Hi,

Most recent observation attached. I should have stated originally that we're able to calibrate to 9122A.

Good structure and changes in the NIR.

Hi Guys,

Just a quick submission for PNVJ17261813-3809354.

This is from the Watson 24" PlaneWave at Obstech, La Sauce, Chile using the remote automated FlexSpec1 spectrograph at R=1750.

This instrument is still in its commissioning phase but given the interest in this object I thought these ...

Just a quickie to show the most recent incarnation.

A commercial 55mm lens in place of the 'standard' 30mm diameter doublet. (Upper and lower covers removed for clarity).

Much better end-to-end focusing across the visible range. This looks to be a marked improvement.

Look how much space it frees ...

Hi,

Added the CalibrexV2 to the UVEX3 and took this from my first session.

A few "teething" problems with the Calibrex but nothing major.

PS guys...

The LEDs are very bright! I could read my street's signs when taking dark frames with the blue LED illuminated.

Is this a fault with the LEDs I bought or have you experienced the same thing?

I think they may need to be attenuated.

AG Peg with the UVEX3/Calibrex. Not yet quite happy with the screen placement for Flats but I'm close to getting that sorted.

Hi Terry,

the photmetric slit is virtually the same mount/position as the Alpy air-spaced 'wheel'. They're interchangeable.
I might be wrong but it'll be very difficult to shoe-horn anything else in there!
The dimensions of slit-mirror-guide lens distances are very tight and you'll be hard pressed ...

Hi Guys,

The photos below shows my UVEX3 and Calibrex guiding/calibration unit.

It works astonishingly well.

A few mods of course (!). Two x 50mm focal length doublets in the guider for better quality images, a Shelyak photometric slit used instead of the Alpy and a "larger" servo power board for ...

Hi Alain,

Thank you for your response.

I can confirm that the servo I use is a 5V MG90S and that I'm using a 78L05 in the diagram you posted.
I've used a separate, direct, ground but still nothing. The servo just "ticks".

When I provide a separate 5.3V supply the servo works perfectly.

Perhaps ...

Hi Guys,

I've built the Calibrex (to go with my UVEX3) and all is well - except one thing...

I can't get the servo to move.

The servo works for other Sketches. I changed the servo just in case. I've provided separate power to ensure it's not the PCB.
The 78L regulator has a 4.98V output which ...
