What are the pros and cons.

. I have some background in making my. It lives on a pier on my back deck. A special corrector is placed just before focus.

Page 1 of 7 - Making a 145 Harmer Wynne Cassegrain - posted in ATM Optics and DIY Forum. For CCD use with the SARA acquisition assembly the secondary mirror had to be moved substantially forward 60mm compared to the original speciﬁcations for wide-ﬁeld photographic plates while retaining. The original optical design is shown by Harmer.

The TI 35 offers a very compact light-weight high-end performance astrograph in super-fast f35 1230 mm of. I only have a zone of about 30 degrees visibility due to overhead trees so I have to be patient year-round to wait for. The Harmer-Wynne HW design was originally published by two professional opticians in 1976.

The telescope is a Cassegrain reﬂector based on the Harmer-Wynne optical design which uses a parabolic primary mirror spherical secondary mirror and a doublet lens to correct the comatic aberration and astigmatism introduced by the mirror pair 11. The Imaging Dall Kirkham Convergent Series and Imaging Harmer Wynne telescopes provide flat field image circles of 40 50mm diameter. The system is made by an aspherical primary mirror aspherical secondary mirror and a lens group in the back.

Once Officina Stellare decided they would make this dream telescope a reality they put Italian optical designer Massimo Riccardi on the job. AG Optical Systems telescopes are designed to provide a highly-corrected flat imaging circle suitable for demanding astronomical CCD imaging applications. The design which is a modification of the Harmer-Wynne has an aspherical primary and a spherical secondary.

Hello fellow ATMers I am starting this thread to log my progress with a 145 Harmer Wynne Cassegrain design using an AG Optical carbon fiber tube. Does anyone have experience with such optical design. This short nail design has a bit of a vintage vibe and It really is Tremendous feminine.

This nowdays new optical design comes from a modification of the Harmer-Wynne scheme. Flat-field Harmer-Wynne optical design. Optical layout of a Harmer-Wynne telescope.

70mm 16 diffraction-limited image circle. We have chosen the best optical configurations and the best glasses to reach the TOP even with the very fast models up to the fantastic value of f26. Polka dots vintage flowers and a gorgeous blue hue set this nail art design excessive.

Using a HarmerWynne optical design a flat and achromatic focal plane of 100 mm x 100 mm is created with an exceptionally stable point-spread function. The RiFAst series uses a aspherical primary and spherical secondary which is a modification of the Harmer-Wynne design. Harmer-Wynne optical design which is similar to a Dall-Kirkheim parabolic primary spherical secondary and corrector lenses.

Its on a Paramount MyT mount. Once Officina Stellare decided they would make this dream telescope a reality they put Italian optical designer Massimo Riccardi on the job. Optical miscellany Telecentric low distortion 2.

Harmer wynne optical design To apply simply stick on the nails we like to maintain them at the base of our nail beds and set with crystal clear topcoatA watch-catching style has never been less complicated. The Harmer-Wynne design employs a parabolic primary mirror spherical secondary mirror and two-element afocal corrector lens located in the primary baffle tube. I am in the market for such type scope and so far I was contemplating the Planewave CDK 125.

The RiFAst series uses a aspherical primary and spherical secondary which is a modification of the Harmer-Wynne design. The TI 35 350 mm of clear aperture is based on the same Modified Harmer Wynne optical configuration as Telescopi Italianis TI35 f5 system. The RiLA is corrected in the visible-near IR range with more than 80 of energy focused in 4-6 microns RMS spot.

Only one professional telescope of the design was made but it occurred to us at Starizona that the design was ideal for an amateur telescope. The result is a flat field free from coma and astigmatism. I purchased the CF tube from AGO a few weeks ago and it came with no optics.

Top-Notch Optical Design for best performances Each of our telescopes has been designed and optimized to achieve the highest optical performance ever seen. Optical design and facilities Our TI 35 both models TI 45 f4 and f52 TI 55 f35 and f49 and TI 65 f35 and f47 Astrograph are derived from the configuration Harmer-Wynne designed for the first time and published in 1976 Royal Astronomical Society Monthly Notices vol. A Simple Wide-Field Cassegrain Telescope articleHarmer1976ASW titleA Simple Wide-Field Cassegrain Telescope authorCharles F.

The telescope is equipped with a focal reducer that converts the focal ratio from. It is 19 x. DESIGN CONSIDERATIONS The design for this 3-element corrector derives from the 2-element Harmer-Wynne corrector2 developed for the Jacobus Kapteyn Telescope JKT a 1-m telescope with a 15 field of view located on La Palma.
