Hello friends,
this image was done as a quick test of our newly designed and produced 140mm F/6.5 APO triplet using Ohara FCD100 and two types of Lanthanum. This superior design is hitting highest marks. This image is a stock of 60 1-min images, taken from center of very light polluted Tucson (second largest city in Arizona). My friend, owner of 140mm TEC told me that he is not able to make better quality image using his truly excellent TEC 140mm refractor. We are pleasantly surprised and humbled by this fact.
I built my first telescope when I was 9 years old. I made it of eyeglasses and 10x jewelry loupes. I was so proud of my achievement back then. Today, some 53 years later, Im so proud to offer this superior quality APOCHROMAT. To be able to produce such quality as such low price is worth of celebrating. So we are currently running a special and if you purchase our 140mm F/6.5 together with Starizona's Apex ED-L field flattener/reducer you will get additonal 5% off.
We have currently 3 lenses in stock.
A new prototype of Phantom FCL 140-6 is finished, we will start producing these APO refractors / astgrographs in the next few weeks. We are already offering this telescope on istar-optical.com and you can pre-order yours today!
