Gerd Neumann Deluxe Flatfield Foils

Gerd Neumann Deluxe Flatfield Foils

The deluze flatfield foil come in a square size for instruments of various sizes. The frame is made of unbreakable polymer with a special protection around the edge. The opaque frame gives you an even more uniform brightness than using a foil alone. In addition the foil is very well protected against humidity and moisture and dirt and scratches during transport.

For very fast system you will have to reduce the brightness by placing (some) sheets of paper in front of the foil: The DX frame also holds this in place very well.

The EF DX Flatfield Foils give you the ideal and pratical flatfield-source for even the most critical applications!

Color
The light from the foil looks blueish/white. Most foils from other sources seem to be white to the human eye, but the light is made of discrete emission lines. -Due to this the foils from most other sources at not suitable for narrowband emission line filters! Gerd Neumann tested the products of all manufacturers worldwide and selected these foils because he feels they are the best for astronomical applications!

The spectrum of the EF is not made of some emission lines (like most foils). It has a very broad, continuous emission across the whole spectrum. This fact makes the foils great for narrowband emission line filters.

Gerd Neumann Ronchi Eyepiece

Gerd Neumann Ronchi Eyepiece

This handy new accesory will help you to check the quality of most telescopes.

Although all abberations of an optic can be seen in a Star Test,this requires very steady air and lots of experience.

Compared to the Start Test the Ronchi Test works well with medium quality seeing and also it will be easier for a beginner to perform a correct analysis of the telescope after a short period of learning!

Included in the package.

The Ronchi Eyepiece consits of a mainbody made of black anodized aluminium with an 1,25" shaft.

Some Gratings from other manufacturers are made of exposed film or laser printouts: Those gratings will show inferior contrast and will be much more difficult to analyse! This Ronchi eyepiece is equiped with a vacuum metalized chrome on glass grating with 10 lines per millimeter. The grating is on the telescope side of the glass and is exactly in the same plane as the outer stop.

The Ronchi Eyepiece is shipped in an protective housing with a short manual in English.

ATIK Instruments

ATIK Off Axis Guider

ATIK Off Axis Guider

As a complement to the filter wheel, we also developed an Off]Axis Guider, which
features just about everything needed to successfully use this kind of guiding system.
It features a moving prism which allows
selecting the best quality stars of your
corrected field of view, while maintaining
the possibility of using from small VGA
sensors up to 35mm multi megapixel full
frame beasts.
It also features an extremely smooth and
precise fine focus system, with extension
rings of 3 different lengths, so that
different types of cameras reach focus
with different types of autoguiders.
The OAG interfaces perfectly with the EFW2, meaning that no spacing exists between
both units, keeping total backfocus requirements low.

IKI 80mm F7 Achromatic Guidescope

IKI 80mm F7 Achromatic Guidescope

Here is an 80mm F7 decent quality achromatic refractor that with the addition of the included 30mm extender works superbly as a guide scope.

The scope features a decent 1.25" rack and pinnion focuser that can be locked and easily provides more than enough rigidity for any of the autoguiders commonly available.

The scope features a decent quality sharp 80mm F7 achromatic lens that also provdes surprisingly good performance for visual use as well.

There is a sliding retractable dew shield and decent quality finish on this scope.

TS

TS Universal Refractor Field Flattener

TS Universal Refractor Field Flattener

TS 2" Field Flattener - Universal Field Flattening Lens

This revolutionary new field flattening system is the first one to our knowledge that offers a superior quality compared with conventional systems:

-- larger possible illuminated field through elimination of the "T2 keyhole". The flattener has 45mm clear aperture compared with 37mm for typical T2 adaptations.
-- excellent performance on a broad range of very different refractor telescopes from f/5 to f/8.
-- very large Back Focus distance from 100mm to 110mm (depending on the telescope). This allows you to attach extra accessories between the camera and the flattener, like off-axis guiders, filter quick changers, ...
-- a multitude of different adaptations is possible. The flattener uses the standard 2" filter thread
-- visual use is also possible with the 2" filter thread adaptation - just screw the flattener into the 2" barrel of the star diagonal mirror - this will improve image sharpness towards the edge even for photographic use.
Practical Applications:

The left image shows a typical setup of the field flattener with f/6 to f/7.5 refractors and a digital SLR camera.

-- The flattener is on the far left. It disappears completely inside the focuser.

-- Next to the flattener is an M48 extension tube to get the proper distance. The extension tube is available in several different lengths.

-- In this case the camera adaptation is through the conventional T2 thread via a T2 bayonet ring. For Canon EOS a separate adaptation is also available with a larger clear aperture.

Specifications:

-- field flattener with blackened lens edges. Multi-coated.
-- no focal reducer function!
-- thread on the telescope side: M48 (2" filter thread) female
-- thread on the camera side: M48 (2" filter thread) male
-- clear aperture 45mm (much larger than with conventional T2 systems)
-- the flattener disappears completely inside the focuser. It does not inherently require any extra back focus.

Recommended distances between the M48 thread of the flattener and the sensor of the camera:

-- Achromatic refractor f/5 ............... 100mm to 105mm
-- Refractor f/6.6 ............................. 103mm to 109mm
-- Refractor f/7.5 ............................. 105mm to 110mm

Practical experience has demonstrated that the flattener has a large tolerance for deviations from the ideal distance. 5% deviation does not cause any deterioration of the image quality in an APS-sized sensor (DSLR). For smaller sensors (CCD) somewhat larger deviations may be acceptable, but please keep in mind the higher resolution of many CCD cameras which in turn suggests that the distance should be kept as precisely as possible. The main tests have been made with a Digital SLR camera with a 15.1mm x 22.7mm sensor.

Includes the following
-- 2" barrel extensions
-- 2" on T2 adapter with 39mm length

Warren Keller IP4AP- Image Processing For Astrophotography
IP4AP was created for Astrophotographers of all skill levels. There are many resources for learning Image Processing, but we believe these techniques are best taught - Visually! Let "Image Processing for Astrophotography" be your guide to the easy and fun way to learn the most sought after techniques in Astro-Imaging.

Unleash the power of Adobe Photoshop on your Astro-Images! You've made a large investment in equipment - Now make a small one and learn the secrets of producing stunning Astrophotographs. IP4AP has produced three series of quality videos called Photoshop Foundations Basics, Photoshop Foundations Intermediate Part-1 and Part-2 The Five Ss. They'll convince you.... Visual learning is the easy and fun way to go!

If you've ever been dazed and confused at the thought of doing Astro-Imaging and Processing, don't be! Everyone learns differently - Some people are great at reading instructions, others learn through trial and error, and many learn best by being able to actually "see" how something is done. That's the secret behind IP4AP’s "Image Processing For Astrophotography". Let's take a look at how the system works...

Photoshop Foundations Basics - This is where to begin! Adobe Photoshop Basics walks you through Photoshop step-by-step, with an emphasis on Astrophotography.
