Equipment
The Equipment window allows you to enter data that describe your telescopes, cameras and the like. The selected items are used to calculate a visibility model for each object in an observing plan.
The window includes an information pane at the top summarizing the selected combination of equipment. If a camera is selected in the equipment panels, the information pane shows Imaging Setup Summary and details appropriate for imaging; otherwise, the information pane shows Visual Setup Summary and details appropriate for visual observing. The summary panel is followed by collapsible panels for each type of equipment. Tap the down arrow at the right of the panel to expand its contents or the up arrow to collapse its contents.
Digital Setting Circles
Digital Setting Circles allows you to configure a DSC device for wireless PushTo operation.
- Select one of the supported DSC (PushTo) devices, or None to disable the feature. Supported devices include Argo Navis, Nexus DSC and Sky Commander. PushTo operation requires a Wi-Fi connection to the DSC.
- Enter the IP address and the TCP Port number for the wireless connection. These values are described in the documentation for your DSC or Wi-Fi device.
- Tap Test to verify that the settings are correct. Note that the DSC should be attached to the wireless network for Test to succeed.
Instruments, Eyepieces, Cameras, Filters, Barlows, Observers
These panels display items currently defined in the database. Items may be defined in Deep-Sky Planner Desktop Edition and transferred to the Mobile Edition using the Cloud Import feature. Items may also be downloaded from the Deep-Sky Planner Community.
You can delete an item from an equipment panel by swiping an item (left or right) and tapping the Delete button. If a confirmation box is shown, you must tap Yes to delete the item. Note that the 'None' and 'Unspecified' items cannot be deleted.
- Instruments includes names of telescopes, binoculars and camera lenses. Select None for naked-eye observing.
- Cameras includes all camera types, like DSLR, CCD etc. Select None for visual observation.
- Eyepieces includes all optical eyepieces.
- Filters includes visual or photographic filters.
- Barlows includes magnification extenders and reducers.
- Observers includes specific people, or Unspecified if no person is selected.
Visual Setup Summary
- Magnification is the computed total magnification of the optical system. This applies to visual combinations of equipment (no camera selected.)
- True FoV is the computed circular field of view provided by the optical system.
- Resolution is the computed resolving power of the telescope or binocular instrument in arcseconds.
- Exit Pupil is the diameter in millimeters of the light pencil emerging from the optical system.
- Eye Pupil is the diameter in millimeters of the observer's fully dark-adapted eye pupil.
- Pass Band describes the optical wavelengths in nanometers delivered through a filter by the optical system. If the pass band includes any well-known emission lines (such as hydrogen alpha at 656 nanometers), it is noted.
Imaging Setup Summary
- Image Scale is the computed normalized area of sky captured by a single pixel on a CCD or CMOS detector. Sky area is normalized to represent a square pixel whether the physical detector has square pixels or not. This applies to imaging combinations of equipment (CCD/CMOS camera selected.)
- FoV is the computed rectangular field of view of a photographic combination of equipment (CCD/CMOS or film camera selected.)
- Resolution is the computed resolving power of the telescope or photographic lens in arcseconds.
- Pass Band describes the optical wavelengths in nanometers delivered through a filter by the optical system. If the pass band includes any well-known emission lines (such as hydrogen alpha at 656 nanometers), it is noted.
