They arrived today !!! Only placed order mid afternoon yesterday. They’ve tidied up my rig by removing about 4m of wrapped cables 😊

Thanks for this. I’ve ordered a couple with nice short leads 👍👍 Andy

Thank you, Are they any good ? because it’s exactly what I want, short cable on the strap just to reach power without wrapping around the scopes etc. Andy

Anybody know of Dew Straps that have short cable lengths ? For scenarios where straps are connected to a power box mounted on scope. Andy

Thanks both, that was what I thought but got in a muddle 😂 thanks again Andy

Hi All I seem to be confusing myself lately & I should know this… are calibration frames telescope specific ? thank you

Southampton very clear tonight….

I don’t normally like to self congratulate but Thursday night it seemed everything came together, I’ve struggled for 18months or so trying to get a “good” result, and was beginning to think the move from small refractor to RC8” I had bitten off more than I could chew, tweaking collimation, different guiding methods, filters, focusing issues, NINA & APT issues, I got a shot I actually like, I know it’s not the best but it’s the best from me so far, so I’m chuffed to nuts. M1 Crab Nebula 😬

Is there a middle ground that you’re aware of ? There’s just so many out there and only want to buy once. I was thinking the ZWO or Optolong ?

Hi All, Question on UV/IR cut filters, I understand why filters are sometimes very expensive, however, where I get confused is when the same type of filter from different brands price varies so wildly ? can anyone shed some light on why a Baader uv/IR costs say £110 and an svbony £12 ? And every budget in between, They all purport to do the same job, are Baader pulling my pants down or are svbony making me throw money down the toilet ? Any real world experience of high end vs budget filters ? regards Andy

Well I’ve been trying some flat captures today and that pattern is WEIRD !!! It’s not the cloth (removed), it’s not the filter (removed), it’s not the reducer (removed). I’ve cleaned the glass in front of the camera sensor with a cleaning kit and pattern is still there , however, and this is where it gets really weird, it’s not always there ? I did a batch absolutely clear of pattern then another batch and pattern returned. I’m at a loss now what it might be.

I don’t suppose one of the experts in the dark art of 3d printing on SGL has made an adapter to secure a right angle viewfinder to the polar scope on iOptron Skyguider Pro ? Regards Andy

Maybe ‘pattern’ is a poor choice of word, the fabric is muslin, it has a weave that is like a grid, I put three layers crossing to avoid the ‘weave” affecting the light, see the diffuse panel below

No change in focus, the 9.4 & 10 is the temperature -9.4 -10, just how I configured the naming convention so I could easily tell which set of dark frames I need to use. I actually used an A3 light pad but I think the issue could be the weave pattern of the white cloth betweeen scope and light panel. I will try without cloth.

I used NINA, only exposure, binning & dither were used. for the flats I let Nina work it out with a flat light panel and cloth over scope.

Does the diagram suggest I should set temp to say -13oC ?

I do have another 100 or so subs from night 2, but I ran out of Dropbox space 🤪

Dark current, not sure what this is ? I will Google. I did think the images were very noisy considering it’s cooled (-10) maybe I need to rethink my settings and build better calibration library.

Thanks for this, it would seem I’m on the right track. It’s GEM45 mount, still getting to grips with the balance and guiding. flats were my concern but didn’t want to lead you. Used an illuminated art panel and just let Nina sort it for me, I’ve noticed that one side cast to most images. collimation is much better than it was not perfect though. dithered every 4, changed to 5 for tonight, binned 2x2 also. yes, filter, I can’t decide ? I’m in bortle 5 not sure if I need, maybe I should get just get a IR UV ? I just didn’t want spend hours capturing if it’s unworkable and I think you’ve proven it can work but needs a bit of refinement. 👍👍👍
