    The eyepiece was a 7.2mm - 21.5mm zoom used at 7.2mm with a Baader Q-Turret 2.25x barlow. The wooden tripod is of the Oberwerk hardwood type (I also have a Berlebach Uni 28 but that is generally overkill for all but the 130mm refractor). The spreader is a plastic one like the Skywatcher aluminum tripods use, but it works.

    Tripod / mount pictured below but used with the legs extended for nighttime use with the ED120.

    Thank you. It's interesting to know there are other wooden tripods (apart from surveyor) suitable for 120s. Yours looks like a TR3. 

    Did the Oberwerk have an EQ5 mounting plate?

    I was using my ED120 tonight on the Skytee II and was getting the 1 second or less vibration dampening that has been mentioned. No counterweight on the other side either. I think the wooden tripod helps :icon_biggrin:

    I got the scope up to 281x on Delta Cygni, moved the star to one side of the FoV and let it drift for periods of well over 20 seconds before needing to touch the slow motion knob. Worked nicely. The eyepiece I was using had an AFoV of 55 degrees so not a really wide one by any means.

     

     

    Which eyepiece was that John?

    Skytees that are fine are good value for money. I think their heavy weight absorbs a good deal of vibration. In a budget sense they are the almost-perfect match for 120 refractors, 8 inch Cassegrains etc. 

    Which leg spreader/tensioner do you use on your tripod?

    Have a Continuum filter. Ill let you all know how it performs day and night (the scope......not the continuum). 

    Hope it's a success! Don't let others' opinions burst your bubble. Misery loves company.

    It really depends on the target. I think X200 is a safe bet on most nights on pretty much anything, but your Tak will easily exceed X400 on a good night. The Moon, Mars, Mercury and Venus all take power well on a steady night. Jupiter and Saturn are better viewed at around X200. Obviously you'll have to match the power with the local seeing.

    I bought a 1.6 extender Q a few years ago and it was superb, but more than a bit fiddley at times. It was without a doubt the best image amplifier I've ever used, being completely transparent! However, the Tak is so good that it doesn't need the Q to reach high powers. Star images and colour correction are perfect with or without the Q in the light path, so it may save you an awful lot of money if you can try one out before buying. 

    It's mechanical things that can affect losing high power targets. Slight wobble from a mount, focuser, eyepiece or any combination. 

    I would like to go higher but find myself getting tenser trying to keep a target centered. So settle for compromise until I have had more experience maybe. 

    An extender is expensive, especially a Tak one, so will keep to Barlows for the time being.

    What is your max mag you observe with now regularly?

    About 100x on any scope Skytee mounted. Being purely hand guided that amount loses its target with even a twitch or sneeze. Dobs are steadier and I can go up to 150x on a good night. At the moment hay fever is my worst enemy.

    So with an extender I can use 13mm, 14mm to get around 100x, a better selection of what I own already. Without its just a 9mm or for the 120 Equinox a 7mm, or zooms lower end FL.

    I also prefer the 24 Pan to the ES_82 or Vixen LVW I bought, in terms of FOV performance and at the edge. 

    A slightly longer FL but very close TFOV is the 1.25" Takahashi 28mm Erfle. It has AFOV of 60 degrees is light as a Plossl and better eye relief. Also good for bino viewing.

    The Tak Erfle is "Custom" below.

    No, I don't think I need one. For planets I just use the tube as orientation. For deep sky I might just use the lowest magnification eyepiece as a finder. A Panoptic 41 gives a 4.6 degree TFOV and 14x Magnification. That is almost like a finder, but with much better aberration control and eye relief. But I'm not 100% sure about the low mag eyepieces which I should use for travel...

     

    I'm thinking about a Masuyama 45mm, which gives a 6mm pupil and should work good with filters. Maybe a 16mm Nagler for open clusters, but then I don't know which eyepiece to take between the two...

    If you want a smaller lighter 40 for travel I recommend the Vixen LVW 42mm, some of whuch FLO have in stock.

    Hi Richard @25585... the 13mm 'smoothie' Nagler I brought from you is awesome... Tnx. :thumbsup:

    I managed to get a vinyl end cap for the eye end too.

    Hi Phillip glad you still have it! Great to know you are enjoying it. Older TV eps like the 13 and my 32mm Plossl did not get eye caps. I kept them in camera lens pouches or cases, still do. 

    That 13 was my first 100x ep & was my first TV ep, fantastic for DSOs there is an 11mm smoothie Nagler on ebay, I think that was a classic too. 

  9. The red colour is too toned-up in these photos (and in the Primaluce product photos). Colour to the eye is darker, closer to Shiraz wine (or dark red apple peel) than red pepper. 

    Both my mounts have treble lock clamps on both their axis. 

    I notice this clamp is not shown in @FLO site. FLO, should you wish to add it, the SKU is below. 

    Just another dovetail bar to go.

    I've been a member of the Brandon club for quite some while. It's my second Brandon, my first Brandon was the 8mm flat top. Which put up the best views of the moon I have ever seen. The 8mm has done just as good on the planets. :)

    I have high expectations for the 12mm Brandon on the Planets. 

     

     

    I have a 48mm as does @Saganite . The Brandon is unlike any other ep I own.
