What gives of the view-finder.




Hello,


After we spent the night before, water and hurricane clearing afternoon being all clear skies with seing quite acceptable and had to take this heaven that this year is more cloudy than usual in winter.
had not given any goals, because comets are not available to me at this time as he tries the flyby night 2010AL30 or whatever, as there are several questions about their nature and there are already indications that till some interplanetary probe could be venerated as the Express.
From Asteroids? not be got to see it as something more than 15 mg and as much as I try to see in the field where he ran, and that his movement is very fast.
Comets at my disposal are a few but in theory I could not see them, the P / Reinmuth (30P) theoretical Mg 14.7 and the P / Tritton (157P) to 11.9 Mg were at the time of observation in the sky at a good height, but his observation was negative.
Tonight the first thing my eyes saw was the IC 434 ( horse head) I do not filter at all with the 12 "and hiperiom 13mm (114x). The nebula can be seen instantly seeing an area darker than the surrounding bone the rest of the nebula IC434 . I try to do with the Astronomik UHC filter to see if improvement is achieved, but what you see is what you saw before hair now does not look or looks worse than before.
I address the planetary nebula NGC 20 22 of about 30 "in diameter and 12.4 Mg according GUIDE 8.0 but I get that this nebula is somewhat brighter than the Mg 12, which ensures GUIDE.
Through the search field (6.2 °) reflected on the monitor GUIDE see that in the same field are up to 5 items of interest to be seen in more detail.
Step to describe; Collinder 69 Open Cluster with nebulosity is seen around the brightest stars, is a curious group NS aligned with stars in an arc of the Mg Mg 3.5 to 7.6. You have to watch it better with a large eye since it occupies more than 1 in what I call the head of Orion.
If we move to the West in the same field in the form we with another open cluster, Dolidze 19, shabby with few stars and roam the Mg 10.
Climbing 0.5 degrees north we found a 5.7 mg star TYC 700 1015 and a nebula around Barnard : 223 that can be seen quite well.
Almost 2 ° S of the object before we find another cluster Dolidze 21 very poor and that can only be seen as stars from the mg12 to 14.
Between the middle of the two objects above and slightly to the west is a galaxy NGC 1875 of 14.6 mg. This galaxy is perfectly free to use indirect vision over a curious group of stars of the mg mg 7.4 to 8.5.
All these objects were in the field of search engine and just had to get out of the about 2.8 degrees to meet NGC 1819 of 13.5 mg look much better than the galaxy had seen before. NGC 1875.
As is necessary in these days when Mars is now almost in its opposition was forced to give a time of observation;
Directly I put 297x and it shows that even this rather low for planetary observation. Run the rear fan to see if something better picture and see that the improvement is not too much but something has improved, but I stick with the x2 barlom 8mm hiperiom gives me a total of 371X and with this increase and in good time when the atmosphere calms down I can see the few details at this time (23:00 LT) were present.
can see clearly the northern polar cap with a dark area around the cap and a little more extensive to the east of Arcadia Planitia pole.
bone In the southern polar opposite is distinguished as something its south polar cap and a somewhat wider area than the northern cap darker.
If you want to see more details of Mars have to watch these days starting at 5 am TL
And that was all it took about two hours of observation with little to move the telescope io.
