Homemade Sour Cream Powder

tests CCD - Saturday, 21/08/2010

Today I did several tests to see if I could find the problem causing photos striped.

Maybe I could find it!

Chronicle of evidence:

1) Both CCD and neighbors are active as owner.
-Entrambi collegati con Maxim5
-I cavi usb sono completamente attorcigliati insieme e ammucchiati
-L'alimentatore e' acceso
-Ci sono alcune spire annodate sul cavo da 6mmq di alimentazione a 12V (c.a. 5) si presentano cioe' con cavi incrociati a X
Risultato:
Si vedono alcune (2 o 3) righe orizzontali sulla mz8
Il FFT sembra evidenziare struttura ripetitiva, ma identica su tutta l'immagine con andamento diagonale dal basso verso l'alto, da sinistra verso destra

2) Stessa situazione ECCETTO:
-Spire aperte
-Atik allontanata a circa 1mt
Risultato:
Non sembrano piu' vedersi le righe orizzontali
Il FFT non sembra diverso dal primo
Confermo che comunque non si vedono righe orizzontali

3) Riprovo riavvicinando i due ccd
-I due ccd sono a non piu' di 5cm l'uno dall'altro
Risultato:
Non sembra di vedere righe orizzontali
Il FFt e' come i precedenti

4) Riprovo incrociando le spire (sul cavo di alimentazione generale a 12V)
-Fatto 7 "incroci"
Risultato:
Peccato! niente righe neanche cosi'!!!!!
Anche il FFT non sembra diverso

5) Riprovo incrociando anche i cavi batteria
-Arrotolati completamente
Risultato:
Nessuna riga!!!!

6) Riprovo come sopra attivado la Atik 314L+ come se autoguidasse ma senza collegare il telescopio
Risultato:
Here! The photo and 'full of lines!!
The FFT does not seem different

7) Retry as "6)" but eliminating the crossings on all the electrical cables
Result: Always
lines that seem even increased compared to "6)" where the wires were all cross

8) Try again as "7)" but the two rooms away about three feet
Score: Photos
always ruled

9) Please try turning off the power supply
Score: Photos
always ruled

10) Try again with power on but WITHOUT autoguide
Score: Photos
again ok!

11) autoguiding Please try changing the USB connector on PC-
Now the two CCD are connected to USB ports on opposite sides of the pc:
Atik Mz8 left and right again on the usual connector
Score:
The photo and 're-striped!

12) I try as above but changing acquisition program ripetto than driving
Astroart acquisition
= Maxim = autoguide
Score:
The picture does not appear to present lines again!?!
Whether it's a compatibility problem 'of the rooms on the same program (MaximDL)? There
'but' the problem that Maxim seems to go in slow motion since the Mz8 and 'connected to Astroart!

13) I feel more self-guided with Maxim (and 'the only one that supports more than Astroart Atik 314L +) and acquiring con il programma nativo della Mz8 (CCDCap)
Risultato:
La foto anche qui sembra ok!!!!!!
Forse non devo solo usare lo stesso programma (Maxim) per guidare e catturare immagini!!

14) Riprovo a fare una foto con Maxim ed autoguidando con Maxim
Purtroppo si e' inchiodato maxim e ho dovuto riavviare il pc.
Spero non infici le prove fatte!
Risultato:
In effetti si sono ripresentate le solite righe

15) Riprovo usando Astroart sia per ripresa che per autoguida
Con astroart bisogna pero' usare due sessioni diverse per giudare e fotografare
Risultato:
La foto risulta priva di righe orizzontali!

CONCLUDO CHE MZ8 E ATIK SONO INCOMPATIBILI IF USED BOTH WITH MAXIM DL.

What If My Dog Is Pooping Blood

La Balma - New Moon 6-7/8/2010

Having seen the weather forecast for mid-August we were not very good I tried this out for two days over the usual refuge Prato Nevoso.

As mentioned in the previous post I had prepared the equipment planning to improve the situation:
Berlebach tripod-New Planet;
-separation of all the data cables and power supply.

Unfortunately the desired results have not been seen!
autoguiding continue to occur according to the usual photo "Arrigoni"!

At this point I still have a lot of variation with ':
"I have already' tried to feed a 12V or 220V - no change;
I-shortened 12V cable that comes from food to diramamzione "star" that I got - no results, but I did not think of seeing as even feeding all the individual transformers with a 220V to 12V did not change anything, I tried to separate
- all the cables (2 usb cables and power supply unit, which were joined together in a single coil) - no result.

The next time I can still try:
-redirect Mz8 turning so as to guide the connectors in the opposite direction to the guide camera;
-Increase the separation between the two telescopes using a double bar over 'long;
- Replace the electronic control of the mount (MicroGiga DA1) with another (I can take? FS2? Gemini? ? )
Hand-Drive?! : (-The problem seems to occur only with the guider running!

HELP!

Add a couple of photos as it is now the telscopio.

The new stand looks more effectively 'stable of the old post, although I regret the system of leveling a leveling screws, which did not require removing the tripod from the ground when you stretch your legs change the footprint.
sinful it was unable to find the best legs column!

To continue using the C8 for autoguide I added a gear F / 6.3 that already 'had.
In this way, using 2x2 binning, and the situation 'similar to when I used the David Mak has a focal length of 1500mm compared with about 1200 of C8 in this configuration.
