This is part of an image I took of the Bee Hive cluster on the 4th  Nov 2022.

When I looked up objects in the frame, when I got to PGC2819573 I got this redshift 1.6940 on simbad

I wrote a wee python script to chug through objects, and I get this redshift 0.7578 for it

It is reported as a quasar, what I would like to know is it possible to record something so far away with an 8" scope, or is it something else or a clitch in imaging

.

Not asking about coma ect, that is obvious.

I have this hair like feature in two images, imaged months apart, I find it strange it would be in two separate image sequences, but only the two, of complied images of the moon I have done seem to show it.

If one evening, maybe, other images I have are lit as the moon is waning. So if it is a cliff, they wouldn't show it

Sort of failed again, odd APT can't record image. I know cable length.

Well it is working with, one 3m USB 3 and one 4m USB 3, to the short USB 3 cable to hub. It remains to be seen if there are any issues, what I am really struggling to understand with is 1 m i.e. a 5m and a 3m caused issues. Yet, the 3m and 4m seem to work.

Bit messy but a screen grab of the remote desktop.

So what I have a short USB2 directly behind the comp to outside and a weatherproof box, then a 4m USB 3 to the short USB hub cable. Ideally I am looking at a short USB 3 to the external socket and either as is or change the cable to the hub 4.5m USB D cable, but fitting that to the is more fiddly than to the extension.

This isn't as neat as I would have liked, but it works, it just means the power for the system, hub, mount, Canon and USB dew heaters, comes from one part of the shed, and the USB from another part.

Thanks for all the input,

The two are then linked by a cat5e cable.

 

Do you have any idea of data speeds.

@m40 & @david_taurus83, cheaper option, just move the weather prove box, to the front of the shed and run the USB from there, it's basically how I ran it before but through the window, everything worked well, the eqmod usb, the canon camera, the ASI120mc and focuser, the only thing on it that is USB 3 is obviously the ASI 120 MC, and depending on settings and resolution, I can achieve up to 65-70fps.

@m40, the only laptop I have in the system is the one I keep an eye on stuff in bed, via Ethernet. The computer in the shed is a desktop, remotely controlled from either my bedroom computer or the cr**** laptop, which, whilst more modern than the shed computer, wouldn't be up to the task, however running a copy of Linux it's OK to keep an eye on things.

If memory serves me right, Cat5 is 100Mbs which is very slow, even USB 2 is quicker, if I run a USB 2 from the end of the 5m USB 3, it seemed to work, but it was late, and I was tired, so not everything might have. I do know if I ran the USB 3 from the comp to the USB 3 12v powered hub, it worked as it always has, bar other glitches.

Thanks for the input.

Thank you so much for the help! Is this the only thing I need?

Well I started with a 200P same focuser, you have the PDS, more photographically inclined, shorter tube so easier for cameras to focus. You should i think have a M42 mount on the focuser, metal ring around the outer part of the focuser, or maybe a 2" adapter with a male thread, if the later most likely, this needs to fit the eos m42 thread, change the 2" m42 to an m48 and eos m48 and you get a wider view with less vignetting

Hi, sorry for asking what I'm sure is a pretty obvious question but I'm completely knew to this hobby. How would I go about connecting my 130pds to a canon dslr? Thanks to anyone that helps.

Basically you need either an M42 or M48 (preferred if full frame Cannon) to Canon EOS, M48 I believe is the 2" mount screw thread on the scope, but would need to check this

P.S. and Edit dont ever be afraid of asking stuff

Have a search for a startech USB extender you can get either 5 or 10M USB extenders. They are not cheap but I used the 5M usb2 version for some while with no challenges. Another thing to look for is USB over cat5. You can get very long lengths, I have been using one over about 15M with no challenges. All the best.

Meant to add, you need to be aware of when using hub extenders is that power the extender off last or the USB port in your device may fail because of the load.

If I use USB 2 in place of the USB things worked (and these were patched together cables) , well it was only one test period.

So how do you do your CAT5 ect.

USB 3 is notoriously picky and tricky -- plenty of folks have trouble with much shorter-cabled setups. For example a lot of CEM70G users struggled early on before the community figured out that short, high-quality cables were the only way to reliably connect to that mount.

Sounds like a perfect application for a single-board computer at the scope, together with WiFi or Ethernet for remoting in to it. Basically what I do with my Pi when I want to park my [removed word] in my nice cozy recliner. For me it's a Pi 4 running StellarMate OS, but lots of folk use Intel NUC or similar Windows critters. Nice thing about INDI is you can either run the client app (KStars/Ekos) on the mini and remote in to its desktop with just about any device, or run just the INDI server and device drivers "headlessly" on the mini and run your client on your inside computer, connecting the two over the net. 

I do most of that, remotely from my bed, I run an Ethernet cable (cables are usually more reliably than wifi I find) to the shed it works perfectly on Linux or windows remotely.

Where my shed is my phone does not really get Wi-Fi well, and the repeater is patchy, hence wires. I don't have an issue running a shorter cable that will work, I just asked if a powered hub at the end of 5m cable would work.

Connecting stuff over the net isn't an option unless there is an easy way, ie close to a router

I use APT and plate solving, and it can take 3 or 4 attempts as currently setup, but I am experiencing other issues, re cable, but usually it requires at least 2, not sure if resolution and accuracy is an issue, ie 1000 pix 100pix 10pix

I find APT stops if 5-10pix or less

If polar alignment is rough 1000pix would be quite good. I can get a lot of pixels out and still find the object, mmph like I said other issuse

I thought I would post this here.

Seems my plan of routing the USB to outside easy access is scuppered by the USB 3 cable length of 3 m to the access point, plus the 3 m cable to the powered hub on scope fails the demands of USB 3 length, before I drill another hole in my shed, and running the cables to other than my chosen point, would it be possible to run the first USB to a powered hub, then the next cable to the scopes powered hub, total length, pretty sure first cable is 5m, length of shed 10ft, up to bench is maybe 2ft, plus 5" and 8" leading outside, I have 2 other usb 3 cables 3m and 4m.

These question being, can I run a USB to a powered hub 5m away, then run a USB from that powered hub to the powered hub on the scope, and it works as though I just ran a USB 3 direct from comp to scopes hub.

Yea I know dumb question.

A superb animation Nicola and the single image just before occultion is excellent too.

Thanks, I could have used any of the images for the single one, but thought just that little gap works.

I am a little disappointed with the quality of the moon, but it wasn't the best in terms of cloud, but I was fortunate to actually get to see and record the event.

I think this was the first time i've seen a lunar occultation of a major planet and i can recall very close conjunctions of Venus, Jupiter and Saturn before, but never an actual occultation, so its one off the bucket list 🙂

 

There was one visible between the crescent moon and Venus Dec 1st 2008 UT 15:40 ish on (Upton) I didn't have a scope at the time but a rather longish lens on a bridge camera, cloudy then too.

Of all the regular, rare but repeatable events . i.e. Venus transits (saw one of those or rather projection of it) Jupiter Saturn, Venus-Pleiades (2012 and 2020 both cloudy), most are cloudy where I am, even the great Leonid shower back in 1999 it was clear in Inverness, but cloudy on Skye. (roll on 2032, bet it will be cloudy).

i saw Mars going behing the moon using 10x50 binoculars.  I only went out in to the back garden beause I woke up very early. This was unplanned as I had to go to work afterwards. It was very interesting to see. I am really glad I saw it, as I  have never seen this before  and don't know if I will see it agsin!

Hopefully over the weekend I will get a proper look at Mars with my 6 inch Mak, I have not had a good view of it as yet this year.

Some years back 1/12/2008 there was an early evening one between crescent moon and Venus, clouds got in the way of that one.

Now I have woken up a little, and we all know a full moon isn't great to image and certainly not from a single image with cloud passing by, but I did a little work and

Great animation. Mars wasn't occulted in my location in the southern United States, I'm glad you were able to capture this!

Thanks.

Unfortunately, when it reappeared, it and the moon were below the roofline of my shed.

I did this with my SW200P and Canon 40D 25 frames 10's apart, so just over 4 mins, quite a bit of cloud, by the time Mars reappeared the moon was below the Shed roof, and guess what it was clear.

I did this with my SW200P and Canon 40D 25 frames 10's apart, so just over 4 mins, quite a bit of cloud.

My effort, re-emergence was blocked by the shed roof

It is 25 frames 10's apart

Got this of Mars and the moon, 25 frames 10's apart, a lot of cloud, sod had his hand at play because when Mars re-appeared the moon had dropped below the shed and clouds had p'd off

I got this between the clouds 25 images 10's apart

Unfortunately the clouds clears, but the moon dropped below the shed's roofline before Mars reappeared, I had got the planetary camera set up for that.

I used the kit Barlow on this on my 200P, with a Canon 6D, so I guess a 3x might be better suited for the 130PDS, as to quality I will leave that to others.
