Holoholo – A 10.1” f/4.5 Travel Telescope

Living in the islands provides excellent observing for an amateur astronomer such as myself, but there are drawbacks. I do miss the large star parties, getting together with hundreds of other observers to see other telescope setups, to learn, and to share the sky.

Thus I have made a habit of traveling to the mainland once in a while to attend one of the larger star parties. This year I will again attend Oregon Star Party. It has been a while, the last time was 2017, the year of the total solar eclipse.

Traveling from the islands to a star party makes it a challenge to bring a large telescope. Last time I borrowed an 11”, not a bad solution, it worked, but it was not my ‘scope. This time I was determined to realize a long considered idea, to build a substantially sized travel telescope. Thus Holoholo was designed and built, a 10.1” f/4.5 travel ‘scope.

Postcard from the Universe – Andromeda

So I shot M31… yet again. I admit I enjoy this target, it is just so much fun. I always think I can do a little bit better. It is color balance that has been my bugaboo lately, I have really been playing with my technique to achieve a decent color balance. Something aesthetically pleasing and something that bears at least a little resemblance to reality. I understand how objective these criteria are, but still… I try.

M39 Region

The idea is to take a photo of a bright deep sky object and the surrounding region. The result should be an impressive starfield with something bright to give the image some punctuation. This does not always work.

In the previous image, Mirfak and Mellotte 20, the idea worked pretty well. Bright stars highlight a rich Milky Way starfield in Perseus. In this next image I processed the plan did not quite work as well. The target is the bright open cluster M39. At magnitude 4.6 I thought the cluster would appear brighter against the surrounding starfield. In this case the component stars are somewhat dimmer, thus the effect is not as dramatic.

There is still a lot of material to process from OSP, we shall see what worked and what did not.
