Correct Photometry Aperture Radius / UCAC3 Download

Learned about applying the correct aperture radius as 0.8x FWHM.  The PinPoint engine provides FWHM. The FWHM is measured by doing individual Gaussian PSF fits to the 20 brightest unsaturated stars in the plate. Checked to see that the UCAC3 catalog downloaded successfully.

Visual PinPoint, UCAC3, ACP 6.0

Earlier this afternoon, Dick Berg was kind enough to have a look at my images that did not plate solve (see ACP forums). He had some good advice, but I don't think it explains away all the mystery of why one image solves, and the immediate next image on the same target, doesn't solve.  He mentioned more hot pixels in the second image, but that's only part of the problem.

Upgraded ACP Scheduler

DC-3 Dreams released ACP Schduler 3.3 today.  I still haven't got around to leveraging Scheduler, but I upgraded anyway.

First Data Submission Acknowledged by AAVSO

I submitted some data on Mrk 421 which was broadcast via a AAVSO Newsflash tonight.

Voice Agent Disabled in ACP

ACP unexpectedly crashed last night.  After a bit of sleuthing of my OS event logs I found out that something went amiss with tv_enua, the TrueVoice text-to-speech engine. Something in it faulted and took ACP down with it (this was confirmed by Bob Denny at DC-3 Dreams).  I liked hearing Merlin give little status reports about an ACP running plan, but not at the expense of an ACP crash.  Sorry Merlin, but you gotta go.

Upgraded to ACP 6.0

DC-3 Dreams issued a major release to ACP today.  I upgraded ACP to version 6.0 tonight.

Upgraded ECU

ECU is now 32-bit!  Upgraded the license today.

DSI Dark Library

I was annoyed by the lack of a dark frame being applied to my DSI guider images.  While a dark-subtracted image means less noise and an increased sensitivity to guide on fainter stars, I found the need to cover the APO guide scope to take a dark inconvenient and impossible in an automated set-up.

I began creating a dark library in MaxIm DL.  This is configured to point to the calibration folder of master frames (biases, darks, flats), and "full calibration" is set for the guider CCD.  Much better.

Filter Off-Sets

Determined B, V, Rc, Ic, and "None" filter off-sets using ACP Focus Offsets.vbs script.

ACP Scheduler

Installed ACP Scheduler today.  A little more of a learning curve to figure this one out.  Need to get some program stars and other targets in place to really leverage Scheduler.
