I was using my mono SS III CCD with the Luminous filter amd william optics 66mm APO After I did a 2 star alignment to the West sky I followed that with a calibration star and then out of alignment. I did a goto to M42 to test the goto accuracy and M42 ended up in the cross hair. I then did a goto to NGC 2359 and the mount turned to the East I then powered down the mount checked the transit time of NGC 2359 and found It was at 20:41 and it was only 20:20 I wanted to start the session West of the Meridian.. I had a few minute so I calibrated the PHD guide system At around 20:45 I redid the 2 star alignment to the West with a single calibration star. I did a goto to M42 It was centered And then a SYNC to Sirius somewhat near Thor's Helmet (NGC 2359) Then a goto to NGC 2359. I tried a 3 minute sub and then a 5 minute sub and got no Helmet. Packed up and went in defeated... The only thing I can think of was that the atmosphere was particulate or moisture filled Post Extras:       mak7 sage Reged: 09/29/07 Loc: light polluted Phoenix AZ Re: CG-5 ASGT Cant find NGC 2359 [Re: Gregk]       #4438226 - 03/09/11 06:54 PM Edit   Reply   Quote Quick Reply   Hi Greg, I have a hard enough time seeing it in my 140. Were you imaging with your 80 and guiding with the 66 ? It is a pretty deep object and takes mutiple 10 minute subs to get much in the TEC 140. Don't give up, insure your goto accuracy and give it lots more time. It will still be pretty small in the FOV of the 80, forget the 66.

What is the focal length on the WO 66 ? Looks about like my 550mm WO 80mm FD in size perspective. I'm pretty sure my AT65EDQ would present a smaller image of the helmet itself.
