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
Heat disperser 2 fans integrated
Thermo control
New ION housing
Clear Aperture : Still 30mm
Front
Rear
Reused of my old T-Scanner Pelican case
12V, 1.5A power supply
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
H-Alpha Setup
2x ED Barlow lens
Barlow lens 37mm Clear Aperture
2’’ eyepiece holder Spacer Reducer
x1.5 factor if the barlow lens is screw in front of the eyepiece. So with a powermate : x4-> x6 x2 -> x3
M48 M50
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
ED barlow used as x1.5 barlow
Powermate x4 + T2 adapter
Daystar filter With SC thread rear plate
SC Female to M48 male adapter
William Optics Diagonal, with nose removed
2’’ x0.7 or x0.5 focal reducer
Pentax XW 40mm
Eyepiece Compact Setup – Full Aperture
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
x4 barlow + x0.7 = F14 – MarkV – 24mm or 40mm
-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.
-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
x4 + x0.7 + 0x7 = FD10 (F 1040mm) – Denk II + short nose.
- 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!
-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.
