Re: Upgrading GTOCP3 "J" chip to V2 Post steps

Steven Panish
 

George,
It's been a couple years but as I recall the brief signon message on the hand controller tells you the version.  I have 4.17 and don't recall having to do anything special after upgrading to V2 in the CP3.  I don't use the handbox much so I've never upgraded it.

Re: Need help identifying Counterweight shaft stop to buy

I can confirm that the bolt size is 5/16-18. I recently replaced a broken phenolic knob with whats shown below.
Hope this helps!

Or take the shaft to Home Depot and try either their thread template or bolts from the specialty cabinet. I’ve found that strategy very useful!

NGC 4030, a seldom imaged galaxy

Geoff Smith
 

I was able to find only one amateur image of this galaxy, which is quite strange considering its size (4 arcminutes) and brightness (mag 10.6). I would have expected that its location in Virgo would have made it a target for both northern and southern imagers. So one image on IIS, none on astrobin, no reference in any of the popular "what can I image" catalogues.


The weird thing is that I imaged it in 2017 and 2018 then forgot about it and never got around to processing it. There must be some sort of conspiracy to keep it hidden.



The image is here https://www.astrobin.com/ajvnzj/

Usual equipment: AP900, Plane Wave 12.5", FLI 16803 Proline. Processed in PixInsight.



NGC 4030 is a grand design spiral galaxy in Virgo, lying about 64 million light years.
In 2007, a supernova explosion was discovered in the galaxy from images taken on February 19 from the 1 m Swope telescope at Las Campanas Observatory in Chile The progenitor was a red giant star with 8.5–16.5 times the mass of the Sun.
See an image of the supernova here https://www.iceinspace.com.au/forum/...light=ngc+4030

This was the only amateur image of NGC 4030 that I could find.


Need help identifying Counterweight shaft stop to buy

George Lutch
 

I'm trying to identify what counterweight shaft stop I need to purchase as a replacement.  It is on an AP900GTO from 2005.  The shaft is 1.875 in diameter but the stop that is supposed to fit it does not.  Any assistance would be greatly appreciated.

Re: APPM Dec Arc Model and NINA "do not sync" option

Ray Gralak
 

Hi Andrea,

In my former Paramount ME mount a sync issued by a sequencing software like NINA would result in a model
corruption.
Syncing into the model will not corrupt the pointing or tracking rate models.

Hi,
I have two question /consideration that I'd like to be validated.

In my former Paramount ME mount a sync issued by a sequencing software like NINA would result in a model
corruption.

I assume with my present Mach 2 the situation is different because:
-if using a dec arc model (my case), pointing corrections are not activated
-every sync should be treated as a recalibration, therefore the model is not affected.

So, I'd configure NINA to send sync commands to the mount.

I'd be grateful if someone can confirm.
Thanks a lot

The grease kit should have detailed instructions included.  If not, let Daleen know.  The gear mesh doc is also good.  That should be all you need.  It isn't difficult.

Re: AP1100 Play in Dec Axis #Guiding

Rouz
 

Ok I had 30 minutes of clear sky.
Fine balanced both axis made a big difference.
Ra and Dec 8x bolts very tight
Ra and Dec 3x Clutch knobs tightened with hex key.

Small test model looks promising. For the first time, both sides look similar.
I believe with a large number of points, errors should be decreased.

Lots of info on the 'net about Andromeda's Parachute, including images.

Given your image, I think Andromeda's Parachute would be easy!

Re: APPM Dec Arc Model and NINA "do not sync" option

 

Yes I think that is correct

I hadn't considered that dec arc modeling approach does not correct for all sky pointing, good observation

Re: Challenge object: Tiny faint galaxy grouping in Ursa Major

I could not identify a satellite going through your FOV at that time. There was a StarLink near the end but it was eclipsed. As others mentioned, it maybe was an aircraft. This is from a database of over 5,000 but there are lots of classified satellites not in the database.

Are these 5 uncatalogued?
They are all galaxies, catalogued from PGC35572 to PGC35576. Magnitude 15.9 to 17.4 for the smallest one. Nearby above the chain is another fainter one that is not in my SkyX catalog. The one off the end of the chain may also be a galaxy, but isn't in my chart either.

If you zoom the posted image, there are two "spiral" trails, one much fainter than the other, side by side. The faint trail extends farther toward the bottom of the frame than the bright one -- in fact, off the frame -- which I suspect makes it unlikely that one trail is an optical or processing artifact of the other. 

If the object(s) is(are) actually "spiraling", the rate of rotation is awfully fast -- remember, the lateral motion is at orbital speed, likely at an angular rate on the order of a degree per second as seen from the ground. Might alternatively be something rapidly flashing, reflecting off something ring-shaped.

How far off the zenith was the line of sight for the images? Knowing that, and remembering that an arc second is about one meter at 200 Km, and assuming that it is high enough to be in orbit, would give a lower bound on the size of the thing.

Could it be closer than in orbit?

I think the big mystery is, that there appear to be two of them..

Wanted to see how faint I could go here at my light polluted industrial park. Local amateurs pointed out a tiny grouping of faint galaxies that they haven't been able to get much info on them or any detailed images. I tried with my 130EDF, 10" F8 Mak-Cass and finally with my 17" F8 Astrograph. Main limitation is the amount of background sky brightness here due to severe light pollution, but I'm always up to a challenge. The galaxies showed up in a wide field image in my 130GTX as a tiny little group, showed some small amount of detail in the 10", but it took the 17" to finally reveal some better detail. 
Star resolution last night was 1.5 arc sec FWHM and guiding was under 0.2 arc sec FWHM for the 20 minute exposures. Had some horrific satellite trails that had to be removed, otherwise everything went fairly smoothly.

I had one satellite trail that resembled a corkscrew, never have I seen anything like that. See below.

If you can tell me the time (start and end) of the the corkscrew satellite sub, I may be able to identify it.
