Orion skyquest finder scope alignment

I got my orion skyquest XT6 telescope from craigslist and on first good day of viewing I was able to see moon craters and saturn but  even though I would see the moon in cross hair intersection of finder scope I will have to literally spend 1-2 mins trying to bring it in the main eyepiece. And man I was frustrated as moon is still big but saturn took me almost 5 mins to bring it in eyepiece. Something was not right and I remembered the owner had said to collimate the telescope. So I used this youtube video http://www.youtube.com/watch?v=YAVGcGEBmCE  to collimate the telescope next day and again in the night same frustration something wasnt right.

So I remembered that in order to  bring it home I had to disassemble the finder scope, tube and base in order to transfer it safely in my car and when putting it back I had tightened some screws on the finder scope and voila that was it.  I read the manual it seems that as shown in the image the finder scope mirror need to be aligned to be in parallel to the  main mirror in the scope.  Thos two black screws in the image are used to move the scope left and right and towards and away from the scope.  So I took the scope out in the day light and pointed it  towards the street and put the 25mm eyepiece in the main scope. then I saw the top of a house in the finder scope and then in eyepiece. I kept tweaking the screws till I can see the exact object in finder scope cross hair intersection in the main eyepiece.  I repeated the same process with 10mm eyepiece.

And boy in the night I could locate the saturn or moon in finder scope cross hair and then it was dead centre in the main scope.

Next task is to see Jupiter and mars.

What a rocky start to labor day weekend

Woke up by earthquake at 7:00 AM in morning and then couldn't get to sleep. I took a bath, made my tea and started checking emails and saw that after last night deployment three storage node out of 100s of nodes were running into Full GC. What was special about the 3 nodes was that each one was in a different Data centre but it was named same app02.  This got me curious I asked the node to be taken out of rotation and take a heap dump.  Yesterday night a new release has happened and I had upgraded spymemcached library version as new relic now natively supports instrumentation on it so it was a suspect. And the hunch was a bullseye, the heap dump clearly showed it taking 1.3G and full GCs were taking 6 sec but not claiming anything.



I have a quartz job in each jvm that takes a thread dump every 5 minutes and saves last 300 of them, checking few of them quickly showed a common thread among all 3 data centres. It seems there was a long running job that was trying to replicate pending…

Email slavery

It seems I have become an EmailSlave. The first half of the day is spent in just answering to emails. There are so many emails where I am copied but I need not be. There are many emails  where its a 1-2 page email and somewhere down someone says @KP please answer this.  So it seems daily my work schedule is:
Signin to newrelic and check anomalies for 15 min. Check emails related production exception report and yes there are a ton of these report daily. Need a better tool here as this model is not scalable. I need to reduce the incoming data at me to only see relevant data like what newrelic does. May be I need to create a webapp out of these emails.Check emails for next few minutes before team callsDo team callsThen again back to checking emails until a I have taken a best shot at answering everyone waiting for my reply.Attend team meetings on Tue/Thu
Being an architect and coder at heart I don't feel satisfied at end of the day if there is nothing tangible getting done at the end.…
