A little fact about ARP 104, is that it’s also known as Keenan’s System, after Philip C. Keenan who first wrote a paper about the bridge in the 1935 😊.

Gave this a quick look last night, wow talk about needle in a haystack! 😄

Thanks Martin On the next clear night, looking like next week now, I want to revisit the area and get a few more long subs to stack. I’ve been wondering what magnitude some of the objects are in this field?

Aah so you bought it 😄 I wondered where it’d gone, that 127 is still there 😏🤔🤔

I’m sure most of us have seen a picture of the amazing Hubble Deep Field and with the area of it being just above the Plough, it’s relatively “easy” to have a go at capturing the brighter parts of it. I had a quick go last night, using SGP to plate solve using the co-ordinates for the HDF that I found online. So attached is an image giving the area of the field, and my effort which I reversed into a negative for easier viewing. 1 single 5 minute sub with the SW 150P and AA 183M. Many stacked subs would bring out even more.

Heart & Soul Nebula, and the Double Cluster. Canon Nifty Fifty, Altair 183M + Baader 7nm filter. Roughly 5mins of 15s subs live stacked and dark subtraction in SharpCap.

Quick experiment last night with the Canon Nifty Fifty lens attached to the Altair 183m Hypercam + Baader 7nm filter. Roughly 5mins worth of 15s subs live stacked in SharpCap.

Using the finder got confusing because obviously everything is upside down and low power as it is, there was just too many stars to get on target.

Had a clearish spell between 1-2am but still couldn’t find it 🙈 Was tired, and my star hopping skills aren’t the best. Clear forecast tonight, so might try again when the imaging set up is fully out.

About an hour ago MO said it was clear for 1am....now it’s changed to cloudy with rain 😩

Very nice with the colour boosted a bit 👍🏻 Gin huh? Which one are you drinking? 😁

And IC 132 & IC 133 😊 You also captured the mag15 globular cluster C39 👍🏻

Just found them on Wiki.... The biggest, brightest one in the top pic I think is Ngc588, discovered in 1861.

Really good! Even still as a WIP 😊 Ive just started collecting data for m33, it really does require long subs doesn’t it? Surface brightness is that low. It sure looks like O3, will have to check if it’s there on my CduC 🤔

Very nice! Did you have to use a flattener when using the dslr with your WO 66? I’ve got a SW Equinox 66, wondering how well it would work with my 450D 🤔

Yeah it’s not bad, mines the first version, they do another one with 4gb memory buffer. I never use it as full size capture, the subs end up at 40mb each. As I said, the Cocoon above is with 15s subs, only 28 of them....so that’s only 7.5mins collectively 😄 If you collected 6+ hrs of longer subs....you’d be onto a winner. I hop about from one DSO to another, so not really hit it’s full potential at all. Must get into better habits 😁

I have an Altair 183, just a fan with no set cooling, admittedly yes the star burst is/was there. Found it very frustrating at first but correct darks get rid of it totally....100% Heres a recent capture from the past couple of nights, I know it needs more data to smooth it out but shows what can be done with just 15s subs, mono cam, so it’s LRGB. My guiding wasn’t set up because I was cloud dodging 😄, so subs would’ve been longer.

S.Wales doesn’t look hopeful tonight, the rest of the UK looks good though. Early night for me I think.

Very true 😏 A few subs over a few nights, then using AstroArts flicker function should help spot any movement.

Would submitting a sub to Astrometry not automatically annotate Pluto, or does it not include planetary orbits?

As said, could just need the autostretch to be applied? As for Sharpcap and doing longer subs, you need to tick the LX (long exposure) box next to the gain slider. Then you’d be able to do subs of 5, 10 mins+. Or could be that your gain just needs raising, yours could be too low if others are using 200 with the same camera.

I was out for a bit last night, but cloud and mist rolled in alot earlier than forecasted. Plate solve in sgp wasn’t playing ball, which was unusual because it’s been pretty reliable up till now. Managed an hour live stack imaging in Sharpcap, trying out the new dither function, which worked well straight away.

Yup I gave up too after only managing to capture 6 subs on the Elephants Trunk. Forecast was “clear” all night and it was even mentioned on the news that it was going to be great for UK astronomers. Like you did, I used the cloud time to fiddle with things. PhD settings and nail polar alignment a bit better for me.
