Observing Session : 30, September.

I’m quite gobsmacked at the number of clear nights I’ve had this month. At least the four night gap since the last session has enabled me to catch up on some¬†sleep ūüôā Despite a little bit of Moon, tonight’s sky was pretty much perfect. I’ve just noticed the humidity was down to 72%, a figure I’ve not seen since earlier in the year in April.   Date: ¬†30/09/2015¬†¬†Time: ¬†19:54 ‚Äď 22:33 UT Seeing: I Perfectly¬†Stable,¬†Transparency:…


Lunar Eclipse: 28, September

I’ve finally managed to get round to processing all of the images that I took of the Lunar Eclipse last Monday. This is the second full eclipse that I’ve seen, but the first of which I intended to take lots of images. Nothing much to say about these, but I decided to use my Nikon D80 fitted to the TMB80. The big RC would have been nice, but with the D80’s chip, I would have…


Observing Session: 26, September

Bloody typical. More clear skies than I know what to do with, and what do we now have now – A full on Moon! Having decided that anything galactic or nebulous was going to be a waste of time, I set Skytools 3 the task of finding me some open clusters up near the Zenith that would be suitable for observation. As my Collinder observing programme has been quiet of late, I set the search…


A New Toy: 18, September

…..and yet another clear night in September. At this rate I’m going to be knackered. I’ve also had so many clear nights since this session that I’m way behind on writing up all the observing logs that are now accumulating. ¬†I think I can say that September¬†has been my most productive month EVER. The main reason for opening up was to try a newly acquired toy for the DBO2 I’ve been getting a little fed…


Observing Session: 9, September

Three observing sessions in under a week – it’s been a while since I had¬†one of those. The wind was a little too high to safely open up the DBO, so I dragged the Baby RC out for some star hopping. I’m so glad I don’t have a Cassegrain design any more, ¬†as within 15mins, dew was dripping off the scope. A corrector plate would have dewed up almost immediately! Dealing with dew requires yet…


Observing Session: 6, September

Wow. two clear nights in a row. ¬†Transparency not too hot with the murk climbing up to about 20 degrees from the horizon. Still had trouble seeing C17, but at least a small proportion of C18 revealed itself. Session Stats Date: ¬†06/09/2015¬†¬†Time: ¬†20:49 ‚Äď 22:49 UT Seeing: II¬†Mostly¬†Stable,¬†Transparency: III Mostly¬†Clear,¬†Temp:10.0c, ¬†Pressure: 1025mb,¬†Humidity: 84%,¬†Dew Point: 7.4 ,¬†Wind: 2mph,¬†SQM: 18.5 mags/arcsecond,¬†NELM: 5.3mag   NCG891, C23 Not Seen.¬†I checked carefully that I had identified the star field. NCG1036,…


Non Observing Session: 5, September

Well this little session proved to be a bit of a damp squib. Scope Nights said there would be 50% plus cloud all evening, so we invited some friends round for dinner. A very nice evening from that point of view, where the ‘Vin Rouge’ flowed in reasonable moderation. As they were departing at about 11:00, it was pointed out that the sky was as clear as a bell and the Milky way was stretching…


The Dog’s Cahunas

With the complete domination of highly accurate and very detailed¬†digital Star Atlases around, you would have thought that a) there would be no need for hard copy printed versions any more, ¬†and b) Not another NEW hard copy atlas. Well that’s what I thought until I saw Interstellarium’s new Desktop Edition Atlas. Upon opening it, you realise that it very closely duplicates the information in Willman Bell’s Uranometria 2000.0 atlas. Both have a similar map…
