SvBony SV105 software control question
heathenwoods replied to Astro_Dad's topic in Getting Started With Imaging
I've got an SV105 and use it (occasionally - keep meaning to upgrade!) with SharpCap 4.0.9268.0 in Windows. Exposure, gain, contrast are all available and work okay. The camera is pretty limited but I've no problem in SharpCap so it might be in the Windows<>Mac conversion? -
M27, think I've over processed it
heathenwoods replied to heathenwoods's topic in Getting Started With Imaging
Thanks, Laurence! I haven't really looked at GHT and have continued to use the Asinh tool; I'll have a look at it tonight! I'll also have a look at Hasta La Vista. Cheers 🙂 -
M27, think I've over processed it
heathenwoods replied to heathenwoods's topic in Getting Started With Imaging
I've come to realise just how powerful levels and curves are! I think I've got all the curves more or less in the same place now and it's been fun trying to push just a little bit more detail out of the core. It's been amazing to see what a huge difference three astute tips made 🙂 (Although I'm not sure the background isn't a tiny bit too red now!) Carole - not quite my first but my first for quite a while. Although I realise the CG5 is bordering on 'vintage' it looks as if guiding should be relatively straightforward to setup (🤞) -

Okay, I've tried to follow @ollypenrice's advice (as much as my data allows!) and I think this coming on a little... -
M27, think I've over processed it
heathenwoods replied to heathenwoods's topic in Getting Started With Imaging
Thanks very much, Olly. That is all very helpful. Starting from your last comment, I'm not dithering - I'm just using the camera with an intervalometer. I'm guessing that I could set up the mount to dither with Phd2 or similar software? I don't have a guiding setup but this might be a god way of familiarising myself with the software before fully going down that route. The blue/green balance is probably out because I tried to push the blue in the middle of the nebula with curves - possibly the source of a number of issues! And, yes, I meant flats when I wrote lights for the second time. I'll try reprocessing using those tips - again, thanks so much for taking the time to make these suggestions. -

On reflection, this image owes a lot to the classifieds here and Astro Buy & Sell: 90x60s lights with a Canon 1000D through a 130PDS on a grumpy old Celestron CG5. Also: An Altair Astro CCD-CLS filter but I'm not yet convinced it's a massive help. Bortle 5 skies 30 flats (I've assumed I leave the filter on for these?) [edit: had originally called them lights] 30 biases Stacked in DSS and played with in Siril and PS. I think I've overdone it as the background looks quite uneven and gritty. I'm coming to the conclusion that (i) I need to keep track of my processing workflow and (ii) I need to look into getting guiding worked out.

Replacement eyepiece caps
heathenwoods replied to heathenwoods's topic in Getting Started Equipment Help and Advice
..and now you point me towards it, so obvious! Thanks very much - I think I must have just skimmed past 'Cleaning and...' without clocking the 'Protection' bit. [Edit: That was replying to @GSmith. Thanks also to @Zermelo - I was struggling to find the size I wanted, 50.8mm/2" among those links] -

I've found a few old threads with links to UK-based sellers of eyepiece caps or ebay sellers but the stores are either gone or no longer sell to the UK. Has anyone found anywhere recently? I'm looking for 2" mainly. Cheers.

That is beautiful and a standard to aim for. I had my second attempt with the 130p-ds. My daughter said that Orion was her favourite nebula - none of my ids have shown any interest in astronomy up to now - and so I had to try and get an image while I could; it's begun to disappear behind the trees at the bottom of the garden earlier and earlier in the evening. Looking at the forecast Sunday evening might have been the last chance I get in full darkness. I know I blew out the core but that is something I can work on in the Autumn. I'm pretty chuffed with it as it's been a few years since I last had a scope that I could think about doing this with. Stars at the edge are showing the effect of trying to stack a 60x30s image with a 60x60s image. Photoshop didn't align them perfectly at the edges.

I had a very similar story to Rob above. This was my first bash at imaging with the 130P-DS and with a new-to-me CG5 mount (thanks to everyone across the two threads I posted recently for help with both focuser and mount!) I wish I'd spent longer and there was some light cloud drifting across throughout the session but I got an image out of it so no complaints 🙂 M45 75x45s 20 darks 20 bias 20 (wrong) flats - made w/camera lens a couple of weeks ago. I was lazy - I wanted to use the SiriL automated script 450d Stacked and a bit of processing in SiriL and a few curves in Photoshop

Wow. Thanks for the advice and kind offers. What a helpful crowd, thank you. And no insult taken, Carbon Brush, I know I would risk wrecking things if I tried myself! I'm about to set off down the road to Potts in Derby (mentioned for locals to nod their heads at - lovely, old-fashioned shop) who should be able to sort me out. Otherwise I'll be in touch with one of you kind people. Thanks again.

Hi, So, I bought myself a new mount second hand - Celestron Advanced GT/CG5 - with the understanding the power sometimes needed switching on/off a couple of times. I was fine with that as I've just sold an old nexstar frac that did the same. However, I set it up tonight and when I swapped the power supply for another one it seemed to work fine. And then it didn't. One of the pins inside the jack has snapped off. Obviously, it was a problem waiting to happen. But now it doesn't work. Not the seller's fault as it happened when the mount was with me. I'm a bit annoyed especially as my dad had given me some cash towards it as a birthday gift (I'm not young, he's just a kindly old fella). And I've not even got anyone to be angry at. But I'd like to fix it if possible. Unfortunately, the mount is old and the part that needs replacing (NXW414) is discontinued and isn't available anywhere. So, my last hope is a physical fix. Can the power jack (in the photo) be replaced by this ebay part? (Also this on Amazon but I don't really need 30) Would it be an solder? I haven't a clue but my kids have got a soldering kit... (Oh. ANd what's that small blue square under the jack?) Or any other ideas?
