Optolong L-Synergy Dual Narrowband Filter

The Optolong L-Synergy filter is designed for astrophotographers using DSLR, color CMOS, or CCD cameras who want to achieve stunning narrowband results without switching to a monochrome system. By pairing traditional dual-narrowband (Ha & OIII) concepts with a unique “Ha & OIII + SII & OIII” approach, L-Synergy overcomes the usual limitations of colour cameras and makes Hubble-Palette–style imaging accessible to everyone.

With this filter, you can produce deep, high-contrast SHO-like images of emission nebulae using your existing colour camera—no additional SHO filters or monochrome upgrade required. It’s an affordable way to achieve professional-level results even under bright suburban skies.

Why Choose the L-Synergy Filter?

The L-Synergy is a dual 7 nm narrowband filter engineered for telescopes with an f/ratio of f/3.3 or slower. Years of optical refinement have produced a design that suppresses bright star halos while delivering extremely high transmission in the key emission bands.

• Selective Narrowband Performance
  Transmits only the OIII (500.7 nm) and SII (672.4 nm) nebula emission lines, rejecting unwanted wavelengths and light pollution.

• Exceptional Contrast and Signal-to-Noise
  By isolating the oxygen and sulfur signals, the filter produces a darker background sky and dramatically improves contrast—especially valuable in heavily light-polluted environments.

• Light-Pollution Resistant
  Filters out the vast majority of urban skyglow, allowing astrophotographers to capture clean, detailed nebula structure from almost any location.

Optical Design

L-Synergy is precision-engineered based on the spectral behaviour of emission nebulae and common light-pollution sources. Its carefully tuned passbands maintain consistently high transmission in both SII and OIII, ensuring accurate colour capture and high-quality data for processing.

The result: a powerful, easy-to-use narrowband solution that unlocks deep-sky imaging performance far beyond what typical colour cameras can achieve, giving more astrophotographers access to true SHO-style imaging.

OPTEC Lepus .62x 增距镜针对镜头最后一面与图像平面之间的距离 100mm 进行了优化。从增距镜法兰测量，该距离为 105mm。假设原始焦比为 f/10，Lepus 0.62X 将使有效焦比降低至约 f/6.2。将图像平面向外移动将进一步降低焦比，但会降低图像边缘的星光质量。大多数 SCT 的最佳距离为 100mm，C9.25 EdgeHD SCT 除外。

标准版 Lepus 0.62X 远摄压缩镜头专为任何配备 TCF-S 或其他 2 英寸调焦器的望远镜而设计。可与 Meade ACF f/10 和 f/8 无彗形 SCT 望远镜完美配合使用。Lepus 0.62X 标准版装在 2 英寸筒状组件中，可装入任何用于标准 2 英寸目镜的望远镜接收器中。

Lepus 0.62X 增距镜的相机侧连接件是一种宽燕尾槽，称为 OPTEC-2100。Optec 的定制相机专用 Lepus 支架（单独提供）可保持与相机图像平面的适当后焦距。OPTEC-2100 接口还可以轻松连接到 Pyxis 2 英寸旋转器，以代替标准的 2 英寸鼻托。连接到相机后，Lepus 将显示为一个长 2 英寸鼻托，可装入任何 2 英寸调焦器或目镜接收器。

佳能和尼康相机有现货供应特殊的 DSLR 适配器，可以保持并维持 100 毫米轴上后焦距。

Lepus 可与其他望远镜设计一起使用，但不是共焦的。因此，需要重新调焦。并非所有望远镜光学设计都能保证其性能，不建议将 Lepus 与 Ritchey-Chretien 望远镜一起使用。

The James Webb Space Telescope took three decades from conception to launch but the wait has been worth it. The results of the most anticipated telescope of the 21st century have been nothing short of spectacular.

The idea for the James Webb Space Telescope (JWST) was first raised in 1989, well before the enormously successful Hubble Space Telescope was launched. The infrared telescope with a mirror larger than four meters was launched on Christmas Day 2021.

In the summer of 2022, NASA released the first scientific images from Webb to the amazement of more than 300,000 viewers who watched the event live, and hundreds of millions around the world who have viewed Webb's images since then.

Webb's Cosmos is written in the spirit of Terry Dickinson's enormously popular book Hubble's Universe, which has sold over 100,000 copies. This book contains both the classic Webb images that have already become famous and the latest images from the frontiers of science taken by Webb, some of which appear here for the first time.

Author Marcin Sawicki is a professional astronomer who is an active user of Webb's images and data. He brings a wealth of knowledge and personal experience to the book and explains the science behind the images in accurate but accessible and engaging language.

Webb's Cosmos first provides the needed historical and scientific background to understand how the telescope works and what it can do. The book then presents a curated selection of some 200 photographs with descriptive captions that narrate these images of the distant universe. Chapters include:

• Stars and gas clouds
• Galaxies both near and far
• Planets and our solar system
• Exoplanets.

AUTHOR:
Marcin Sawicki is a professional research astronomer who has been involved with the James Webb Space Telescope Project for more than two decades and is now extensively using Webb for research. He is the co-author of 20 research papers based on data taken with Webb. A professional educator and experienced science communicator, Sawicki is Professor of Astronomy and Physics at Saint Mary's University and has held prestigious appointments: Canada Research Chair, Canadian Space Agency Science Fellow and Plaskett Fellow.
