Good Advice for for the (Starry) Night Life

Hello again. Welcome back to another instalment of the DAA blog!
I’ve been quite busy and quite active this summer when it comes to photography. I’ve been out shooting almost every weekend where the weather cooperates. Anyone who’s been following me on Facebook, Flickr, and Twitter will know I’ve published a lot of pics over the last few months. I’m even beginning to think that now I no longer can call myself a novice at astrophotography. I believe I’ve stepped into the the “intermediate” category. I’m still learning, but I’m at a stage now where I’m experienced enough to know what I need to do, what not to do, and understand how my different settings on my camera will affect my final product.

As astronomers and astrophotographers, we’re all aware of dew control solutions. The cheapest solution for Cassegrain-style scopes and comes in the form of a dew shield. It extends past the corrector plate and helps mitigate dew formation. However, that doesn’t help much when pointing straight up. And even when shooting lower to the horizon, a dew shield will at most buy you a bit of time.

The most reliable dew control is using dew heaters. But it’s not cheap. Heating strips for most telescopes will set you back at least $100, and you still need to buy the controller, which can range anywhere form cheap 2-channel controllers for $100, to multi-channel for several hundred dollars. All serious astronomers will likely get a real dew control system at some point. But for someone just starting out and in need of a lot of gear, forking out $200 plus buying a heavy-duty battery that can handle the stress of dew heaters is not necessarily feasible.
