Re: Deep Space
May 1st, 2009Many thanks for your link regarding the price.
Now I got to concentrate in getting all the appropriate lenses for deep space.
It sure is a fun clean and very enigmatic hoby.

Good day Juan, I got the telescope for $100 at the end now I feel better and surprised how low the price has become for the MEADE EXT60AT.
Many thanks for your link regarding the price.

Socrates,
A two and a half inch telescope is not a deep space telescope. At best you will be able to look at the moon and some of the planets in our solar system. You say you have to get the appropriate deep space lenses. I assume you mean the eyepieces. Did your telescope come with eyepieces and right ascension and declination motor drives? The Meade EXT60AT is a very basic, entry level telescope, and I hope it's limitations won't drive you away from astronomy.



Most definately I am enjoying it Socrates! It's awesome!!
I was away this week as well and just noticed your response, thanks! I'm happy to see that many others are enjoying it as well! What an awesome universe!

Good day Juan, yes the eye pieces it came with a 25mm and a 9mm, you are correct this is an entry level telescope, it is however providing that beginners enthusiasm by even looking at the moon, I will eventually and soon upgrade to the real thing like something like this picture below. But for sure I will be spending time on the subject in the years to come.

Socrates,,,Did you know that that telescope is a simple Dobsonian with no way to add a motor drive and no way to do any kind tracking or any kind of astrophotography?

How do you know? Let me guess. You can do the math. In the world of bleak bottomless selective skepticism you are in a class beyond merely obcessive.

Good day to you Juan, this is what I love about you and Dexter; you are always willing to help a fellow forum participant. I am glad you brought that to my attention Juan, that is very limiting if one can’t do the things you are mentioning. I am taking all this info and putting it to good use many thanks.

I find my skepticism quite useful, thank you, but it's nice to see your usual ad hominem fallacy again. At least you're consistent.
Yes I can do the math, but you don't need the math to discount what Edgar Mitchell's claiming. He's been promoting nonsense for years, starting I think with his "discovery" and endorsement of Uri Geller, which he's never retracted despite Geller being a proven fake. He claims he was supernaturally healed of renal cancer remotely by a kid in Vancouver calling himself Adam Dreamhealer, though he never was diagnosed with renal cancer in the first place. He's still claiming the Roswell Incident involved a real crashed alien spaceship, despite it being thoroughly explained many times since the records were declassified. He's not playing with a full deck. You might usefully try examining your own credulity a bit.

Socrates, Meade has a 5 inch f14 schmidt Cass with the autostar feature that is about the same price as the Dobsonian you mentioned. It would have about four times the light gathering of your two and a half inch.

"In the upper left-hand corner is an easily recognized drawing of the phonograph record and the stylus carried with it. The stylus is in the correct position to play the record from the beginning. Written around it in binary arithmetic is the correct time of one rotation of the record, 3.6 seconds, expressed in time units of 0,70 billionths of a second, the time period associated with a fundamental transition of the hydrogen atom. The drawing indicates that the record should be played from the outside in. Below this drawing is a side view of the record and stylus, with a binary number giving the time to play one side of the record - about an hour.
"The information in the upper right-hand portion of the cover is designed to show how pictures are to be constructed from the recorded signals. The top drawing shows the typical signal that occurs at the start of a picture. The picture is made from this signal, which traces the picture as a series of vertical lines, similar to
ordinary television (in which the picture is a series of horizontal lines). Picture lines 1, 2 and 3 are noted in binary numbers, and the duration of one of the "picture lines," about 8 milliseconds, is noted. The drawing immediately below shows how these lines are to be drawn vertically, with staggered "interlace" to give the correct picture rendition. Immediately below this is a drawing of an entire picture raster, showing that there are 512 vertical lines in a complete picture. Immediately below this is a replica of the first picture on the record to permit the recipients to verify that they are decoding the signals correctly. A circle was used in this picture to insure that the recipients use the correct ratio of horizontal to vertical height in picture reconstruction.
"The drawing in the lower left-hand corner of the cover is the pulsar map previously sent as part of the plaques on Pioneers 10 and 11. It shows the location of the solar system with respect to 14 pulsars, whose precise periods are given. The drawing containing two circles in the lower right-hand corner is a drawing of the hydrogen atom in its two lowest states, with a connecting line and digit 1 to indicate that the time interval associated with the transition from one state to the other is to be used as the fundamental time scale, both for
the time given on the cover and in the decoded pictures.
"Electroplated onto the record's cover is an ultra-pure source of uranium-238 with a radioactivity of about 0.00026 microcuries. The steady decay of the uranium source into its daughter isotopes makes it a kind of radioactive clock. Half of the uranium-238 will decay in 4.51 billion years. Thus, by examining this two-centimeter diameter area on the record plate and measuring the amount of daughter elements to the remaining uranium-238, an extraterrestrial recipient of the Voyager spacecraft could calculate the time elapsed since a spot of uranium was placed aboard the spacecraft. This should be a check on the epoch of launch, which is also described by the pulsar map on the record cover."
