B30

Hi All,

Got a new toy for Christmas and just waited for a clear night. Only one night so far, so have only managed a quick image of the B30 nebula in Orion.

The new toy is for processing, it’s the Straton star removal program.

Having taken only 6x5minute images in each of Red, Green, Blue and Ha, the data was stacked in Deep Sky Stacker. Next, each one was put through Fits Liberator. These master images were then all aligned in Maxim DL.

The RGB images were put through Photo Shop curves and combined then tweeked in the colour adjustments.

The Ha image was put through the new toy and had all the stars removed from it in 35 minutes (automatically of course!).

This was then put back in PS and combined in “Levels” with the RGB image. After a bit more fiddling in curves I got this result.

It sounds a long and complicated process……….IT IS!!

Anyway, for a first attempt I’m quite pleased with the result.

Crescent Nebula (SH2-105)

First attempt at imaging since the new floor was completed in the Observatory.

Focused by hand as the electric focuser is currently not working – hence not quite in focus.

This is a 7×5 minute stacked image taken through a Hydrogen Alpha filter. Telescope being a Takahashi Epsilon 180ED at f/2.8. (A brute to manually focus!) Camera; Atik 4021, cooled to -27 degrees. Guiding by PHD and all sitting on a modded EQ6.

 

Also an image of IC1318, the diffuse Hydrogen Alpha emission nebula surrounding ‘Sadr’ (upper right), the 2.2 mag star at the ‘heart’ of Cygnus the Swan.

Calendar

Hi, I know I’m an old so’n’so but is it possible to have the old calendar of the club reinstated?

I don’t own a smart phone or any of the “modern” devices on the computer, just the basic stuff so I am unable to “download” anything in the formats that  are given.

International Astronomy Show 2018 – Day One 12/10/2018: Talks & Impressions

Geoff Dryland and myself arrived early to meet Pete Hill, Ed Mann and Terry for the start of the first day of this year’s International Astronomy Show at Stoneleigh Park just south of Coventry around 4 miles beyond Warwick University. This annual show lasts two days and is located just southeast of Birmingham in the middle of the UK.

Plenty of space allows vendors to expand the area occupied by their stalls  in the display hall and to therefore display far more stuff than in some other astronomy conferences.The talks as always were great. Today we booked for all 5 speakers, thereby leaving us with limited time for looking at the vendors. I sm back here with Rhys tomorrow and he and I can then spend more time exploring the stalls.

The first talk was on creating simulations of the universe by a professor fron Nottingham. This was an unexpectedly excellent talk and even included information in free software to generate your own universe simulation on a Linux machine called Gadget – anyone can download this so let me know if you want the link. I think i am going to dowload it myself and give it a go……

The second talk was on Astrophotography. The speaker recommends Sequence Generator Pro and Straton software. He gave lots of detail on his photo processing techniques but my own lack of pre-existing knowledge of the area snd poor acoustics in the room meant most of it went over my head.

Next talk was about commercialisation and resource utilisation of space. Another really interesting and unusual topic with information that changed my perspective on the subject.

Meanwhile Ed had bought the lowest profile 2″ to 1.25″ adapter I have ever seen and Terry a Baader zoom eyepiece. Both purchases were bargains, so well done to both for spotting those!

Ed then came back with a planetarium projector of his very own…..see photo below where Terry interogates the new device…..take me to your leader!

There followed a talk on Exomars and finding life on Mars. For me this was most interesting talk of day with lots of detail on evolution of Mars over 3.8 billion years and bringing it right up to date with recent scientific papers.

The last talk of the day was another excellent discussion, this time around the solar wind.

Each talk was nearly one hour – much longer than those at Astrofest- so giving a chance to get far more under the service of a topic.

This was a great set of lectures. Definitely worth attending the conference! Only spent about 15 mins at stalls during the day and further half hour at end of day but tomorrow I am hoping to take more time to look at those with my son.

Photos below from talks and a couple vendors.
