That is true. According to Texas Nautical Repair, there are a couple of them left unsold. 

Nice bino-scope opportunity then smile.gif

Thanks for the very useful opinions. Acrtually I have a chance to look through Tak 100DC in February this year but wasn't impressed, maybe it was a bad sample, it was also dim and not sharper than 120ed. Actiually my skaywatcher 120ed was alot brighter at 300x with more contrast and a tinty bit sharper and holds better high power viewing. So I hope 100dl or fs102 to be better than 100dc, at least with more sharpness, contrast and brighter image.

I'm not surprised the 120 gave a brighter image as it has quite a marked increase in aperture. But lets be honest, the 120ED is an incredible scope in its own right. A few years ago I'd been loaned an 8" Dob by a friend. I'd left the Dob and my Equinox 120ED set up in the garden from around 3pm so each would be thermally stable. It wasn't until around 9.30pm that me along with a friend looked through the scopes. I first aimed the 8" scope at the Moon. It was superb, and I thought the 120ED would struggle to compete. But on turning the 120 on the Moon, the view was so much sharper. I then turned the 8" Dob  onto Saturn, and again the view was outstanding. Again I thought the 120ED had little chance of competing, but turning the 120 onto Saturn it simply blew the 8" out of the water. The ultra fine detail both in the rings and on the globe that was easily visible in the 120ED was lost in the 8" reflector.

Around the same time a friend brought his Tak TSA 120 to play alongside my Equinox 120ED. I looked through the TSA and easily convinced myself that the 120ED was almost equal in performance. I was of course deluding myself. The TSA was in reality in a whole different league, but for general observation the initial impression is very similar. Then in 2015 I bought a FC100DC. On the first night while viewing Jupiter with both scopes alongside eachother, the 120ED gave a very pleasing view. This was the same scope that destroyed the 8" reflector. But when I looked through the FC100DC at Jupiter, it took my breath away. The definition in the DC left the 120ED behind even at only 180X. Granted, the 120 was brighter, but the DC had superior definition by quite a noticeable margin. I'd owned the 120ED for around 8 years and it was a great scope which served me well, but it had met its match with the FC100DC.

The DC never once failed to impress me with its ability. Over its five years with me, I can honestly say it showed me more than anyother scope I've ever owned. It's lunar and planetary performance was outstanding. At 300X on the Moon the DC was just getting warmed up. It would coast along at 370X  and even at 463X with a 1.6mm Vixen HR it was in the zone. I've owned some great scopes, even the awesome FS152, but the FC100DC was my all time favourite. Even its Deep sky performance was amazing when the sky was transparent. 

Tak don't make bad scopes, but I can see how some might initially think the smaller aperture FC isn't as good as the 120ED,  but over several nights of good seeing, I'd be certain the DC would prove its worth.

 

My 120ED was a terrific scope. A great all round refractor.

My FC100DC was the best scope I've ever owned to date.

Many thanks for the great post and detailed comparson! 

It seems to me that i look through a bad sample of DC with average sharpness and low contrast because on Jupiter my 120ed was definitely more contraster.

Remember that the SW120ED has a great reputation for having quality optics.  There are some really good refractors out there besides the ones that Takahashi makes.  Also, the 20mm of additional aperture is a bit of a game changer too.  There are many observers out there that would love to go from a 120 to a 140 because they know what a difference 20mm can make.  And I am not dissing Taks.  I own one myself.

I can agree with mikeDknight. Comparing my 120 Equinox with my DL Tak, magnifications need to go high to see any difference. Those 120s are really fantastic value optically, Equinoxes like Orion Eons were the deluxe versions making a great product better still.

 

120 v 120, TSA v S-W, its even harder for visual. While the Equinox can have a smidgeon of CA, the TSA has none I have seen. Teeny detail can be seen better at high mags in the TSA, there is more contrast, not a lot and side by side viewing, going between each, identical eyepieces, diagonals, shows the differences. For a doublet 120 my Equinox is fairly heavy, for a triplet my TSA is reasonably light, they balance well & I can use a Skytee 2 or Giro Ercole with each without overload risk, but they are both at both mounts' max limit with mounting hardware, finder & optics.

 

DZs on such mounts will be no problem, my DL & 100 Equinox ride fine, DL being lighter weight. 

 

 

 

Where both my Taks score best is low, slightly lit skies. High viewing is easy & rewarding for most scopes, but the best can give good views under more demanding skies.

Back when I got my SW120ED, it was $1499. It is now $1925, which is almost as much as a FC100DC or DF. Many more will go for the Tak option now, I suspect.

HERE is a link to a preliminary review. The reviewer has a lot of experience reviewing telescopes and refractors.

 

Scroll down to the Tak DZ review.

 

The site has more extensive reviews of the FS, TSA, DL and DC versions as well. And there is a whole article on 4" refractors.

Excellent read. "..bless their little fluorite blanks" waytogo.gif bow.gif  .

 

My 900mm DL lets me use longer FL eyepieces, & so still has that advantage over a DZ. If a conversion kit was made for DC, DF & DL to retractable dew shield I would buy one.

 

Shame the Vixen AX103S was not reviewed, its the TSA102 slot successor, a long FL Japanese triplet, with a field flattener & retractable dewshield.

Thanks for the link. I like his reviews, clear and honest!

 

In the end note of the excellent read, he writes:

 

"

So far, my the DZ appears very impressive – effectively false colour free and very similar to the FS-102.

The trouble with that statement is that its made from memory. My memory of the FS 102, is that it showed more CA than the any of the new FC100D series. However, I did use a number of Naglers back then, which are not the best eyepieces if you're judging CA. The DL is without any doubt better corrected than any FS, so the DZ has to be better too. As for the DC/DF, they are at least as well corrected visually, but sticking my neck out, I'd say they too, though warmer in tone, are better corrected for CA. But the only way to know for sure is to do a side by side compare on a top class night& from the same site with the same experienced observers, and same eyepieces & prisms/diagonal.

I will probably sell my FS102 to help pay for the DZ. However, I want to do some comparisons between the two before I do. The DZ should be better, but I want to confirm that to myself. I had to declare to my wife that the DZ would be the last telescope that I would ever buy. So it had better be a great one!

Mike, I have done side by side test between FS102NSV and FC100DF. The FS102NSV is better corrected then FC100DF for sure, at least the sample that I have of FS102NSV. I have tested with same diagonal and eyepieces. Used Pentax XO 5 and 2.5mm, Vixen HR, Tak LE, Pentax XW. The FS102NSV can take higher magnification then the FC100DF. I had two samples, FC100DF and FC100DC. The DL is color corrected as it gets, better then FS and FC100DF. I do value the reports of Roger Vine, Daniels and of course yours. But we will never know how your FC100DC would have performed against the FC100DZ as you have already sold the DC. I would have loved to know your findings.

I think I've used that excuse with every telescope I've ever owned. "This will be the last one I'll ever need, honest!" I've told her repeatedly. The DZ may be the one that slips under her radar, as I'm hoping she won't notice the difference. I'll report back if I get away with it!  brick.gif

Is that frost on those telescope tubes?

I'm blaming Daniel M for my turmoil. There is a DC in the next town, so I can invite its owner to the DC, TSA, DZ compare later in the year. I'm thinking around the time of the Perseids in August, as in my mind that's the start of a new astro season with the dark nights beginning to draw in. I've already invited Roger and he's accepted. Should be a good night! bigshock.gif

 

I've attached my last sketch made with the DC. No idea why its on its side! I'm really missing it, and my DZ won't arrive u ntill around the 20th.
