Planetary Alignment Event on March 2018

Posted on Updated on

Next astronomical event will be the alignment between the planetary objects Saturn, Mars, Jupiter, Moon and the star Antares.

Take the chance to do a wide field photography or study the planets through either telescopes or binoculars to try and see their features.

The event will happen on March 7th, 2018 at 4 AM (PST) and can also be observable on the 8th of March as well.

Below I’ve labeled all the celestial objects that will line up.

  1. Saturn
  2. Mars
  3. Antares
  4. Jupiter
  5. Moon

A long cold and humid night but it was worth it

Posted on Updated on

I went off just outside Mather airport and started to set my telescope up. Unfortunately I didn’t have both of my telescopes with me so I couldn’t broadcast live. With me I had my  William Optics Megrez 72 APO.

The night was very humid, cold but there wasn’t any wind at all. As the eclipse was progressing the moon was turning more and more red/orange.

  • ISO-100 and 200 with Canon EOS 50D
  • Exposure Time: See each image for details
  • Telescope: William Optics Megrez 72mm f/6 Doublet Apo Refractor
  • Mount: Sky Watcher EQ6 Pro
  • Date/Time: 1/31/2018, 3:03 to 5:42 AM (PST)
  • File Format: RAW (CR2)
  • Weather Conditions: Cloud Cover from 40% to 10%, Transparency below average, seeing average 3/5, darkness 4.4 for 0.2 hours and magnitude 4.3 at full eclipse.
  • Wind: 6 to 11 mph (Forecast), 0 to 5 mph (Actual)
  • Humidity: 85% to 90%
  • Temperature: 41° to 50° F (5° to 10° C)

The humidity was the major disrupting factor this night. I had to bring in both telescope and camera twice and put the car heater on to get rid the moisture that was on the lenses causing the images to get worse over time. Unfortunately my telescopes are not equipped with a dew heater so over time they accumulate condensation from the surrounding air.

Despite that set back the night was remarkably beautiful and quiet. Only the airfield lights and street lights kept shining in the distant background. A few curious bypassing cars stopped to see what I was doing in the darkness and took the chance to look at the spectacle themselves. I must say they were very considerate and turned off their beams to not blind me which I appreciated lots. Thank you!

The results are presented below,

To work with lunar eclipse exposure times you can use the following formula in your preparations:

CodeCogsEqn

Where

  • t = exposure time
  • f = focal ratio
  • Q = lunar brightness value
  • I = ISO #

If you don’t know the focal ratio of your telescope/camera lens you can find that out by calculating f = focal length / aperture. Lunar brightness can be determined through the Danjon scale. More information on exposures and lunar brightness visit Mr Eclipse website here. Fred Espenak’s table breaks it down very straight forward and simple right here.

Sky-Watcher SynGuider Firmware Update

Posted on Updated on

I wrote a tutorial for updating the firmware on a Sky-Watcher SynGuider. If you have more questions or feedback please feel free to get in touch with me. I hope this comes to use and helps out people to understand the steps needed for the updates.

Casing for telescope mounts

Posted on Updated on

I must say this was one of the best gifts I got for my birthday by my wife. It is a Condition 1 – Airtight/Watertight Case #839 with Foam. I absolutely needed one for my EQ6 Pro mount! For years I’ve been transporting and wrapping this mount in bed sheets and thick bed covers to provide safe transportation to and from my observation sites.

The mount was also transferred by sea all the way from Sweden intact. I had to pay lots for insurance so that all optics could be replaced if something happened.

This is a-must-have if you don’t know how to provide a safe casing for your telescope mounts that are originally shipped inside cardboard boxes from vendors.

My wife got this case from Amazon for just $93.60 ($103.37 if you’re not an Amazon Prime customer). Needless to say, this is just as nice as a Pelican case without the Pelican price. A real Pelican case would cost nearly double the price $176.28 for an equivalent type of case.

The interior dimensions for the Condition 1 case are, 21.91 x 16.96 x 8.41 inches.

So a big thank you goes to wifey for being very thoughtful about my hobby!

Birthday and gifts

Posted on Updated on

On my birthday my beloved wife made me the most amazing present an astrophotographer could wish for. She took the composite image of the Great American Eclipse in Oregon last summer, printed it out on a 16 x 20 inches poster and finally framed it! Now it’ll decorate our wall to remind us of an amazing experience from our solar eclipse trip to Corvallis, OR.

Thank you my love!
