    Hi All,

    I have a strange one, that im really hoping someone can help with

    I am looking to use my focuser from the Orion ED80T CF on my StellaLyra RC6, as the stock focuser on the RC6 is total garbage and ideally, I don't want to buy a new focuser. 

    I saw the Baader Steeltrack focuser that is for refractors, has an adapter to fit the M90 thread on the RC6, so I am hoping that there is some other adapter to attach the focuser I already have

    The issue I have now is I don't know what thread is on the Orion scope and Orion themselves have no idea what thread it is... If anyone can help with this, I would be so grateful. Really want the RC6 going for galaxy season and really don't want to spend £330 on a new focuser haha

    thanks

    Get your local engineering shop to make one, or email https://moonrakertelescopes.co.uk/contact.html  and ask to make an adapter.

  2. If you have the funds and the space get a 10,  if it's pushing the budget and you haven't started collection eyepieces ( Good ones) get the 8, and an 8 with excellent eyepieces will be more satisfying than a 10 with mediocre ones.

    I have a 12" solid tube dob, it's massive and the base makes moving about in our garage where it has to live a pain, I built barrow handles with wheels at each end, and moving it into the garden is no problem however it's just the space it occupies when not being used when you open the garage door immediately the proverbial Elephants in the room, my wife hates it 😁

  3. Found a great seller on eBay, made an aperture mask for my Bresser 127 L, while  by no means does not show terrible amounts of CA Jupiter does get spoiled a wee bit, so for less than a pint of draught lager I thought worth a punt, I have to say it's very well made, shame matt black wasn't available so I'll flock it.

    I've had a look through some past sketchbooks but it appears I've never drawn Iota Cass. I have come across some other sketches of colourd doubles though, which might hint at what could be the issue.  In the sketches below you'll notice that the core of the Airy disc is almost white despite the star being strongly coloured. Only around the periphery of the disc was the colour more noticeable.  With Iota Cass being yellow, it's entirely possible that its brilliance overpowers its colour. By slightly defocusing the image, the colour hew blends across the image and may become more obvious. Hope this makes sense!
