Baader UHC-S Filter
Here I am today, after various trials, groped to write a satisfactory review of the Baader filter in question. I waited a bit before deciding to write a post, because I had not got to try it on a large number of objects deep and could not provide adequate feedback, but now, after using it on various subjects can say to be fully satisfied.
We start from the beginning, however, just open the plastic bag and examined the filter a bit, the first impression I had was reliable and well executed. Even comparing it eye and look toward the lights of home, you can indeed appreciate the quality. A defect that could possibly annoy those who use it do not screw the filter on the eyepiece, but positioned between the lens and the eye is that if you have behind you a strong source of light, the surface of the filter becomes similar to a mirror ... but in a place of observation, this is a condition hard to find, so ... Now to the actual test in the field. The first observing session after receiving the filter has been paid, as expected, to M42, the Great Nebula of Orion. Without the filter, in a wide-field eyepiece, the nebula was clearly visible with a color that it seemed to me green (some say it actually gray, but green and it seems to me enough! ) As usual, is easily noticeable even M43. With the filter on the other hand, the sky background was much, much darker, while the nebula was visible in a more extensive and M43 are also well noted, all clearly separated from the pitch black of the sky provided by the Baader UHC-S ( and as you can see from the chart above, it is quite generous).
The second test was always performed that evening, at the M1 and M78, respectively in Taurus and Orion. Both subjects were difficult to see without a filter, and passed almost unnoticed, if not done carefully, while looking with the filter, were both clearly visible and contrasted by a black sky, that resembled that seen in the mountains (although unfortunately it was just an illusion). The third test was conducted today on M57, the Ring Nebula in Andromeda and M31. The first, escaping without a filter, of course, was visible with the Baader UHC-S, even at high magnifications, even if more is going on with them, the more the image loses its brightness, especially with the filter, the observation of the second subject Instead, the Andromeda galaxy, has not undergone improvements (nor deterioration) , excluding the darkening of the sky background, with the UHC-S, as expected.
In conclusion, I think it's a good filter, and if your interest is in the deep sky, you definitely have it in your briefcase. The resulting image as you can see from the tests is excellent, you can see otherwise hidden details, see well and sometimes you have to watch something that no filter in averted vision. The only drawback is the low light loss, which is contraindicated due to go up a lot with the magnification, but miracles do not exist in this world ....

Electric Saving Box Circuit
Homemade
As the wise, when it rains, the amateur goes shopping ... or invents and builds!
Propio of the latter talk about today: the self-construction of a Frame altazimuth made simply with hydraulic hose and fittings without the use of various other components and welds. Before continuing with the article, may I say that without the help, expertise and especially the ideas of a friend amateur astronomer named John Bruno, this beautiful frame would never be born! Well, having said that then begin to explain in detail all the components used, starting from the base:
- Three 90 ° fittings for the construction of the foot of the mount;
- Two "T" for use as joints between tubes;
- Four short tubes (You can choose the length) to achieve and the base itself;
- A long tube to make the column of the frame (again, you decide the length);
- A connection to 90 ° or "T "to realize the heart of the mount, that will give the movement in azimuth;
- A screw cap, to be connected to the heart of the mount, which will give the movement in height;
- A bar of iron or other metal made by a locksmith or hardware bought in for connection of the rings of the telescope.
Everything here, through these few components (and especially cheap, even better if you have a plumber friend! ) Is possible as you can see from the photos, a robust, secure and stable altazimuth mount. I used tubes are not too large, but depending on your needs, you can choose the diameter of the various components, but even with those chosen by me, the frame holds egreggiamente is my Celestron 114, Celestron is a 150/750 to a friend , the vibration of the blows on the pipe will soften in a few seconds and the movements are smooth but controlled. As you can see from the photos there are no welds, since all components of the frame are connected by interlocking threads, the only component on which I had to make was the metal bar on which the rings are connected to the telescope .. . make sure I could pay the bar the screw cap, but I did not want to go out with the rain, and then I used a two-component adhesive (found in hardware stores) that I had available at home, and that hardened becomes harder and stronger than concrete!
So ... who wants to compare the field with a EQ5? : D

altazimuth mount 20mm wide angle eyepiece TS 70 °
Today, I am writing to review my new eyes, as the title:
TS 20mm Wide-Angle and 70 ° apparent field.
eye on this there is little to say, in my opinion seplicemente excellent, especially when in relation to its nominal price. The 70 ° field are very comfortable, Perseus twice saying it was fully visible in the eyepiece, so much so that because of the convenience and good workmanship of the latter, I have avoided using other eye to focus more on observation.
Same for M42 which, although (with Baader UHC-s filter) very extensive, was completely centered in the eyepiece.
The difference with a single eyepiece 52 ° field is so apparent and it shows, in fact the same magnification, the vision in one eye wide field is much better! (In the picture below you can compare the difference between two eyes, with different visual field).
Putting aside the wide field of view for now, we talk about the optical quality of the eyepiece TS; is correct up to almost 90% of the field, and the resulting image is sharp and well contrasted . Compared with the resulting image from my Celestron 25mm eyepiece, the vision is clearer, but with more contrast and is generally better. It must be said that you can see similarities between this eyepiece, and identical but more expensive than other known brands. Ultimately, if you want an eyepiece with good optics and a field of apparent good, for a ridiculous price for an eye, do not hesitate and buy it, you will not regret!

How Can I Fake A Kidney Stone
Planetarium PDA
I am here today to talk about, and try to briefly describe the duties of a planetarium program for Palm: Planetarium, which I started using just recently and I found very useful , with the help of the many functions offered, and the ability to customize it in various ways and for different uses. Planetarium is available for PDAs, but you can run it on Windows Mobile handhelds and smartphones through an emulator application for PDA operating systems of this type: StyleTap.
certainly see a planetarium on a handheld from the small screen may have different disadvantages, but in my humble opinion, the advantages are several.
First, being able to eliminate at once the star maps, sheets for notes and other things that slow down in some way the night vision of heaven. But let's see briefly what are the main features of the program, just started first thing, of course you have to enter data for your location of observation, you can enter a number for all uses! Without this you just need to start using it, with a view available in two versions: the first is a screen on the compass, which shows the objects in azimuth and in height, the second is the normal vision of the night sky from your location. The various items are grouped (and selected) through the pull-down menu above, and once you select appears on the screen surrounded by circles of Telrad (useful function in my opinion).
If you need to update or you can of course Replaces the database objects, asteroids, comets, etc., etc., directly from the manufacturer's website, where you can download different types of databases and file extensions (such as plug-ins to check for new motorized telescopes through this program.) If you want to at this point you can press the icon with the "i" to get detailed information on the object that you have framed, while pressing the icon of the field of view, you can increase or decrease zoom to suit your needs. While pressing the clock icon, you can see the sky will look like in the future, is used to schedule future observational outputs (you can do the same thing with the moon phases for example, through the display mode socket) . One last interesting feature is the diary of observations incorporated Planetarium, accessible through the dedicated icon, where you can quickly write down an object just observed, then transfer everything when you are home more comfortable!
The program can be downloaded from "http://www.aho.ch/pilotplanets/" in the demo version, if you like you buy it ... otherwise you can continue to use the demo ... that never expires and has no limitations! The only trouble is that you keep the warning that appears every now and remind you that you are using the demo version.
