All datasets acquired with Moana from DSO (Dark Sky remote Observatory), near Fort Davis, TX, USA.
The potential of what can be achieved on Moana’s Data with is showcased here.
Moana’s updates here. Or the eventful life of a remote telescope in the Davis Mountains of West Texas.

Various tests and endeavors not to be taken too seriously. Like doing planetary imaging with a scope optimized for deep sky, failures with interesting lessons, etc…

- Difficulties, defects and disappointment.
About the data:
The files have been curated (PixInsight SubFrame Selector working in conjunction with this script, and visual QC) then stripped of private information (like observatory exact coordinates) with this script. The frames are otherwise raw from acquisition.
The image parameters are as follow:
Resolution: 0.591 arcsec/px
Field of view: 45′ x 35′
Focal distance: 1325 mm
Pixel size: 3.80 um
Aperture: 254mm -10 inches
F number: f/5.3
Guiding: Off Axis Guider with QHY 5L2M
The camera is currently an ASI 1600MM, soon to be replaced by a QHY268M. The mount is an AP1100 GTO.
For imagery I use mostly gain 90 and 5mn exposure for Narrow Band, between 1 and 5mn exposure for RBG. 5mn seems to be a good compromise between minimizing the amount of disk used each night, collecting enough light, but also be short enough to avoid too many satellite trails, cloud interference or a guiding mishap ruining the frame.
For photometry, given the wide variety of target brightness, anything goes (gain, exposure time and filter) to achieve the correct exposure.
In all cases gain and exposure shall be verified from the fits header, to ensure the use of the correct calibration masters.
The filters are Baader CMOS-Optimized RGB-R Bandpass Filter and Baader 6.5nm Narrowband Ha, OIII and SII. All 36mm round, unmounted.
