pollen / humidity
My main issue has always been humidity and rapidly changing temps. If your detached garage is well insulated and doesn’t seen moist, covering your scope with possibly a mirror heater or dehumidifier m

Nova Cassiopeia 2021
Thanks Myron! Hope to see it on next clear night. By the way, I donated a older SBIG self-guiding spectrograph to BAS a month or so ago. If you want it, you may be able to contact Fred to ask for it.

Eyepieces
depends on many things (scope, observing interests, etc.), but I will take a stab in the dark and say a 13mm (many great options out there), of the same "class" as your 20. ---------------------------

hydrogen alpha horsehead from tonight
Hello Don: For the horsehead, I was shooting 5 min subs in Ha light for a total time of about 2 hr 40 min. The narrowband filters are very narrow and only let in a small fraction of the total spectrum

Thanks for the galaxy and glob pics Myron. Time to switch my scope on my mount for one with a bit more focal length (probably my 9-1/4 f/10 until my Hyperion 12.5 f/8 comes back from the spa). Regards

soul and rosette in Halpha from last night
It will be interesting as I have never combined images from different filters before. Time to figure out next step with PixInsight!
