My First Comet Hunt/Technical Difficulties

Recommended Posts

Hayduke27    52

I went to my dark site last night for a little stargazing with a buddy and the hopes to see my first comet through a telescope (or binoculars!).  I had a few other things on my list, namely M81 and M82 and the Blue Snowball Nebula.  I headed out armed with my telescope, 3 new EPs, a new nebula filter, a new 2" dielectric diagonal, and high hopes.

We arrived and got set up, and for the first time since I've owned it my Celestron GPS unit was not working.  It was powered up, but it just didn't seem to be connecting to the telescope as the scope kept asking me to program in the time and coordinates.  I hadn't brought an alternative GPS, as I have not had this issue in the past, and so I was not able to set up my scope for GoTo or for tracking.  I spend quite a lot of time messing with it, but to no avail.

By the time I got to observing I had already messed around with the equipment for a long while and time was getting short. I took a long look at the Ring Nebula and Andromeda, then went on to look for the comet (C/2017 ASAS/SN). Supposedly it is possible to see through binoculars, but I was having trouble spotting it with either scope or binos. I know I was in the right part of the sky, but I suspect it was just dim and my newbie eyes had trouble finding it.  It is supposed to be magnitude 12 or so right now, and being new as I am to astronomy I don't know exactly how that looks in the sky.  Anyway, by the time I gave up on the comet, it was cold and I was ready to pack up. No new observations for me.

I think the comet is supposed to be most easily observable on 10/18, and I will probably try to get out again and search for it.  I also have all these new gadgets I need to get the feel for.  I really want to make some good use of this new nebula filter soon.  Thanks for reading and clear skies!

A magnitude 12 object such as a comet or face on galaxy can be very dim indeed and difficult to spot if you are new to the hobby, even if it is in principle within the grasp of your scope. If the comet is a diffuse object (which some are) the actual surface magnitude can be quite a bit less than 12.

      so the other night i was setting up my scope, and i saw the weirdest thing in the northeastern sky. it was a fast- moving, flashing(?) object about 3- 4 degrees above the horizon. it went from the northeast to the southeast in about 3 seconds, then vanished out of sight. i didn't get a picture, my camera was still in its bag and i didn't even think of taking a pic until it was gone. now, i know this sounds like a ufo, but i don't know. i doubt it is, although i hope it was. i have seen things like this before quite a few times, but none of them at night. if it really is a ufo, id put it at a 2 on the hynek scale, for those of you who know what that is. if not, google it. its interesting. aside from the unlikely prospect of a ufo, what could it be, realistically speaking??

      Hello everyone,
      It has been a while since I posted here. I was waiting for my telescope but unfortunately my friend could not bring it along from UK  Anyway since that happened I decided to continue my search for a telescope and in the meanwhile I decided to get myself a nice binocular and carry on until I get hold of a good scope. Perhaps, I could continue with a bino for some time and gain experience and then if the passion doesn't die I can get a scope. 
      Anyway, I went to a hill station where my father-in-law has a couple of flats (at a height of 6,000 feet) and so they spend every summer there. I usually go for a few nights with my wife and kids for vacation and then come back. I had noticed in previous years that the sky is a delight in the balcony of that flat if clear. However, in those days I looked up at the stars and well that was that. So this year I wasn't able to wait to go there and observe it rather than seeing it like before. 
      It mostly rained however I had two clear nights to myself and I cant tell you how lucky I was in those two nights. I enjoyed myself a lot and learnt and also thought quite a lot. I also have a couple of questions from my first night that I would like to ask in order to ascertain my understanding. Anyway, during the first night I did not have the binocular that my father-in-law has as I had forgotten about it. So I just went there and saw things and tried to make sense out of them. I knew it was a pre-night to the Perseid peak but I had no idea that I will see the shower with my naked eye and that it would be that much. I saw the shower with my boy in my lap who would point out at every flash with excitement. However, there are my questions:
      1. I saw the shower where different (shooting stars) kept coming. they were like little balls of fire having a head a trail of light following them. But then I also saw something else during the same time and it happened more than the shower. I saw little flashes of light in the sky. One after the other and there were about a dozen of them coming from the same part of the sky more or less. Those were like little tiny dots of lights igniting at a spot and then going out in a second or less. However, they did not have any trail or streak in the sky they were like little spots that would shine in a spot and then go out. what were those ???
      2. I also spotted a satellite that was a very bright and moving very fast. However, some website suggested that it was the ISS. How does one differentiate between a satellite and the ISS ? How to know what you are beholding ???
       
      It was during the next night that I remembered the binoculars. When I got them from him those were a 12x25 not that good but not bad either. So I gazed at the moon and enjoyed its majestic beauty. Seeing the moon not as a disk and as a spherical object with your own eyes have n effect on you ... it was just lovely. Then I also spotted the Cassiopeia and observed it for some time. And then in the end the last thing was the seven sisters in the Pleiades and that was mesmerising. the distinctive question mark in the sky that made me think and contemplate on many things including, on a lighter note, the fact that I observed the sky and had questions in my mind but the sky responded with a question mark telling me that there is more that there are things even they don't know of I shall be writing an article about it soon. 
      cheers,
      Sidd

      Here are two shots of Comet Johnson.  The first is a single 100 sec exposure.  The second is a stack of 20-100 sec exposures.
      I tried isolating the stack, but it never came out right, so... trails remain.
