Lunt HAlpha Solar Filter Systems

The first three products under this category are Double Stack Etalon Solar Filters that are to be used with H-alpha filters or H-alpha telescopes to increase their contrast and detail by reducing bandwidth.
The rest of the products are H-alpha Filters that are designed to retrofit your astronomical telescope for observing the sun during the day. Several filter sizes can be matched with an adapter-plate to the existing scope aperture. Systems include front mounted Etalon filter and the required rear mounted 50.8 mm (2") or 31.7 mm (1.25") blocking filter. There are many more available sizes, but it'll take some time until we list them all, so in the meantime please contact us if you cannot find the one that you need.

A quick message for those who might have thought to miss this promotion is that due to the fact that 1 Jan was a bank holiday followed by a weekend, we decided to end it on the morning on the first working day of the year: 9am on Monday, 4 January 2021.

So from now you will still have about 36-37 hours to make a decision... The following camera are in this promotion:

ASI071MC-PRO (APS-C sized),

ASI6200MC-PRO (full frame) ASI6200MM-PRO (full frame) and various bundles with this monochrome camera,

ASi2400MC-PRO (full frame, large pixels),

ASI1600GT (with built-in filter wheel),

ASI183GT (with built-in filter wheel),

ASI2600MC-PRO (APS-C sized) (one of the most popular cameras these days),

ASI533MC-PRO (smaller square filter, but extremely popular) ASI1600MMP-KIT3 (this is the only camera that will stay on promotion till stocks last),

ASI462MC-PRO (currently the best and most popular planetary camera due to its extreme sensitivity in near IR),

ASI120MC-S and ASI120MM-S (no introduction needed - our longest selling planetary imagers and guide cameras),

and finally but not lastly at all: ASIAIR PRO (and BUNDLES) - the must have all rounder astro photographer's brain and power center for your ZWO camera: for aligning, locating, guiding and imaging, etc. - all in one...

Hope you can find something on the above list that might be worth considering!

Happy New Year!

Zoltan and the Team

Baader 2" BDS-RT Diamond Steeltrack RT Focuser for Refractor Telescopes
Baader 2" BDS-RT Diamond Steeltrack RT Focuser for Refractor Telescopes
Fitting a 2-inch BDS-RT Baader Diamond Steeltrack Focuser to a Teleskop-Service GSO 8-inch Ritchey-Chretien Background The TS 8-inch RC has M90x1mm connections at the focuser end of the scope. My setup has a TS 50mm extension adapter with for 6- & 8-inch RC connected to the scope (TS part no: GSRCV50), to accommodate the long back-focus. Attached to this is a TS M90 tilting adapter flange (TS part no: GSRCJ90). This is an aid to collimation and allows the long axis of the focuser to be aligned with the optical axis of the scope. I then have a standard TS monorail focuser for the RC, again with an M90x1 connection. Image 1 shows the 50mm extension and tilting flange, with the old focuser removed. Note the M90 male thread at the end of the flange, to which the focuser connects. Fitting the Baader Diamond Steeltrack RT It is assumed that the reader has access to the Steeltrack manual and has purchased the necessary RT-Adapter M90x1 Diamond Steeltrack (Baader part nu...
