Guiding was manual, off-axis. The lights, darks and flats were registered and stacked in DeepSkyStacker, Curves adjusted in Canon Photo Professional, and finally noise/banding reduced with Noel Carboni's tools in Photoshop Elements.

Last year I bought a new guiding eyepiece with an adjustable reticle, which makes off-axis guiding far easier. I can now usually find a guide star and put the reticle over it without moving the subject away from the centre! Previously, subjects could end up in the vignetted area around the edge if I wasn't careful. I'm still convinced guide stars are getting fainter over the years, though! Regards, and clear skies! -------------------- Mike Crowle http://www.pbase.com/mcrowle/astrophotography Meade Series 5000 ED Apo 127mm Celestron C8 SCT (1991 model) Losmandy G-11; Vixen Super Polaris Canon EOS 40D (unmodded); Philips SPC-900NC Webcam Post Extras:       Mike C sage Reged: 03/05/08 Posts: 363 Loc: Cornwall, UK Re: M33 in Triangulum [Re: wrather1]       #3398031 - 10/19/09 01:18 PM Attachment (5 downloads) Edit   Reply   Quote Quick Reply   Thanks for the comment, David. It's probably not your monitor! I always use an Astronomik CLS for deep sky subjects - although I realise they're not ideal for galaxies, I don't like a bright orange background I'd get without it. I can correct the colour balance in post-processing, but maybe I was a little too conservative in doing so in this case. This is hopefully a little better: Regards. -------------------- Mike Crowle http://www.pbase.com/mcrowle/astrophotography Meade Series 5000 ED Apo 127mm Celestron C8 SCT (1991 model) Losmandy G-11; Vixen Super Polaris Canon EOS 40D (unmodded); Philips SPC-900NC Webcam Post Extras:       Nils_Lars Post Laureate Reged: 01/04/08 Posts: 3422 Loc: Santa Cruz Mountains , CA Re: M33 in Triangulum [Re: Mike C]       #3399503 - 10/20/09 03:09 AM Edit   Reply   Quote Quick Reply   Nice work on M33 there Mike. -------------------- Erik Orion Atlas Self Hypertuned (EQMOD) Orion ED 80 Williams Optics VII reducer Celestron 8" SCT Orion Starshoot Autoguider PHD guide Canon 400D Hap Griffin Mod w/Baader filter Astronomik clip-in LP filter and 12nm Ha Stilleto CVF and Bahtinov mask Tamron 75-300mm&28-80mm lenses NexImage webcam http://www.flickr.com/photos/31986095@N05/ Post Extras:       KevinUK Vendor (DSLR-AstroMod) Reged: 08/22/07 Posts: 720 Loc: N 51'53 W 00'25 Re: M33 in Triangulum [Re: Nils_Lars]       #3401476 - 10/21/09 02:15 AM Edit   Reply   Quote Quick Reply   Nice work, tastefully processed. -------------------- DSLR AstroMod DSLR filter removal and replacement packages http://www.dslrastromod.co.uk ------------------------------- Post Extras:       Mike C sage Reged: 03/05/08 Posts: 363 Loc: Cornwall, UK Re: M33 in Triangulum [Re: KevinUK]       #3402407 - 10/21/09 03:15 PM Edit   Reply   Quote Quick Reply   Thanks Erik and Kevin ! -------------------- Mike Crowle http://www.pbase.com/mcrowle/astrophotography Meade Series 5000 ED Apo 127mm Celestron C8 SCT (1991 model) Losmandy G-11; Vixen Super Polaris Canon EOS 40D (unmodded); Philips SPC-900NC Webcam Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 14 registered and 17 anonymous users are browsing this forum.
