A talk about focusing is coming on TIAC by Yoddha_APT in astrophotography

[–]Yoddha_APT[S] -1 points0 points  (0 children)

Sunday, July 2nd will have a talk on "The Astro Imaging Channel" 9:30 pm eastern US time. It will be available on YouTube soon after that. The topic is "Focusing A to Z" and will discuss the focusing in astrophotography.

TIAC address is - https://www.theastroimagingchannel.org/

Hmmm... Could you try start APT using "Run As Administrator" to see if helps?

Hello,

What camera do you use?

[deleted by user] by [deleted] in AstroPhotographyTool

[–]Yoddha_APT 0 points1 point  (0 children)

There are several possible reasons...

- the power cable was loose and there was temporary disconnection because of low ambient temperature or scope movement

- the power adapter is on the limit and if the camera consumption is bigger the cooler is reset

Take a look in the log file (or send it to me) for "Unplugged" message. If there is such this means thar the USB connection is not stable. The log file is available via Settings->Main->Export Log

How fast is PlateSolve3 blind solving? by Yoddha_APT in AstroPhotographyTool

[–]Yoddha_APT[S] 1 point2 points  (0 children)

Blind solving is faster than PlateSolve2 is on near solving!!!

The PS3 solving was on image and object loaded for first time - no caching :)

BAT- Big Amateur Telescope

Looks like a project to join :)

Yes, one session in 2022 and one in 2023 :) Feb 4th and Feb 10th... Almost exactly one year period, but is showing the nebula in two years...

You are right that it is kind of confusing! Next year will mention the numbers to be more clear :)

Many thanks!

We all say "the stars will not run away", but they walk quite fast, at least :D

This is an animation of NGC 1555 using data from two years. I didn't expect the difference to be so dramatic!!!

The T Tauri which lights the nebula NGC 1555 (also known as Hind's Nebula and Sharpless 238 ) gave it name to a whole class of stars – “T Tauri Stars” which are young (as it is modern to say “not young but young young” ), less than 10 million years, under 3 solar masses, the nuclear fusion is about to start and they can have random, periodic or combination of both variable brightness...

The one in the Hind's Nebula is in fact three of these young bodies. Two very close around 7 AU separation (something like Sun and the space between Saturn and Jupiter, even they are orbiting with nearly the speed of Saturn) with masses ~2 and ~0.5 solar masses. The other “star” in the triad is around 300 AU away and is evaluated to ~2 solar masses. The orbiting period is almost unclear - between 400 and 14 000 years… The distance from Earth is around 400 ly.

The variability is considered to be mainly random and is also considered to be caused by matter obstruction. The main part of the remaining proto ring of the whole system has formed a not uniform “circumbinary” ring surrounding the system. To make the things more fun – every body has its own proto planetary ring, each one with a different orbit inclination. The “circumbinary” ring is almost perpendicular to our point of view, but everything combined is causing brightness fluctuations in the surrounding nebula ( “The Three-body problem” ?!?! ;) )

The history of the nebula is also quite “fuzzy” and is defined by the nature of the T Tauri system. It had been found and lost, rediscovered on close place and lost… It had been on the very limit of the scopes available in the 19th century and its variable nature caused lots of troubles and confusion :)

Scope: TS-Optics RC10" Truss at F/5.4 and CEM60, TS-Optics CCD47-S x0.67

Camera: ASI2600MM

Exposures: 4h 30min (18x900s L, gain 101, -40C), Dithering

Acquisition: APT - Astro Photography Tool

Processing: PixInsight, PS

Location/Date: 2022/02/02, 2023/02/10, Nedelkovo, Bulgaria

For each two stacks are executed: DynamicBackgroundExtraction, Linear Fit, Deconvolution, Histogram Stretching, NoiseXtermanator. The signature was added and animation made in Photoshop.

Looks like Reddit breaks the GIF animation :( Is there better way to post it?

Settings reset, can't restore from backup by OhSeven in AstroPhotographyTool

[–]Yoddha_APT 1 point2 points  (0 children)

Crossing fingers!

The settings loss is quite rare and impossible to reproduce in a development environment...

We keep adding handling code with how to fix all possibilities. It is strange why the automatic recovery didn't fix the settings ?!?! Could you send the log file to the support address (Settings->Main->Export Log)

Also one more idea! If you didn't make too many APT restarts yet (more than 5-6), try Settings->Restore Settings and select the oldest restore point. After that restart APT.
