Description

This was a test image for a camera I just purchased mainly for travel, the ASI2600MC Duo. As much as I'd love to carry all my astro gear (filters, rotator, etc) with me on trips, luggage space is at a premium when traveling with the family. The simplicity of a OSC camera with a built-in guider was too appealing. This camera will live on my AP Stowaway.

Rather than do the usual unguided imaging run after creating a model, I wanted to see what I could get with only a rough polar alignment (a single pass with Polemaster), no model, and a 4nm dualband filter in front of the guider. I'm impressed! PHD2 was able to find stars to guide at 1s exposure (note this is with a 4nm filter and at f/7), but I chose to guide at 4s. I suspect that with a proper model and "bump" guiding, results will be even better. After I dial in tilt, I'll also need to test the Duo guider with my 0.8x reducer (f/5.3), which has a smaller image circle - at 40mm - but should be even easier to find suitable stars to guide with.

I suppose now I need to go shopping for a lightweight/portable mount. The Rainbow Astro RST-135E seems to have everything I want, except the price!

Taken in my backyard in very light polluted East London, UK.
