Home Observatory — Pennsylvania

FIELD NOTES

Date: 23 August, 2026.

Instruments Deployed: Four Eyes, Spectral Series

Target(s): NGC 6960, Sharpless 157

Conditions: Clear Skies, Waxing Gibbous Moon, High Humidity.

NIGHTFALL

This night was the first clear night at home than I’ve had in awhile. Despite the moon being high in the sky I decided I could work around it. Four Eyes came out and this was the first night I was going to drop the filters in each one. Dual l-eXtremes, and l-eNhance, and an l-sYnergy filter wouldn’t care about the moon being out. And one half of the Spectral Series made it outside for some commissioning tests. That system has their own built in moon mitigation so I was also not concerned. (Unfortunately, more information on the Spectral Series will not be forthcoming—until it is unleashed publicly.) The night was primed, the scopes were plugged in and humming, and I was ready to buckle down to a full session of Four Eyes signal tsunami. The night had other plans…

THE OBSERVATION

I decided to train Four Eyes onto the Veil Nebula. With all that dual narrowband power being compressed by f/2 imaging trains I thought it would be a great night to capture lovely wispy Ha and OIII filaments. This one turned into a challenge! Right of the bat, I encountered trouble with the signal. Having not set this survey system up since Cherry Springs; I forgot to get it back into station mode on my home wifi. Since I was planning on leaving it out overnight and just going to bed I needed to get that done but there was clear sky to take advantage of!  I bulled on ahead with an autofocus routine that took entirely too long. One Eye got it right away (l-eNhance).  The other three filters took absolutely forever the focus point for wide open no filter was way off for the dual narrowband filters.

As if that wasn’t difficult enough the signal kept dropping out during the Autorun I had set up. Which made no sense at all since I was right next to the mount… Ugh. To top it all off the Spectral Series commissioning work I had planned that night only half worked as well. After all the frustration I decided to call it a night.

FROM THE FIELD

If there’s one thing in this hobby I’ve learned it’s — persistence pays off. Nights like this come with the territory. Technical difficulties happen, focusers simply won’t work, wifi signal drops, optics may dew up.  The important takeaway from this is that you keep going. The next night you take it out, you may have figured out why it happened and you fix it. The lessons from that particular night were to make sure the station mode is hooked up to the house router instead of being on my field router from a star party weeks ago. Having it on the much stronger house wifi rather than the small ones off the ASIairs would have helped tremendously. Also, now that I finally found focus for those filters the next time I go out will be a much quicker set up. The very few subs I was able to see of the Veil looked pretty amazing though. Four Eyes really is an industrial-scale photon machine, so the next shot at the Veil will actually produce some results.
