Processing the 21 Jul Centaurus A data showed the nucleus is saturated: a single 300 s luminance sub reads 65313 ADU in the core, so the deep stack is clipped there and the core cannot be recovered by processing. The only fix is more data at shorter exposures. plans/hdrcore-t32.txt is that data: L 8x60s, 8x15s and 8x5s plus RGB 5x30s, all BIN2 so the frames register against the deep stack without rescaling. The ladder spans a factor of 60 below the 300 s subs, which covers the unknown true peak of the nucleus, and the RGB gives the core its colour. 18.2 minutes of imaging, about 25 points. Uploaded to T32 and verified byte-identical, then booked for the evening of 22 Jul, 18:50-19:50 SSO local, which is the same window in which the deep run actually succeeded (T32 has a 35 degree elevation floor and Cen A is an evening target). Verified in MySummary; quota now 7:05 of 8:00. The wider point is recorded in CAMPAIGN.md: bright targets need a short set budgeted alongside the deep run. NGC 6744 has already been shot without one, and 47 Tuc and the SMC in queue #5 will certainly need one, a globular cluster core being the fastest thing there is to saturate.

## Done
|
|
|
|
- 2026-07-17: repo created on git.discworld.casa, Default Workflow scaffold copied in.
|
|
- 2026-07-17: specs sheet snapshotted to data/itelescope-telescopes.csv (24 scopes).
|
|
- 2026-07-17: TELESCOPES.md written: per-scope reviews for all 23 active telescopes
|
|
plus a choosing guide (T74 noted as in commissioning, no specs published).
|
|
- 2026-07-18: TARGETS.md written: southern targets invisible from the UK (dec tiers
|
|
from lat 51.5°N), matched to Q62/X07 scopes, seasonal booking calendar, and a
|
|
July-August starter campaign (T33 free, T71 narrowband, T73 galaxy, T8 LMC later).
|
|
|
|
## Done (recent)
|
|
|
|
- 2026-07-20: NGC 6744 on T59 SUCCEEDED (reservation 749227, txn 851148): full
|
|
LRGB dataset on the scope server (L 15x300s BIN1, RGB 7x300s each BIN2),
|
|
previews verified clean. Billed 381 pts (est was ~240: see the rate
|
|
correction in NOTES.md). Balance now 2,257. Ledger updated in CAMPAIGN.md.
|

|
|
|
|
- 2026-07-21 ~08:55 UTC: free T33 47 Tuc retry booked as reservation 749314
|
|
(grid-verified), third attempt at the first-light test, runs 14:05-14:50 UTC
|
|
21 Jul, costs 0.
|
|
|
|
## Done (recent)
|
|
|
|
- 2026-07-21 11:40 UTC: Cen A on T32 verified COMPLETE (billed 160, NGC5128
|
|
images on the scope server), and queue #2 (Corona Australis on T8) booked for
|
|
the night of 22 Jul, 21:45-00:45 SSO local, which brackets the target's
|
|
culmination instead of chasing it down the western sky. Rate model rebuilt
|
|
from two actual bills. Details in the CAMPAIGN.md session note.
|
|
|
|
## In progress
|
|
|
|
- T33 first-light test on its THIRD booking (749314), which had NOT yet run as of
|
|
11:40 UTC 21 Jul: it starts 14:05 UTC. Verify after 14:50 UTC (images and logs
|
|
on t33.itelescope.net:8033 were still empty/stale at 11:40, as expected). The
|
|
two prior free reservations (749228, 749229) expired unused with reschedule=No;
|
|
if 749314 also fails to run, stop rebooking and either walk it in (POST
|
|
plan.asp per plans/README.md) or drop the free objective.
|
|
- HDR core set on T32 runs 08:50-09:50 UTC 22 Jul (plans/hdrcore-t32.txt, ~25
|
|
pts). Verify after 09:50 UTC, then download and blend it under the saturated
|
|
core of the 21 Jul Cen A stack. The processing pipeline for that stack lives
|
|
in the user's Downloads\NGC5128\20260721\stacked\scripts folder, not in this
|
|
repo, with METHODS.md alongside it.
|
|
- CrA on T8 runs 11:45-14:45 UTC 22 Jul. Verify after 14:45 UTC: images under
|
|
/images/qisback/T8/ on t8.itelescope.net:8008, then the actual bill from
|
|
account/history.aspx into the ledger. This is the first T8 bill, so it also
|
|
fixes T8's effective rate (card says 130/hr; trust nothing until observed).
|
|
- DRAIN CAMPAIGN ACTIVE (see CAMPAIGN.md): spend the full balance by 10 Aug,
|
|
then cancel before the 12 Aug renewal (user confirmation required for the
|
|
cancel itself). 541 of 2,638 spent; 2,097 remain. The x1.6 estimate multiplier
|
|
is WITHDRAWN: billing is on plan imaging minutes, and per-scope rates must come
|
|
from actual bills (T59 127/hr, T32 80/hr observed; the NOTES rate card is
|
|
unreliable). On current numbers the campaign UNDER-spends by ~800: plan extra
|
|
or longer runs, do not trim. Reschedule flag never sticks (grid always shows
|
|
No): treat every reservation as one-shot and verify the morning after.
|
|
Download the NGC 6744 and NGC 5128 data from data.itelescope.net before the
|
|
10 Aug cancellation sweep. Update the CAMPAIGN.md ledger after every session
|
|
from account/history.aspx.
|
|
|
|
## Pending
|
|
|
|
- Automation: map the ACP web endpoints on a per-scope server (start with free
|
|
T33) for plan submission and status; explore lookup.itelescope.online (the new
|
|
planner); enumerate more /DataService.svc methods. Recon notes in NOTES.md.
|
|
- Campaign impact (status seen 2026-07-18): T71 and T73 are offline
|
|
(development/mount testing), as are T2, T17, T18, T20, T25, T30, T72, T74,
|
|
T75, T80. T8, T33, T32, T59 at Siding Spring are operational. Re-plan the
|
|
July-August campaign around T33 free time and Siding Spring scopes until the
|
|
Chile rebuild finishes; re-check status before any booking.
|
|
|
|
- Fill in T74 when iTelescope publishes its specs.
|
|
- Reconcile the retired scopes (T9, T19, T31, T69): the support article still lists
|
|
them but the maintained sheet does not; confirm status and note it.
|
|
- Optional: per-telescope detail pages on support.itelescope.net (links in
|
|
DECISIONS.md) hold photos and operational history if deeper entries are ever wanted.
|
|
- Periodic refresh: re-export the Google Sheet and diff against data/ to catch new or
|
|
changed systems.
