Description

TS Triplet APO 90mm Aperture - 600mm focal length - Carbon fiber tube - 2.5" TS photo focuser
... a premium quality APO refractor telescope with superb colour correction, even with full format sensors

TLapo906FT

TL APO 906 with the powerful 2,5" PHOTO focuser.

A true APO refractor with superb colour correction - premium quality - top contrast and sharpness - The TLAPO906 offers features commonly found only in much more expensive APO refractors. False colour is not only reduced - like in many other so-called "APOs" - but is virtually eliminated. You will see virtually no false colour visually and photographically. Contrast and image sharpness are on the same high level. In our opinion the TLAPO906 is a match for some of the very best APOs on the market, even those on a much higher price level.

Light, Robust, Portable - Carbon Fiber Tube - the TLAPO 906 is so compact, it can follow you anywhere! With the retractable dewcap and moderate focal length the APO is ideal for travelling. The robust carbon fiber tube reduces the weight to only 3.5kgs, despite the triplet lens objective! With the dewcap retracted the APO is only about 50cm in length.

Left picture: optional 2.5" field flattener

This flattener with 61.5mm free aperture is the perfect accessory for astro imaging. It can also be combined with our 2,5" off-axis-guider thus resulting in a superb photo machine for astro imaging!

Astro-Imaging with the TL APO 906 - one of the big strengths of this wonderful telescope! Even very bright stars will not have a false colour fringe around them. Stars are pinpoints with high contrast. Up to 15mm image circle no field flattener is needed. For large sensor CCD cameras and for DSLR cameras we recommend the use of our 2.5" field flattener. With the TS flattener you will get perfect results throughout an image circle of 54mm!

TS Optics 2.5" photo focuser for the TLAPO 906

The TS Optics focuser is a good match for this telescope. It is sturdy enough for most applications and offers a smooth focusing motion due to its integrated dual speed 1:10 microfocuser.

Via the M63 thread, the TS 2.5" flattener can be screwed directly to the foucuser using our adapter M63a-Flat25. Even heavy cameras are held precisely in position allowing long exposure times. The illuminated field has 54 mm diameter and the focuser can be rotated by 360° for perfect framing.

The Apochromatic Triplet Lens of the TLAPO 906

The new Triplet lens offers a fully apochromatic performance. Through use of high quality FPL-53 ED glass from Ohara (Japan) a very consistent quality is guaranteed.

In the spot diagram below you can see how well the TL906 is corrected!

Of course the lens is fully multi-coated for a bright and clear image.

The adujstable lens is air spaced - not cemented.

A Photographical Review of the TLAPO906:

Manfred Holocek tested this APO under real-life conditions and submitted to us a very conclusive photographical review of the telescope. Thank you very much!

Image Quality of the TS Optics TLAPO 906 - SPOT diagrams and star test:

$Spot Diagram of the Triplet APO 90/600mm refractor$

The Spot Diagram is ideal for judging the colour correction of a telescope, not only on the optical axis, but also off axis. The black rings are the airy discs. As you can see all wavelengths between 500nm and 700nm are kept inside the airy disc. Off axis (second line: 1/4°, third line: 1/2°) the colour is still very well corrected - just compare this with some very expensive APOs that might cost a lot more than the TLAPO!

$Star test of the Triplet APO 906 refractor$

The Star Test on our artificial star is equivalent to the image of a real star at a magnification around 200x. But please note that our artificial star works in autocollimation. This means that whatever optical defects there are, you will see the effects twice as strongly as on a real star!

Images from left to right:

-- far inside of focus
-- slightly inside of focus
-- a focused medium magnitude star (around 5-6 mag)
-- a focused bright star (e.g. Vega)
-- slightly outside focus
-- far outside focus

As you can see false colour is virtually nonexistent in focus. You can also see that the star is well centered. This also shows that the lens is not pinched inside its cell.

I have not been able to do photographic testen with the refractor since I don't have the flattener yet... but here are my first

observations:
This is the first budget apo I have seen which really screams! Build quality, certainly with the FT is excellent.
Startest is more than adequate for normal use, stars are tacksharp and virtually colorfree indeed. I had a look at Mars at 216x (using a TMB 5mm with TMB barlow) and boy, was I in for a surprise. Excellent contrast, color and sharpness. Not a hint of softness on the planet.

Likely 250x or even more won't be a problem. Since I put it on my wiliam optics mount, I didn't push it higher cuz no tracking.
I don't know how much Strehl it is, but I don't care, it is just very, very good.
