My Astrophotography Activities

Software Architecture and Engineering

My day job is focused in creating software.  Mostly leaning on the applications where customers and client can use our products.  It’s nice to see that a lot of people have actually touched the product I helped developed.  Okay so as I accumulate experience behind me, getting more structured in my thought process in creating an application, there are things that I left behind and somewhat rusty but those things are essential and fundamental to what I do.  I guess it’s time to get dirty again, roll my sleeves and just get things done.

Well I guess to do that is create something meaningful at first, and that’s why I decided to write something about creating a Web Application using React, GraphQL, Apollo and probably to use that as my next generation web site.

Let’s see how it goes, you can follow the updates on my github page

The Tulip Nebula

I had a lot of problem capturing the Tulip Nebula because of some issues with probably my mount, my alignment, my guider or simple because of the weather.  It was very windy in the past few days and couldn’t control.  Anyway, I tossed half of my data worth around 5 hours of exposure.

Also I replaced my Orion OIII Filter and used an Astronomik OIII 12nm CCD Filter.  It looked better than the Orion as it is causing same halo on my images.
