First session with Asiair Plus

First session with Asiair Plus

I’ve been pondering for weeks whether to buy an Asiair. I really like sitting outside with my laptop directly connected to the camera and sharpcap for livestacking but it’s getting cold and there’s something about observing the skies from my warm home that is hard to beat.

The main alternatives are:

  • A raspberry pi
  • The asiair
  • A mini pc or laptop to which you remotely connect
  • Going all eskimo

I bought the asiair with an EQmod cable to connect directly to the mount.

So how about this Asisair? It’s small and light, which is nice and it works out of the box. Focusing, polar aligning, controling the mount, everything works. The only thing I struggle with is the wifi signal, so I had to take refuge in the laundry room to stay close to the scope. Something I’ll have to figure out because the vibrations of the washing machine made me doubt the tracking of the scope on the live view.

I will also need to start adding calibration frames to my images. Maybe it’s just me but I think I had less noise with sharpcap.

Here are a few of my livestacks. M76 or ‘the little dumbbell nebula” is the most intriguing.

Into Cassiopeia

Into Cassiopeia

My goal tonight was to hunt down a few more Messier objects. I managed to get my platesolving working but only got good accuracy in Cassiopeia for some reason. All good, it’s a wonderful place to get lost.

Deep space

Clear skies from 5 PM onwards so I made a very ambitious plan to observe multiple targets. Had some issues with polar aligning and GOTO but managed to observe:

The Crab Nebula, Orion Nebula, Bode’s Galaxy, Cigar Galaxy, Messier 103, Messier 32, and as a nice bonus: Messier 77 aka Cetus A.

The mind boggling distance of Cetus A is 47 million light-years.

Messier 33

Messier 33

I started my session with a very long polar alignment in sharpcap and aiming at random spots in the heavens with the hope of platesolving my way to glory. When finally it worked I got to capture the ethereal glow of Messier 27 and Messier 57.

I also had a long look at Triangulum (Messier 33) but didn’t manage to capture it well. My plan was to observe much longer but it got too cloudy and my platesolving started to fail again. There is a lot to say about Messier 33, but watching another galaxy like this is something very, very special.

Now that I have everything figured out with the new equipment I hope to explore many more objects. However, with Mars opposition around the corner I might take out the dob again soon.

Whilst platesolving I also got photobombed by this guy:

Testing the system

Testing the system

I had two wonderful nights with little to no clouds and managed to:

  • Align my polar scope
  • Polar align manually with my knees in the wet grass
  • Get decent tracking!
  • Give up on polar aligning manually and buy the 10 USD sharpcap pro license
  • Use sharpcap pro to polar align – this is so easy.
  • Align the scope, which was a big hit and miss
  • Making a total mess of connecting sharpcap, stellarium and synscan together to the mount
  • Confusing my scope, laptop and eventually also myself
  • Not collimating the scope resulting in horrible stars on my laptop screen

When I ordered the scope to go to Albireo, I felt some relief when I saw two little diamonds in the sky. Unfortunately those were two stars slightly west of Vulpecula. Still pretty close though.

New gear

Testing out my new EAA rig, a Skywatcher 130 PDS on a HEQ5 PRO mount.

This is what went wrong during the session:

  • Rain till 8 PM, making it necessary to set everything up late when it’s already dark and cold
  • Forgot to install the the ZWO drivers on the old imaging laptop I want to use
  • Polar alignment difficult with the northern part of the sky being cloudy
  • Underestimated the swampy nature of my grass, making it hard to level
  • The part of my garden with perfect view on Polaris is also the dog’s pooping grounds

I tried to to do some star alignments. Aldebaran was close. Betelgeuse was funny as the scope pointed to the ground.

Still very impressed with this mount. I will set up everything during the day tomorrow and play around with it.

Fall is here

Fall is here

After literally weeks with clouds and rain I finally got to set up the scope again. My plan was to capture Mars but the seeing was again not optimal – I captured a lot of data but I don’t think it will lead to anything good post processing. This was also my first session where I really had massive dew, something I need to take care of.

My goal for the next weeks is to have a look at the Triangulum Galaxy and the Crab Nebula and today I had a first few peeks with the 25 mm.

I hope to capture them with my camera at some point too, I’ve purchased a focal reducer to increase my FOV, I’m curious what I’ll manage to get.

I did capture some other nice sights. One of them is Albireo, I remember I posted about this in july after I made a picture with my phone. This one is definitely better.

I wanted to end the night with Orion but clouds made me call it a night.

Fading summer

Fading summer

I had a short but focused session last night. My initial goal was to capture Mars and Uranus with the planetary camera but the supermoon made things a bit difficult. I hope to revisit these planets later this year.

The summer triangle is slowly moving away from my usual observation sights so I’ll need to say my goodbyes soon to Vega, Deneb and Altair. New other prominent objects are showing up now, such as the lovely Pleiades.

I decided to have one last look at M57 and took an almost 4 minute exposure with the ZWO224MC.

The reward was worth the effort:

Clear sky

Clear sky

Clear, dark sky today, unfortunately on a midweek, so little time to observe.

I had a good look at the Dumbbell Nebula again and failed to find M56, a globular cluster. I did find another target though, the Blinking Planetary Nebula, with very little effort (or lots of luck, not sure).

The green disk-like form is very obvious on this grainy picture. Through the telescope it looked more blue, with an obvious blinking effect when looking at it. Very cool for a smartphone snapshot.
