  1. Hi SGL members! As I'm moving to 2" filters I wish to sell my 1.25" mounted filter setup. This setup consist of a kit of Baader LRGB as seen here for example: https://www.teleskop-express.de/shop/product_info.php/language/en/info/p563_Baader-LRGB-CCD-Filtersatz-1-25----Interferenzfilter---4-Filter.html @268 Euros plus the piece de resistance, the Astrodon 3nm ones; Ha, SII, OIII. New they are 608 Euros a pop.... Example: https://www.teleskop-express.de/shop/product_info.php/info/p5153_Astrodon-1-25--Narrowband-Filter-H-Alpha-3nm-mounted.html I will part with the LRGB set for £150 and the Astrodons for £450 each of £1200 for the lot of three. That is effectively most of the haggling done already. These filters rendered me six AAPODs in one year alone, and that was with mediocre OTAs and substandard processing skills... I can accept PayPal, UK or French, UK or European Bank transfer, I can ship from the UK or France, no problem as I tend to go back and fourth. Let's say £7.50 per filter shipping cost for insurance purposes. They will also be available for pickup in London shortly. The filters have never been cleaned or wiped. They have lived in Atik Filter wheels as long as I had them. Below: LRGB set to the left, Astrodons to the right. /Jesper PS There might be an ATIK EFW2 up for grabs too once these are gone ;-)
  2. Sadly, this project is currently stalled by the atrocious weather but at least I have had one uninterrupted night of imaging to start the ball rolling! I'm aiming for a bi-colour rendition combining Ha and OIII data at 3nm. I have a lot of data capture to go but it's a fair start. Image Stats Mount: Mesu 200 Telescope: Sky-Watcher Esprit 150 ED Pro CCD Camera: QSI 683 WSG-8 Sampling: 1.04”/pixel Guiding: OAG/LodeStar Filter: Astrodon 3nm Ha Exposure: 10 x 1800 sec Date: 31/07/17 Calibration: Bias, Darks & Flats Full Frame Cropped Frame
  3. Damn you Astrosweden for having a Black Friday sale!! I had previously told myself that I could never justify the cost of 3nm Astrodon even if they are great. But how can I resist when they are half price? 355 Euros for a 1.25" 3nm Astrodon Ha-filter was just too good to miss. NO more Christmas gifts for me now...
  4. I recently bought an Astrodon 3nm Ha filter for my new mono camera. It was half price so I couldn´t resist and 2 nights ago I got to try it for the first time. Yep, it delivers! The image was a breeze to edit. The only thing I have to fix is a backfocus issue (I think) that gives me elongated stars in the corners. So, this is 44*5 minutes with the ASI 1600MM-Cool and the Astrodon 3nm hooked up to a Samyang 135mm lens @f/2.8. My guider malfunctioned so I thank the short focal length for allowing me to shoot 5 minute subs Can´t wait to catch some OIII to make a bicolour version! Oh, I forgot - no darks, flats or bias frames used since I haven´t made them yet
