clear filter) would affect the system's performance at f/2.2.
So, a filter should always be installed in the drawer, either the
included clear filter, the optional Nebula Filter, or some other
astronomical imaging filter you wish to use.
To change the filter, unthread the clear filter from the drawer,
and thread in the Nebula Filter. Make sure to put the clear filter
in a safe place! Reinstall the filter drawer into Origin, orienting
it as shown in Figure 15. When the magnets connect to the
drawer, you'll feel it "click" into place. Finally, reinstall the lens
shade onto Origin.
Now, go back to the app and indicate that you have changed
filters in the pop-up window. The app will ask if you want to re-
autofocus, which you should do. Now, you are ready to image
with the Nebula Filter. The app will also update the default
settings, using 15-second sub-exposures at ISO 200 for the
best performance with the filter. Remember, you can always
change the camera settings manually.
When you are done using the Nebula Filter, either at the end of
the night or if you want to resume imaging broadband objects,
reinstall the clear filter. Before doing this, press the Nebula
Filter button in the lower left corner of the Camera View. The
app will direct you to reinstall the clear filter. Then press OK.
After reinstalling the filter and pressing OK, you'll be asked if
you would like to autofocus again. Choose this option. After
autofocusing is complete, you're ready to resume imaging.
If you disconnect from Origin with the Nebula Filter installed,
Origin will automatically ask you if the Nebula Filter is still
installed when you reconnect.
Using Other Filters
You can use any appropriate third-party astroimaging filters
in 1.25" or 2" format with your Origin. The maximum shoulder
height for the filter to fit in the drawer is 8mm, which should
accommodate most filters.
To install third-party 1.25" filters, follow the same instructions
for the Nebula Filter for Origin. For 2" filters, in addition to
removing the clear filter, you also need to remove the 1.25"
filter adapter ring, which is the part that the 1.25" filters thread
into (Figure 16). Grasp the knurled edge of the ring with your
fingers and rotate it counterclockwise. Once you remove the
ring, you'll see the 2" filter threads.
When using other filters, we recommend pressing the clear

filter button, which will instruct you to remove the clear filter,
and then install the "Nebula Filter, " which, in this case, can
be any filter you choose. The app will ask if you want to re-
autofocus, which you should do. Now, you are ready to image
with your filter. The app will update the default settings using
15-second sub-exposures at ISO 200. Remember, you can
always change the camera settings manually.
If your filter's glass is much thicker than 2.0mm, it may put the
focus point out of range of the autofocusing routine. A pop-
up will appear. Use the manual focus controls to get stars
reasonably in focus, then try pressing the AutoFocus button
again.
Also, depending on the filter, AI image processing may not
provide the best results; you may want to process the raw
images manually. You can turn off some (or all) AI image
processing under Menu>Settings>Advanced.
