Laser Colli


Baader Planetarium has added a unique innovation to the laser collimator.  The Laser Colli incorporates a viewable etched viewing plate which can be seen through the back of the laser collimator.  This permits collimation of  SCTs and small diameter closed tube Newtonians, instruments that were difficult or impossible to collimate using a conventional single beam laser collimator.

Each collimator is individually lathe aligned for accurate collimation.  The one-piece die-cast and machined aluminum housing guarantees a stable alignment.  The compact size and lightweight make the Laser Colli an indispensable tool that is handy to keep in anyone's eyepiece box (thought we doubt too many will find use as a keychain..).

Optical Wonder Fluid and Cloth


 Baader Planetarium's Optical Wonder Fluid is the finest lens cleaner we have found.  It does a consistent job of cleaning oils and organic contaminants from stubborn multicoatings while leaving almost no residue.  Beyond being a superb cleaner, Wonder Fluid also includes unique properties.  Ingredients within Wonder Fluid are designed to prevent growth of the types of fungus that have been proven to damage (literally eat) lens coatings.   We've seen first-hand the results of this type of coating damage on costly APO refractors, and welcome the added measure of protection Wonder Fluid gives.

We use Wonder Fluid for the majority of our cleaning needs in our business and in the field, for eyepieces, prisms, refractor objectives and dielectric mirrors (Note: Cleaning of traditionally coated mirrors requires a much different process and uses common water and detergent - not lens cleaners and cloths).  We have found Wonder Fluid to be the best general lens cleaning solution for our purposes.  It is extremely lo-residue, and cleans quickly without the excessive fussing some cleaners require, and we really appreciate the antibacterial properties.

Baader's Optical Wonder Cloth compliments Wonder Fluid.  Baader's cloth is made from a finer grade microfiber than the typical lens cloths sold at camera stores or eyeglass stores.  When paired with Wonder Fluid, it is easy to keep lens surfaces clean and working like new. 

Our Own Thoughts on Cleaning:  Cleaning optics seems to be one of the banes of this hobby.  Everyone has to learn their own way on this subject, including finding their favorite lens cleaning potion.  Over the years we've tried most of the available lens cleaners, including some touted by friends or manufacturers as the best or residue-free, and found that most fall short.  Very few have come close enough for our own 'picky' tastes (some highly regarded and expensive 'high tech' cleaners have turned out to be real duds).   We try to keep our optics as close to new as possible - clean and free of visible residues or discolorations, even under bright light at varying angles.  Modern multicoatings are brutal in their ability to show the presence of tiny amounts of contaminants. 

In the end, we have only found one solution that produces completely residue-free cleaning - photometric grade acetone or alcohol.  Using these ultra-pure solvents takes care and practice to achieve a pristine surface that is  completely free of the faintest discolorations.  The effects of these discolorations are negligible in use, so we recommend avoiding over-cleaning in an attempt to eliminate every trace.  In general, we recommend most amateurs stick to less aggressive cleaners, particularly since there is now an excellent alternative - Wonder Fluid.

For detailed instructions on how to clean eyepieces and refractor objectives with Wonder Fluid and Cloth, please click the following link.  We also highly recommend the use of our Rocket Air Blaster to initially remove debris and fine particles from optics, prior to the application of fluid and cloth.

Rocket-Air Blaster


In our search for the best optical cleaning products for our own use in-house and in the field, we came across a product that stood head and shoulders above everything else we tried.  The Giottos Rocket Air Blaster immediately impressed us with its high-powered and focussed blast of air, making all the other 'hurricane' type blowers seem anemic by comparison.  

The Rocket Air Blaster's rigid venturi nozzle creates a narrow and extremely powerful jet, and the one-way inlet valve prevents suck-back through the nozzle.  At 7" overall height, the extra-large oval shaped natural rubber bulb fits perfectly in the hand and provides a large volume of air, delivering a long-lasting air blast that loosens even tough static-cling particles.  Thanks to the base 'fins' the Rocket-Air is free-standing for convenient use and storage. 

Highly recommended for both indoor use and field use (the thick natural rubber is tear-proof and resists both high and low temperatures).
