• New Splash with alpha blending added
•  Icons for the "Design Manager", "Lens Calculator" and "Design Wizard" in the Toolbar (speedbar)

•  Lens Calculation added - available from "Tools" menu. The freeware release has some restrictions by using this function.

• Multiple "PDF Report"
• Multiple "PDF Viewer"
• "Look" from Graphical and Text windows - available from the local window menu
• 2D, 3D-Optical Layout - supported drawing of automatic, fixed and pickup heights (see surface editor "solve heights")
• 3D-Optical Layout - stops are drawing as circles

• Easy Telescope Design

1. Cassegrain baffling calculation for Cassegrain like systems added - Cassegrain, Ritchey-Chretien, Dall-Kirkham, Pressman-Camichel (see the layout bellow). The white slope shows that the calculation is exact, i.e. the upper edge of front shield, rear shield and bottom side of the field edge lie on the white slop.
2. Automatically generated design description that includes design clear aperture and focal ratio.

• Surface Editor

1. Undo function to the "Edit" menu - if inserted or deleted surface
2. Undo function to the "Surface Type" popup menu - if surface type is changed
3. Solve Heights - Automatic, Fixed and Pickup in conjunction with 2D and 3D optical layout. How it work: If "Automatic" is selected the heights are calculated by MODAS and all rays at field edge are transmitted. This is useful for calculation of the heights for the maximal field of view. If "Fixed" is selected the optical layout use fixed heights to show the effect of vignetting, i.e. not all rays are transmitted. Useful for example by exploring cassegrain light shields (baffles) or central obstruction. If "Pickup" selected, the drawing surface become his value from selected surface in the "Solve Heights Dialog". Useful for exploring of Mangin mirrors or Klevtsov telescope etc.
4. Print and PrintPreview of the surface spreadsheet
5. HTML-Preview of the surface spreadsheet

 

• New Design - if new design is created and saved as "NONAME.DSG", the inserting to the file history is not correct i.e. the path to the file is missing and cannot be viewed (developer fix).

1. Schmidt-Camera, Schmidt-Cassegrain - if you have entered "Corrector Diameter" with ending different 0 or  5, for example 202 mm, by pressing "Report" button MODAS cannot exit from the loop that calculate the corrector profile (reported by Grant Christie).
2. Telescope Layout - if uses "Copy to Clipboard" or "Save Graphic As" functions after executing, the picture is loss (developer fix).
3. Calculation of Gregorian secondary clear diameter (reported by M.Gobato)
4. Floating Point error by designs with lenses (excepted One-, Two- Mirror and Stevick-Paul designs), i.e appear if currently open some existing design and new design is performed by using "Easy Telescope Design"

• Surface Editor - the surface editor seems to change surfaces randomly - some become aperture stops, their radius gets set to zero, the material disappears (reported by Bruce Dickson).
• Options|Show System Data - Windows error if closed "System Data Settings" dialog (reported by Grant Christie)
