges... same happens to me despite having replaced the canon mount by the Astro Essentials M48 Adapte, I'm still trying to get the optimal backspace. But... the image looks fantastic! Love it. No need at all to go 1:1 to enjoy it.

    Could you please share what SHO filters (brand, diameter, bandwidth) are you using? Thanks a lot :)

    Thank you

    These are the filters I'm using (see photo). Working out ok so far

    I'm  about to also pick up some RGB filters from the same brand

  3. It was a clear night last night. Managed to capture around 7 hours of photons on IC1396 and SH2-129 with the Samyang 135

    Initial post processing with no noise reduction yet applied.
    Had to discard a few SII subs as dawn approached and the target started to disappear behind my neighbour's roof

    Close inspection shows that some tilt remains in my image train
    Will hopefully deal with that once my new lens adapter from FLO shows up

    With about 5 more night's worth of data yet to be processed from the past couple of weeks, I'm looking forward to the "final" iteration and hope to tease out "the squid" (OU4)

    Taken 17th/18th October 2022 from my back garden

    You should be delighted with that image. I love the subdued colours and the framing with the Little Rosette is perfect - you've managed to achieve some real depth in the centre of NGC7822.

    I took a look close up and be careful with the noise reduction - it is introducing some unwanted artefacts.

    What method did you use to reduce noise? This sort of thing call also arise with star removal.

    I know you/I shouldn't pixel peep so hope you don't mind the comment.

    Hi Adrian

    My image posted here has no doubt been munged by my iPad after I tweaked brightness/saturation/vibrance/contrast before uploading here so will no doubt suffer from compression on close inspection/pixel peep

    As the image came out of Pixinsight untouched by iPad, noise reduction used was MLT and also SCNR

    Original jpg export of xisf image direct from Pixinsight attached here as a reference

  5. Saw first light with the new setup this past couple of weeks. Loving this lens

    Just now waiting on the Astro Essentials Samyang Lens to M48 Adapter from FLO , but for now using the somewhat "wobbly" ZWO EOS Lens Adapter

  6. Here's my "solderless" version; just now got this one assembled this morning for a 135mm lens setup

    Did a couple of iterations of the enclosure "faceplate"

    Also running another one I made earlier on a refractor
