Heart Nebula (IC 1805) - Session 4

Goal: dust to dawn imaging for IC 1805.  

Started with the mount already in the yard using the same alignment from 10/6.  Re-mounted the ST80 telescope & started Indi @ 9pm (with IC 1805 still a bit too low).  Guiding RMS in the internal guider in Indi after 9 minutes of guiding: 2" (and dropping to 1.3).

9:39pm:  With significant clouds, guiding frequently interrupted... but restarts as the sky clears.  

12:08am: With 44 images collected so far in this session, copied #44 over to examine in Picasa for focus & exposure.  Focus: good.  Exposure -- noted the capture was at ISO100 (used for flats collected on 10/3).  Updated to ISO 1600 and restarted the job.  New darks will have to be collected for 180s at ISO100.  

7:48am:  81 lights captured in total through 4:23am. Job ran to completion with mount parked at the completion time of 4:45am.

Markarian's Chain

Image
Started a mult-session collection on 03/26 (52) and continuing on 04/15 (47), 04/16 (109) and 04/19 (~20) against Markarian's chain  with the venerable Orion ST80 using the generic dual narrow-band filter , clear Astronomik EOS clip-in filter (for consistent focusing with the EOS CLS clip-in filter) and Canon T3I (astro modded for Ha sensitivity).  180s collections used for each (except for 3/26 at 300s) and flats collected against morning blue sky when needed based on re-focusing (03/26, 04/16).  Canon configured with UTC time.  Based this collection in Kstars/Ekos/Indi by centering on  NGC 4438 . For this processing, utilized both 60x180s and 30x300s darks as well as 130 bias (all at ISO1600) frames for calibration.    Collection notes from 04/19:   Ran entirely on the Odroid XU4 via remote desktop protocol (rdesktop client with compression) to simulate a remote location and provide some robustness for network / wifi drop-outs. ...

Great North American Eclipse

Image
4/8/2024 On Akron OH captured a time-lapse of short exposures through Baeder solar film through the venerable Orion Short Tube 80 with the Svbony 405cc using AstroDMx Capture until totality. Results were great considering the high level cirrus clouds.  After light editing in digikam, found some evidence of corona!

M94 and M106

Image
 3/7/24 -- first moonless, cloudless night with workable temps.  Attempting to capture M94 high in the north sky from the Meade LX10 EMC with UV/IR cut filter, Meade 0.63 focal reducer and the Svbony 405cc camera.  Set camera temp to 0C and using 0 gain and 0 offset. Telescopius simulator result for M94 using the SCT with the 0.63 focal reducer and the SV405CC camera. Telescopius M95 altitude plot for 03/07/24. Cleardarksky forecast for 3/7/24 for Montgomery County showing fairly clear skies and reasonable seeing expected after midnight. Meteoblue forecast for 03/07/2024 for Silver Spring illustrating clear skies expected for the evening. Before mounting the OTA and counterweights, checked the mount as level and utilized the polar scope (due to a clear view of Polaris through the backyard tree -- a rarity).  Adjusted the altitude up slightly and did a sanity check to ensure ~39 degrees. Initial alignment measured with PHD2 from the Odroid was ~ -11 after several minu...
