Is anyone imaging? I have two wind monitors and one is registering 20+ mph and the other is saying less than 5mph.

Arp 303 consists of IC 564 (UGC 5230 and others), the spiral left (east) of center and IC 563 just below it. Both are approximately 275 million light-years away in Sextans. IC 561 is the odd-looking s

Hi, Is anyone imaging? Wind is all over the place. Zero for a while, then 15mph. Just wondered if anyone else is imaging. Bernard

I always like to come home and find the white Astronomy Magazine envelope in my mailbox. That always means they’ve sent me a couple of copies of the magazine because I have an image in it. The June Ga

Arp 215 (NGC 2782, UGC 4862, VV 1268 and others) is a Seyfert (I see references to a type 1 and 2) spiral located approximately 126 million light-years away in Lynx. It is suspected that the current f

This was first light with the 17" planewave with the new SBIG 16803 and AO. Turned out quite nice considering its low elevation. I used only the best Luminance frames for this object but all of the co

This is taken with a 17in Planewave telescope with SBIG 16803 from DSNM. Such an interesting FOV showing a little bit of everything. https://static1.squarespace.com/static/57e97e6ab8a79be1e7ae0ae6/t/5

Arp 225 (NGC 2655, UGC 4637, VV 1248 and others) is a Seyfert, lenticular galaxy located approximately 66 million light-years away in Camelopardalis. Luminance – 24x600s – 240 minutes – binned 1x1 RGB

Arp 210 (NGC 1569, UGC 3056 and others) is a dwarf irregular starburst galaxy located approximately 11 million light-years away in Camelopardalis. This distance makes it a member of the IC 342 / Maffe

Hi all, My UPS device is signaling frequent but almost instantaneous power failures. Comes back up almost immediately. I have my UPS set up to send me a message whenever a power glitch occurs. Are any

Howard, This is how it always was in the DGRO building, which I believe is on the same power as you. We had a $1500 ups for this reason, it kept things going. Probably not the safest power going to ou

Mark is correct...It's always been like this... I get email every time. They are brownouts not outages and they happen when people are using power tools... Opening roofs or ACs working.

Howard, I’m not seeing anything on ours and we get emails/texts when it loses power. Our power is off of the old bunkhouse so we’re on a different feed than you. Dan ---- Dan Crowson dcrowson@... Dard

Howard... I doubt anyone ever bought a batt for the ups I donated for that router... It's most likely still sitting where I left it 2 or 3 years ago. LOL.

Hi, If I have two images of M3 globular cluster taken at different times, I should be able to subtract one image from the other and be left ONLY with stars whose intensity has changed (like RR Lyrae s

Hi, This is an image of NGC3198. This is a barred spiral galaxy about 47 million light years away in the constellation Ursa Major. Comments and suggestions appreciated. http://www.azstarman.net/CDK/NG
