UPDATE - FOLLOWING THE NEWS TONIGHT ABOUT EVERYONE BEING REQUIRED TO SELF ISOLATE , I HAVE DECIDED THAT I WILL NOT BE SELLING MY KIT UNTIL THE RISK POSED BY COVID 19 IS SIGNIFICANTLY REDUCED FOR MY ELDERLY IN-LAWS (WHO WE CARE FOR) . I WILL, HOWEVER, BE HAPPY TO TAKE THE NAMES OF ANYONE WHO MIGHT INTERESTED IN ANY OF THIS LOVELY KIT AND WILL CONTACT THEM ON A FIRST-COME, FIRST-SERVED BASIS WHEN / IF THING RETURN TO SOMETHING RESEMBLING NORMALITY.
SORRY IF THIS COMES AS A DISAPPOINTMENT TO ANYONE WHO HAS ALREADY EXPRESSED AN INTEREST.
THANKS FOR YOUR UNDERSTANDING
I've reluctantly decided to sell all of my AP kit in the hope that someone out there will be able to do this lovely kit the justice that it deserves better than I can.
I therefore have the following items for sale:
10 Micron GM1000 HPS Mount with GPS, stickstation, 2 x counterweights, remote on/off push button and pier adapter - £5000
Takahashi FSQ106ED with spacers, CA35 camera adapter, parallax tube rings, finder, dovetail (with counterweight bar) and 0.73 reducer - £4300
Atik 460ex mono - new electronics fitted by Atik in Feb 2020 - £1300
Chroma 1.25" 3nm Ha, S and Oiii filters - £1000
Chroma 1.25" LRGB filters - £320
Aurora Cloud Sensor and serial adapter - £180
Lakeside Focuser, serial adapter and 2 x motors - £230
Starlight Xpress Lodestar 1 - £240
Starlight Xpress OAG - £110
Starlight Xpress filter wheel (new electronics in 2017) and 7 x 1.25" carousel - £190
Pulsar 2.2m full height dome in Dark Green with one equipment bay with prototype ASCOM motor drive - £1800
Condensing dehumidifier - £100
Gerd Neumann Flat Panel - £80
All of this is in good condition and has spent its life in a dehumidified dome. The major items all come in their original boxes and packing.
This is all still set up in the observatory, so any potential purchaser can see it all in action if they want to.
Images taken with this kit can be seen here: https://www.flickr.com/photos/perrybarn/
I'm open to sensible offers on all this kit and I'm also open doing a deal for the whole lot as a bundle.
I'm not planning to sell anything until the mount and scope have gone - but please PM me if you're interested in anything on the list and I'll back to you on a first come -first served basis.
All items are collect from Somerset UK or plus P&P.
Payment will only be accepted via BACS and items not released until cleared.
I am wondering if anyone has a suggestion that might help me
My imaging set up is an RC reflector with an FLI proline 16803 camera and 50mm Astrodon filters (LRGB + 5nm narrow band)
I have had a string of issues...everything from my mount had mechanical problems to my telescope had issues with the mirror cell to some family distractions...but at long last I seem to have everything working with the exception of the Astrodon Ha filter.
Attached are representative 30minute subframes of the horse head and Pacman nebulae in Ha, SII, and OIII. I get similar results with different objects although for bright, broad spectrum targets like M42, I will get data from the Ha filter (much as the stars shine thru on the HH and Pacman) although even that data does not comport with other imager’s Ha images of those objects. The LRGB performance appears to be normal. My hypothesis is that this Ha filter is defective, perhaps not centered on 656.3nm
I have contacted Astrodon and exchanged a couple of emails with Cary Chleborad seeking some help. At first he claimed there was no issue because with enough manipulation some data could be extracted from the Ha. Later, when confronted with the other narrowband frames and the obvious difference to the Ha, at first he ghosted me, but when I said I would ask other imagers for help, he responded with a new position stating that because of the way the filters are made and their robust quality processes, it is impossible for the filter to be defective and therefore something else must be at issue. He does not offer a suggestion of what might be the problem, nor is he interested in having me send the filter back for evaluation. Frankly, I’m more than disappointed given the premium I paid for Astrodon filters
All that aside, and taking Cary’s position at face value, does anyone have an idea of what might cause this behavior other than the filter? In a perfect world, does anyone live in the Austin, Texas area who would be willing to try my filter one night and see what they get with their equipment?
The attached link is to the raw, uncalibrated files right off the camera. I think a simple blink process in PixInsight will show what I’m talking about.
I’m a little at my wits end, please help!
Hi all, my second attempt at imaging over multiple nights, captured 60 mins Ha and a couple of 5 mins on Oiii and Sii on Christmas evening, then added more Oii and Sii on the 30th
Total of 60 mins Ha 25 mins Sii and 30 mins Oiii
Hubble mapped - SII,Ha,OIII = R,G,B. The Oiii data was very noisy but I'm fairly happy overall, also the ZWO Oiii filter caused a massive ring around Alnitak when stretched !
Comments welcome, I know it needs more data and I will need to learn to be more patient but the year is running out 🙂
Thanks for looking and have a good 2020.
