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

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.
