The Omegon RC telescope for astrophotographers.


Are you looking for an excellent telescope for astrophotography? Omegon Ritchey-Chretien telescopes will take you to the next quality level with your astronomy photos. Omegon RC telescopes provide a wide, coma-free field of view - perfect for round stellar images right out to the edge of the field of view. Find out exactly why an RC telescope is the right choice for astronomy photography and why the professionals also use them.

The advantages in a nutshell

  • hyperbolic mirrors - extremely sharp image, wide field of view, with no need for a corrector
  • BK7 mirrors for stable focus
  • high reflection - 92-94% dielectric reflective coating for bright, high-contrast observing and astronomy photos
  • rapid cool-down thanks to open design
  • electric fans for even faster cool-down (only for 10" model)

Steel OTA for stable focusing and high contrast
In addition to containing a good mirror, a steel OTA plays a decisive role in producing good astronomy photos. This Omegon RC OTA has a 50% reduced focus shift when compared to an aluminium OTA. Precisely located stray-light baffles also ensure high contrast


Now affordable
Making hyperbolic mirrors is both a science and an art. Up to only a few years ago, RC telescopes were among the most expensive telescopes in the world - only international institutions used them for research. But this technology is also now also affordable for experienced amateur astronomers.

Optics

A better image than an SC telescope
To start with, an RC telescope is completely different to the classic SC or Maksutov design. It has no corrector plate and is hence an open system that adapts faster to the ambient temperature than an SC telescope. The absence of a front corrector plate also means that the telescope provides brighter images with no risk of internal reflections. Ritchey-Chretien systems are the most highly corrected two-mirror telescopes available. Their edge-to-edge image sharpness is impressive, so it is no wonder that practically all large research telescopes use this design of telescope in their professional observatories.

Hyperbolic mirrors for a better image
RC telescopes have hyperbolic main and secondary mirrors. They do not use spherical mirrors, such as in Schmidt-Cassegrain systems. This great idea gives you a big advantage - take better and sharper astronomy photos and enjoy a wider usable field of view! Ultra-sharp with APS-C chips. even without using a corrector. This technology was unaffordable even a few years ago, but the new Omegon RC telescopes are now affordable for every amateur astronomer.

Photograph without needing a corrector
Use your DSLR or astronomy camera with your telescope without needing a corrector, for coma-free and pin-sharp stellar images, right out to the edge of the field of view. The 8" and 10" models even allow you to use 24x36mm full-frame chips without any corrector. All professional DSLR cameras will fit and countless astronomy cameras too. And, if you still want to photograph in the medium format, please do not hesitate to ask us for appropriate solutions.

Good shelves
Item Package Quantity: 1, Size: 6 Tiers
Unit was pretty easy to assemble. Shelves are sturdy and no scratches or dings. My only complaint is that there is paint missing here and there on the black pipe. We covered those spots with magic marker. I would buy it again!

An excellent collection of essays
Format: Paperback
An excellent collection of essays. A few of which deserve a brief note. As someone from within the Reformed tradition, I particularly appreciated the chapters on Calvin and the missional impulse of the Reformed branch of the Reformation (Chapters 4, 5, and 6). Karen Spiecker Stetina’s chapter on Calvin’s Geneva as a virtual mission training center to launch missionaries around Europe and elsewhere was not only enlightening but instructive. The chapter detailing the Reformed mission to Brazil (chapter 6)–while the mission itself was underwhelming in its achievements–was especially intriguing. These chapters thoroughly undue the misconception of Calvin and his followers as missionally indifferent. Turning to the Catholic portion of the essays (the book is split into two portions, one detailing Protestant mission in the 16th century, and the other, Catholic mission during that period), one will find essays dealing with spirituality surrounding missions (chapters 10 and 13), the intersection of missions and colonialism (chapters 12, 14, and 15), and the issue of accommodation in mission (chapter 11). All of which are exceptional. As someone who has spent time practicing and studying mission on the continent of Africa, I found John Thornton’s chapter on the Jesuit mission to Kongo in this section to be particularly insightful. This is partly due to the nature of the mission itself. As Thornton points out, the mission was not to evangelize but to “reform a new but vibrant Catholic Church” in Kongo (265). This chapter has much to teach contemporary mission practitioners in Subsaharan Africa as the situation is largely the same for missionaries there today: one of building up rather than evangelizing. What’s more the mission failed after only a 7 year stent. There is much here for missionaries to evangelized lands/peoples today to sit with and learn from. But perhaps the greatest benefit of the book is an expansion of an understanding of mission. Rather than viewing mission narrowly as moving to a foreign land, the essays (particularly in the Protestant section of the book), as Smither notes in the introduction, “allow Luther, Calvin, Ignatius of Loyola, Teresa of Avila, and others to define mission on their terms and through their practice” (1). One must read the book to come a full scope of how they did so; but it ranges from being light in dark places through the preaching of the true Gospel, to church planting, to the creation of training centers just to name a few (and those are just from a single chapter!). Gallagher and Smither’s Sixteenth Century Mission is an excellent contribution to the study of Christian world missions especially as it deals with an era typically thought to be devoid of what we today understand that phrase to entail. Disclaimer: I received this book for free from Lexham Press in exchange for an honest and thorough review. I was not required to write a positive review

Somewhat niche but a treasure-trove nonetheless!
Format: Paperback
A somewhat niche topic but a small treasure-trove of a book nonetheless! Definitely something I would recommend to anyone thinking seriously about and planning on studying mission. More than just a descriptive history book, the various essays focus on what can be drawn and learned from particular figures and movements. I picked the book because I knew next to nothing about 16th century missions (and not very much about Protestant or Roman Catholic missions in general) and thought it would be good to fill in some of my knowledge gaps. I was not disappointed! There are essays on people I never even heard of before, and now wish I could know so much more! Who knew there was a Czech theologian (Jan Hus) who wrote a devotional for women in the early 1400s? I certainly didn’t. Also, the very first essay I found to be a healthy challenge to Gustav Warnack’s conceptualization of mission (that ...“it must be a systematic work, preferable by an institution outside the church that consistently sends missionaries to previously unevangelized areas.” (p.12)) and his critique of early Reformation missional work (namely that there was none). Plus, while I had heard that Calvin had sent some missionaries to Brazil, I never knew there was so much drama with Villegagnon behind it all! The whole ordeal and everything leading up to it sounds like it would make for pretty crazy reality show or a great movie. The book touches on missions to a variety of locations, Kongo, China, Brazil, Latin America, and Europe itself, and is especially helpful in understanding the origins and philosophies of Reformed, Anabaptist, Jesuit, and Franciscan missiologies. It also gives light to the many complexities of mission work, dealing with politics, economy, culture, competing religion, and language barriers. Not all of the essays are created equal but I definitely got something from each one. Also, as a small disclaimer, the book may be a bit more of a laborious read for some. It deals with a great many events, places, and names that may be unfamiliar to someone not studied in Christian missional work (like myself). But working through such things can yield some ripe fruit. Being a collection of essays around a particular topic, it is a great book to pick up and set down again, not requiring large chunks of time to work through. In fact, it may be better read in several small intervals, one chapter per sitting, to properly digest each essays significance. I received this book for free from Lexham Press in exchange for an honest review, whether negative or positive. The views of this expressed in this review are entirely my own.
