The TSA120/AZEQ6 arrived a while back and I was lucky enough to try it out tonight. This is just a brief report with more to come as I gain experience with this telescope. I'll get to the point here... even with Jupiter low and the seeing avg the TSA120 gave me the best view of Jupiter through a refractor so far... I can only imagine them when the planet is higher. The colors were very deep and with much detail showing in the belts and really fine shade lines through the caps were coming through.
The eyepieces used were the Zeiss 25.1-6.7/VIP barlow, 3-6 Nagler zoom and a 4mm UO ortho. The finder EP is the 42mm LVW and a Baader prism diag held the EP's.
Well, Izar can be a good test of things and the scope came through with flying colors- I love that little bright blue ball sitting on the bigger star. The optics of this refractor are good enough to show up eyepiece differences, even at this small aperture. Yup, the 3-6 Nagler got beat on Izar, with the Zeiss producing a much cleaner "tighter" look. The 3-6 zoom does do well in the color dept on Jupiter however and will stay in the collection. The Zeiss zoom also bested the 3-6NZ on Jupiter overall.
If asked to describe the look through the TSA120 I would call it "surgical" or precise, razor like. My own preference is for triplet refractors but the doublets may produce richer colors on some things- I do play around with different tone EP's and that prism diag to get the colors where I want- and they are excellent in this scope. The UO 4mm, while giving sharp views, did not give me the color tone I wanted for this set up so its out...
I like the TSA120 already, after one brief night out
ps- this scope will be killer on Saturn
As per the heads up, GRS was transiting at 6.02am this morning, so with the promise of clear skies the alarm was set.
I was too lazy to setup the AZGTi further down the garden, which would have been better, so I was stuck closer to the house and trees with the scope on the Giro-WR.
Lovely views right from the start really, GRS heading for the meridian showing some nice colour although not as dramatic as I've seen it in the past. I could see the white separation between GRS and SEB, north and south polar regions and what I assume was the South Temperate belt and Zone. Hints of a festoon dropping into the Equatorial Band.
This was another occasion when I tried cyclops first, then switched to the binoviewers to see if I preferred it. Binoviewing, on this occasion, definitely made the detail easier to access although that has not always been the case for me. I was at x230 ish and floaters were well controlled.
I thought the seeing dropped off after a while, until I defocussed and realized I was observing through the twigs of one of our trees! Amazing that I could still see some detail even then. Loppers required before the next outing I think, plus putting the other pillar extension on!
What a lovely way to start the day. Blackbird singing his heart out and the gulls floating gently overhead on their way to the reservoirs. The Parakeets had yet to start their noisy morning commute!
Two last surprises. I thought Saturn might be visible, and did catch it just before it was occulted by......my house! OK views but good just to see it again.
Finally, despite it being quite light at gone 6am, Arcturus was clear and I could also still see Izar so I popped the scope onto it. What a beautiful sight! Very well controlled faint diffraction ring around Izar and its secondary was as clear as I've seen it, lovely separation and nice almost greenish blue colour to my eye. It has always been bluish grey to me, so perhaps just a trick of the daylight. Great way to finish off, then back in for a warming cuppa and a little three year old who wanted a cuddle .
