Now we know what that new full frame color camera was for.  I hope to see some sample images soon.

At last, our exciting news:

 

The Quest:  Design the largest, fast, highly-corrected, airline transportable refractor that can cover a full-format CMOS chip with pinpoint stars to the corners when coupled to its matched Telecompressor-Corrector and provide superb visual performance.

 

The Solution: 110mm StarFire GTX with its optional Telecompressor-Corrector ready for your next astronomical adventure near or far. Perfect for the 2024 eclipse and a quick and easy scope for any night or day you have a few hours available to observe.

 

Check out our new webpage with preliminary details that will be updated as final tweaks are made to the mechanical design.

 

In order to give everyone an equal chance to obtain this versatile scope, we plan to use the same random-drawing format that we used for the 92mm Stowaway. After we establish the price and have more details regarding the case, Telecompressor-Corrector, and other accessories, we will announce the signup for the random drawing. During the week-long signup period, you will have an opportunity to enter and submit your contact information. From this group of interested people, we will randomly choose those who will be notified of the opportunity to purchase a 110mm StarFire GTX.

 

If you are interested, watch for announcements on the Availability tab of 110mm webpage, in this forum, on our Facebook page and our newsletter. If you would like to receive our newsletter so that you don’t have to be vigilant about watching the website or forum, you can sign up in the black banner at the bottom of our website.   https://www.astro-physics.com/

Sorry, it's boring here with clouds every night now that the auto-clear weather has passed from the full moon).
The moon of course exerts a pull on the oceans. Oceans are made of water. Clouds are made of water too. So, following that logic, the moon pulls clouds up and out of the way and leaves behind a clear sky. So, when the Moon is not in the sky, there's nothing to pull the clouds away, and therefore they hang around and thumb their noses at astro-imagers.

There is an old mathematical problem you can restate as follows (usually given about a monk walking up a hill and back down):
If they leave toward Grandma's house at noon, and arrive 14 hours later for trip #1.
If they leave from Grandma's house at noon another day for the return and arrive 14 hours later for trip #2.
Assume exactly the same path and same arrival clock time, but they can vary the speed, stops along the way, etc.
Did they actually arrive at the same exact point at the same time of day on the two separate trips?   
You can even assume they tried NOT to arrive at the same exact point on both trips at the same time of day.
Math can prove they did indeed arrive at the same point at the same time of day, but (without more info) you cannot prove exactly where that was, or what time it was, just that it happened.
Thus thinking of this unknown point as a half-way point, since it is mathematically impossible to know quite where it will be, Roland is arguably correct to say that all points could be this mid-point.
Not that we had any doubt that Roland was correct of course.  😊

Great news on the CP4 version. I have been anticipating it for a long time.


Re: AP1100 autoguiding

 

We’re putting the final touches on the CP4 version and I hope to release it in the next week or two. While not Roland’s big announcement, it is also important.

Hi Christophe,

Congratulations on acquiring the 1100GTO.  You will love it!

Pointing errors can have several sources:

  • The most common cause of pointing errors is polar misalignment.
  • If the RAPAS was not properly calibrated, it may not give good results.  If it was calibrated incorrectly, it will certainly fail to give good pointing.
  • Orthogonality affects pointing, especially nearer to the pole.  Orthogonality problems show themselves most strongly after a meridian flip.
  • Pointing problems are almost never the fault of the mount.

As Oliv points out, one of the first things to determine is whether your drift is in RA, Dec or in both axes.  You can easily determine which direction on the chip is RA by stopping tracking for a short while in the middle of an image.  The streak that results will be in the direction of RA.

You will need to either create a good PE curve or autoguide.  If you received the copy of PEMPro that came with the mount, you can both cure the periodic error and fix the polar alignment at the same time.

You may or may not need to remesh the gears.  This can be quite easily tested using the instructions in our website's technical support section.  https://astro-physics.info/tech_support/mounts/gear-mesh-1600-1100-mach1-2014-10-24.pdf

I can't confirm as I don't have kids, but this response must be included in some new parent owners manual or something.
