Paramount ME help

Bernard Miller
 

Hi,

 

I need to polar align my Paramount ME tomorrow when I am at DSNM. The T-Point polar alignment tells me I have to rotate west 6.4 clicks. I have an older ME mount that does not have “clicks”. Does anyone have any idea how far this is on the older mounts? Also, after I adjust the polar alignment, do I have to run T-Point again? If so, how many points is enough to get good polar alignment data?

 

Thanks,

 

Bernard

Re: Comet c2021 A1 Leonard

Comet C/2021 A1 Leonard will cruise between the Whale (NGC 4631) and Crowbar (NGC 4656) Galaxies the morning of 24 November.  The tail might split them on 25 November (Thanksgiving morning).  This looks like a perfect field for about a 1m focal length telescope.  The comet will be well up in the sky for two to three hours.  However, the waning gibbous moon may be an issue.

Nice color Dan. It has a vague resemblance to the Trifid.

Arp 259 - Hickson 31

Dan Crowson
 

Arp 259 (NGC 1741) appears to be in the center of a train wreck. Part of Arp’s ‘Galaxies (not classifiable as S or E) - Irregular clumps’ class, it is located approximately 186 million light-years away in Eridanus.

 

Hickson 31 consists of NGC 1741 above and another six or seven galaxies around it. All appear to be between 181 and 186 million light-years away by redshift.

 

IC 399 is the ball galaxy located below the above. Some sources include it as the seventh or ‘G’ galaxy in HCG 31.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 8x300s – 40 minutes each – binned 2x2

 

360 minutes total exposure – 6 hours

 

Imaged January 26th, September 21st and 23rd and November 13th and 14th, 2020 Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.
