DayStar T Scanner upgrade to ION housing
The promise :
- Reuse my old T-Scanner 0.5°A etalon
- Benefit of ION housing with temperature regulation
- Keep the 30mm Clear Aperture of my T-Scanner
The unbelievable : It cost 900$.
The result is astonished : state of the art Solar filter !
New housing with power input
Still 0.5°A 
Thermo control
Heat disperser
2 fans integrated
New ION housing
Clear Aperture : Still 30mm

Reused of my old T-Scanner Pelican case

H-Alpha Setup - Equipment
Takahashi FSQ 106
Astrophysics Mach One mount
110mm Baader D-Erf + 110mm Iris
Takahashi FSQ x1.6 barlow
Televue x4 powermate
x2 ED barlow
William Optics 1/20 Diagonal
Antares x0.7 focal reducer
Pentax 40mm XW
Binos : MarkIV & Denk II & Siebert 25mm
Pair of 24mm Pano & 30-40mm Ploss

x1.5 factor if the barlow lens is screw in
front of the eyepiece.
So with a powermate :
x4-> x6
x2 -> x3
Iris reduction – A must have
Help to get F30 ratio at lower focal
Change the bandwidh of the Daystar filter in a second !
If full aperture at F20 the Daystar 0.5A is acting as a 0.8A!
The result : proms a even greater !
Taka x1.6 extender
The issue : No ring !
With the weight of the bino
head, it rotates and
damages the diagonal nose!
The solution: Drill a few the
nose of the diagonal so one
screw can fit inside.
It rocks! : no more move at all.
H-Alpha – Eyepiece setup
Eyepiece Usual Setup – Full Aperture
F5 refractor + x1.6 Taka + x4 powermate = F32
x1.6 Taka is optional with Iris reduction
The short Televue SCT->2’ could be replaced by a long one.
Eyepiece Compact Setup – Full Aperture
F5 refractor + x1.5 ED barlow + x4 powermate + x0.7 focal reducer =
F21 refractor
Into focuser of F5 refractor

H-Alpha – Bino setup – Mark IV
Bino setup – MarkIV – Standard setup
x4 = F20 – Mark IV – 24mm or 40mm
x1.6 + Diagonal + x4 = F32 – Mark IV – Best with 40mm
Bino setup – MarkV + x0.7 Reducer
x1.6 + x4 + x0.7 = F23 – Mark IV – 24mm or 40mm
Bino setup – MarkV + x0.7 Reducer
x1.6 + x4 + x0.7 = F23 – MarkV – 40mm or 24mm
-Full disk with 40mm & 24mm
just inside FOV.
-Proms visible arround. Some
are faint/dimmed due to
-Spicule visible
-Fine Surface details
-Filter uniformity limitations.
- Soft zone at 80% of FOV.
x4 barlow + x0.7 = F14 – MarkV – 24mm or 40mm
-Full aperture :
-Great view of proms all arround
-Reduced Iris :
-Better surface details
-Most of the proms still visible.
-Spicule better visible
-- Soft zone at 80% of FOV.
H-Alpha – Bino setup – Denk II
Bino setup – Denk II – Standard setup
x4 = F20 – Denk II – 24mm or 40mm
X1.6 Taka extender can be added in front of the diagonal.
Bino setup – Denk II+ x0.7 Reducer ?
x4 + x0.7 + x0.7 = FD10 (F 1040mm) – Denk II – Only with 40mm Ploss T
DenkII with short nose – Cut by myself
Bino setup – Denk II+ x0.7 Reducer ?
x4 + x0.7 + 0x7 = FD10 (F 1040mm) – Denk II – only 40mm Ploss T
- Soft zone at 70% of FOV.
Full disk with double x0.7
smaller enough to be inside
the clear zone.
- Fine details (Proms+surface)
-Eyepiece relief shorter
(16mm?) : More confortable !
-Focus with the 3
powerswitch position!
x4 + x0.7 + 0x7 = FD10 (F 1040mm) – Denk II + short nose.
-Better view
-More stable/compact setup
-Focus ok
-Soft zone area reduced
H-Alpha – PST Setup
Siebert 25mm bino + x1.8 Siebert OCS + 30mm NPL Ploss.
PST extension tube removed to get focus.
Default 5mm blocking filter used.
Thanks to the great Siebert OCS : Very comfortable view, no
Shadow, “wide” view.
Great full disk view.
