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.

Summer Camp Gawh 7 / 14 July 2010

again this year and 'The time has come the summer camp of the Amateur Astronomers Group William Herschel.

On my site I have included a series of photographs taken in those days, but what about the record, refer to the excellent sites of other members, but here I write about topics more 'purely technical.

From the point of view of astronomical photographic production have not been very fortunate in that electrical problems have haunted me all the time, but having the good fortune to remain for several days with friends much more 'experts (including Leonardo, Lucius and I'll be), I was able to take advantage of their knowledge to understand my problems and try to overcome them for the future .

As for the power supply of the equipment I had prepared a system with a regulated power supply with battery backup.
I was able to verify that the system works well, because some falls at the mains at 220V telescope and CCD continut have to operate without blocking issues.
Unfortunately, the 12V cable (6 sq.) that I had prepared seems to be too long and cause interference that rovinano le fotografie.
Dovro' provare ad accorciarlo ed inserire delle ferriti, nonche' provare ad attorcigliare i due fili.



La montatura, che non inseguiva bene, con errori piuttosto consistenti, superiori ai 5 pixel, con picchi saltuari decisamente superiori, grazie agli insegnamenti ricevuti si e' stabilizzata su un buon massimo di un pixel ed una media decisamente migliore.
Stupidamente pensavo che inseguendo con il C8 a F/10 avrei dovuto avere degli errori di guida che fotografando a 450 mm di focale avrebbero prodotto delle foto perfette.
Ho invece imparato che, almeno con la montatura G11 di cui dispongo, e' meglio inseguire con focali decisamente inferiorio al metro.
Another mistake that I did was set an integration time of the room being driven too high.
From what I heard from other friends, and read on the manuals and the Internet, the integration time was meant to avoid seeing the chase, so he should be around 3 seconds. Instead
using as guides the telescope Maksutov Skywatcher 5 "borrowed from David, and setting the camera driving at 0.5 seconds in 2x2 binning, tracking errors are now the ones mentioned above.

but I am afraid 'that part of the interference problems recorded is due to its maggor "speed" action of the frame.
I think, also for the fact that I had put together in a single beam and USB cables room than those of motor control, this higher speed 'Frame of action has resulted in underexposed.



more ....

the end I still tried to salvage the pictures made and these are the results, taking into account the lessons drawn by Leonardo (at least to what I still remember)!

All photos are made with MagZero Mz8 Fsq85 and Takahashi, processing and MaximDL Astroart.


Shii 91
not apparent some nebulosity '.
E 'likely to be a very Evanescene object and do at least H-alpha filter, although it is indicated in the catalog with luminosity '2.
sum of 5 exposures of 300s, flat and dark.



Retainer 54 would be a beautiful object, but with the problems brought by electrical interference and only 2 exposures of 300s, with flat and dark, and the result 'and that'!



Ngc 7000 In this photo of Pelican and North America seem to not be noticed electrical interference.
Sum of 4 poses 300s, flat and dark.




M16
Sum of 13 exposures of 300s, flat and dark.
Two different calculations, in the second I think you put more 'prominence in the haze' around.


M4, Ngc6144 ed un accenno di SHii9, intorno alla stella luminosa in alto, naturalmente il tutto condito dalle solite interferenze elettriche.
Somma di 7 pose da 180s, flat e dark.


ShII 108 intorno a Sadr (Gam Cyg), visibili anche Ngc6910 e Cr419 (in alto).
Somma di 6 pose da 600s, flat e dark.


Ancora M4 e Ngc6144, ma tentando di riprendere in particolare SHii9, che qui risulta leggermente piu' evidente.
Somma di 4 pose da 300s, flat e dark.

La Balma - 11-12/6/2010

Anche il tentativo fatto in questo fine settimana si e' risolto in un nulla di fatto.

Accordatomi con Saro, I went to Balma in the early afternoon of Friday '11 Accommodation in the refuge, while I preferred to opt for the Blackbird.

Having previously verified that the forecasts were not good equipment I brought with me the "light", that 'the Tecnosky 80/560 refractor mounted on a Celestron mount Nexstar5 If you find Used without optics.
used in visual and not 'to much' but prevlentemente account to use it for "educational" with the Group and from time to time for my comments.
In fact, with the Baader Hyperion 5mm eyepiece, from about 110 magnifications, the Sun and the Moon are totally in the field (36 'approximately), giving few details.





However, Saro (ottimista!), has instead decided to mount the usual photographic equipment.

After dinner we then stationed hoping to do what we proposed, but the weather did not agree with us!

At one point we thought we were lucky, 'cause it was all open, but after half an hour and' started the typical ballet "Balma" clouds.

Well ... two in the morning we threw in the towel and went to sleep.

the morning and I'll be 'unable to connect to the internet to check the weather of the day, and noticed how the forecasts were worse than the day first, decided to dismantle, closely followed by myself .... Luckily I had a lot of material! (


The arrival of Saro, already 'in the clouds:)
