Thanks for the heads up and I’ll look them up to see what they are like as I’ve never tried them

Are these Celestron eyepieces another copy of an existing eyepiece?. The Ultima Duo’s were apparently just repackaged Hyperion eyepieces. My understanding is that they are relatively new. Has anyone had any experience of these or of the eyepiece that they are repackaged from? Thanks

Hi 👋 and welcome to SGL. I would definitely point you to the 8” Dobsonian (200mm) The Skywatcher 8” Dobsonian are in stock at the moment at First Light Optics (FLO) and meets your budget of being under £400. I would advise against observing out your window as your garden is much more suitable. Good luck in your endeavors

Hi 👋 and a warm welcome to SGL

I found them on eBay ay

Yes it’s definitely an old style Skywatcher 6” refractor (150mm) and as previously stated from the Evostar range. The scope needs a lot of TLC to bring it back to being useable. The big lens in the front of the telescope is the most important part, and it’s condition is crucial. If the scope was stored somewhere damp then this can badly compromise the lens. Take the black cover off the front to get a look at the objective lens. Until the condition of the objective lens is determined it’s not clear of the best way forward

Hi Paul👋 ,welcome to the lounge

No i wasn’t talking about your telescope. I was simply referring to FLO’s post where he stated that R&P is more suited to astrophotography whereas the Crayford is liked by visual astronomers.I’m sorry if you thought it was referring to you

What is the favored exit pupil?. I’ve heard so many opinions. The ideal i was told to aim for is 2 for DSO’s and down to as low as 0.5-1 for planets etc. Is there an upper limit over which the image will degrade? Sorry for all the questions

The only load I put on my Dobsonian focuser is the eyepiece as it’s a strictly visual affair. If I was selecting a telescope for astrophotography then I would go for the R&P design. It’s the old saying “ Horses for courses “.

Wow! Improvisation and ingenuity at their best. I love it. I’ll be thinking about this each time I wheel my own Dobsonian out for a viewing session. PS:- Is that a Baader and BST EP’s hitching a ride under the OTA?

R&P simply stands for rack and pinion and even little plastic focusers on cheap telescopes are in fact R&P focusers. Just saying

Stella Lyra Dobsonian focuser

I went for the 32mm Celestron Omni as on the Celestron website it states that due to the 1.25” barrel size the 32mm and the 40mm will show the same area of sky

I was faced with the decision on which one i should buy several months ago. On reviewing them all very closely the Stella Lyra won easily. I was delighted with the finish and solid build of the scope. The roller bearings make the azimuth movement butter smooth with a tension screw to adjust to your liking. The adjustable pivot points are a nice touch also. But the clincher was the dual speed focuser and the upright 9x50 finder , not to forget the fan for primary mirror cooling. I am so glad that I paid a few pounds more for the Stella Lyra Dobsonian 8”

I have already bought the Baader Hyperion Zoom and Barlow and been using it. I also bought a Celestron Omni 32mm just for finding targets. I use the Baader Barlow with the Hyperion Zoom but use my GSO 2.5x triplet Barlow for my other EP’s

He has fitted a Baader click lock (2”) and i thought it was only the 1.25” that fitted

Thanks Louis👍

Hi Slaine 👋 Welcome to the lounge

Was it the Baader 2” click lock that you fitted?. I was looking at doing the same thing however I thought that it was only the 1.25” that fitted due to the diagonal being 1.25”

Yes the clothes peg and jar lid mods work a treat and I used the later on my 127. I have however just found a 3D printed (glow in the dark) focus knob that just slips over the existing one, Great for the £8 posted

This thread is from 2012

Thanks for your reply and was thinking about using in my 127 Maksutov. I have just bought a Baader Hyperion Zoom and the Baader Barlow with a 32mm Celestron Omni for finding targets. I have also bought several BST Starguider eyepieces. I don’t think that the SVbony 68’s deserve the stigma attached to them.

Are we talking about the same eyepiece?

What is your opinion on these SVbony UW 68 degree eyepieces? I keep hesitating to buy one to try, but they seem to tick all the right boxes. Thanks in advance
