- Reservation 749302 created and grid-verified: T32, night of 21 Jul SSO, 18:50-21:50 local (08:50-11:50 UTC 21 Jul), plan cena-t32.txt, est ~350 pts at the corrected x1.6 rate with 25% moon discount (46% moon ~30 deg away). - The original queue slot (00:35-03:35) was an astronomy error: T32 has a 35 degree elevation floor and Cen A culminates ~17:10 SSO local in late July, sinking to ~11 degrees by midnight. Evening is the only viable window; noted in the ledger so the mistake is not repeated. - Reschedule flag confirmed to never stick (second booking posting RescheduleCheckbox=on that renders as No in the grid): every reservation is one-shot, verify the morning after. - Quota math recorded: 5h20m of 8h held; queue #2 (cra-t8) plus the free T33 47 Tuc retry must wait for the Cen A run to release its 3h (~11:50 UTC 21 Jul). Full remaining queue at corrected rates ~2,530 vs 2,257 balance: Phase 3 needs a ~270-point trim once real bills confirm the rate model.

# Drain campaign: spend 2,638 points, then close the account
|
|
|
|
Decision (2026-07-18): use the full points balance on southern imaging, then cancel
|
|
the membership. Constraints and policy facts that shape the plan:
|
|
|
|
- Balance 2,638 points; Plan-40 renews 12 Aug 2026 (GBP 32). Cancel BEFORE renewal.
|
|
- Points cannot be refunded, and cannot be used without an active subscription
|
|
(support article 142963). So: drain first, cancel last, in that order.
|
|
- **Cancellation target: 10 Aug 2026**, two days before renewal. Cancellation is
|
|
submitted via MyAccount/Cancel.aspx and requires explicit user confirmation on the
|
|
day; Claude must not submit it unprompted.
|
|
- Rates: see the rate card in state/NOTES.md. Billing is per minute of imaging time.
|
|
- Moon: bright nights roughly 24 Jul - 2 Aug (full ~29 Jul); dark again 5-12 Aug.
|
|
Full-moon week includes free access promotions; paid draining focuses on dark and
|
|
grey nights, narrowband carries the bright week.
|
|
- Scope availability is volatile (much of Chile offline as of 18 Jul); re-check the
|
|
status line on go.itelescope.net before every session and substitute freely.
|
|
|

## Session ledger

Update after every run: date, scope, target, imaging minutes, points charged
|

(from account/history.aspx), cumulative spend.

|
|
| 2026-07-19 | T59 | NGC 6744 | ngc6744-t59.txt | 180 min | ~240 (0% moon disc. until 21 Jul) | **381** | SUCCESS (txn 851148): ran 00:05:22-03:29:56 SSO, Time Used 3h24m32s, 0% moon disc. Full dataset on scope server: L 15x300s BIN1, RGB 7x300s each BIN2; previews checked, round stars, galaxy clean: no refund case. Effective rate ~112 pts/hr of WALL time (not the 80/hr imaging-time estimate: see NOTES rate correction) |
|
|
| 2026-07-20 | T33 | NGC 6752 | ngc6752.txt | 17 min | 0 (free) | DID NOT RUN | reservation 749229 expired unused: no images, no logs (checked 20 Jul 20:30 UTC, after window) |
|
|
|
|
Cumulative spend: 381. Balance after (verified GetAccountStatus 2026-07-20): **2,257**.
|
|
|
|
**Re-estimation warning (2026-07-20):** T59 actual came in at 1.6x the estimate
|
|
(381 vs ~240). Either billing is on wall-clock session time (Time Used matched
|
|
start-to-end, not the 180 min of exposure) or the rate card's 80/hr for T59 is
|
|
stale. Treat ALL queue estimates below as ~1.6x low until re-verified against
|
|
account/history.aspx after the next paid run. At 1.6x, the remaining queue
|
|
(~1,700 est) actually covers the full 2,257 balance nicely.
|
|
|
|
## Planned allocation (~2,600 points, adapt as scopes/weather allow)
|
|
|
|
**Phase 1, dark nights now - 23 Jul (~1,030 pts):**
|
|
- T59 NGC 6744 LRGB, 3 h, ~240 (scheduled 19 Jul)
|
|
- T32 Centaurus A LRGB, 2 h, ~292: early UK-afternoon window while it is high
|
|
- T8 Corona Australis dust complex LRGB, 2 h, ~260
|
|
- T70 (Chile) Scorpius tail / Prawn super-wide LRGB, 2 h, ~238
|
|
|
|
**Phase 2, bright nights 24 Jul - 2 Aug (~440 pts, narrowband only):**
|
|
- T59 NGC 6188 in Ha/OIII/SII 5nm, 3 h total, ~240
|
|
- T8 Ha on the Cat's Paw / War and Peace field, 1.5 h, ~195
|
|
- Plus any full-moon free promotions for clusters (cost 0, not part of the drain)
|
|
|
|
**Phase 3, dark nights 3 - 10 Aug (~1,130 pts):**
|
|
- T8 SMC + 47 Tucanae in one frame, 3 h LRGB, ~390: the signature shot, SMC well
|
|
placed in the second half of the SSO night by August
|
|
- T8 or T59 Large Magellanic Cloud attempt if it clears the elevation limits late
|
|
in the window; otherwise Tarantula on T32, 2 h, ~292
|
|
- Remainder (~450): best-of list: repeat the strongest target for more depth, or
|
|
Chile scopes (T71 106/hr, T73 224/hr) if they return from maintenance: Tarantula
|
|
and NGC 1313 preferred. Aim to land the balance under ~50 points.

|
|
| 749302 | T32 | 21 Jul | 18:50-21:50 | cena-t32.txt | ~350 (x1.6 rate, 25% moon disc.) | booked 20 Jul. EVENING slot: T32 has a 35 deg elevation floor and Cen A culminates ~17:10 before dark, sinking to 11 deg by the old 00:35 slot (which could never have run). 46% moon is up ~30 deg away: acceptable for a bright drain target. Reschedule flag AGAIN shows No despite RescheduleCheckbox=on in the POST: the flag does not stick, treat every booking as one-shot |
|
|
|
|
The T33 free runs and the T33 first-light test remain outstanding: rebook a free
|
|
T33 slot (next window: night of 22 Jul SSO, 00:05-00:50, i.e. 21 Jul ~14:05 UTC)
|
|
and investigate why the reschedule flag read "No" in the grid.
|
|
|
|
## Booking queue (blocked by the rolling 8-hour reservation allowance)

Book in order as quota frees (a session completing releases its hours). Exact

Quota position after booking 749302 (2026-07-20): held = 749230 (2h20m) +
|
|
749302 (3h) = 5h20m of the 8h allowance, ~2h40m free. Queue #2 (cra-t8, 3h,
|
|
night of 21 Jul SSO = 22 Jul 01:35 local) does NOT fit until tonight's Cen A
|
|
run completes (~11:50 UTC 21 Jul) and releases its 3h. NEXT BOOKING ROUND:
|
|
21 Jul around midday UK, book #2 cra-t8 (full 3h) plus the free T33 47 Tuc
|
|
retry (00:05-00:50, night of 22 Jul SSO). At corrected (x1.6) rates the full
|
|
remaining queue runs ~2,530 vs 2,257 balance (~270 over): once actual bills
|
|
for Cen A and CrA land, trim Phase 3 (shorten Tarantula #6 or the SMC slot)
|
|
to land the balance near zero.
|
|
|
|
Substitution rules: if T71 returns to service, move #2 and #7 to T71 (faster
|
|
f/2.8 optics, cheaper 106 pts/hr; re-cut the plans for 1.55"/px). If T70's
|
|
server returns, book #7 as-is. Check the go.itelescope.net status line before
|
|
each booking round. After #6, allocate the remaining balance (~450 pts) to a
|
|
final deep session on the best-performing scope, sized to land under 50 pts.
|
|
|
|
**10 Aug: verify balance is near zero, download ALL data from data.itelescope.net,
|
|
then (with explicit user confirmation) cancel via MyAccount/Cancel.aspx.**
|
|
|
|
## Operational notes
|
|
|
|
- Sessions are now RESERVED, not walk-in: upload the plan to the scope, then book
|
|
it at reservations.itelescope.net with the plan attached (procedure in
|
|
plans/README.md); iTelescope auto-starts the plan at reservation start and the
|
|
reschedule flag retries weather losses. Claude sessions monitor rather than
|
|
drive. T59 moon discount correction: 0% until 21 Jul, 25% from 22 Jul.
|
|
- Cron jobs live only in an open Claude session; if a day's session has no live
|
|
session to fire it, the user prompts "run today's drain session" and any session
|
|
picks it up from this file plus state/TODO.md.
|
|
- Bad-data protection: iTelescope refunds points for weather-ruined runs on
|
|
request; check each session's images before marking the ledger final.
|
|
- Final data sweep before cancellation: everything on data.itelescope.net AND the
|
|
per-scope /images/qisback/ folders.
