Hi everyone, I've just received my new cem70 mount and now looking at cable management so need some shorter cables. In particular I need a 5.5 x2.1mm centre positive  to usb c. This will connect the mounts hub to power a mini pc (USB c input). Anyone know where to get these, I can only find pd charging cables. Who would of thought the topic of cables would cause problems.

Hi Frank and welcome to the lounge

Looking really good Nigella, really looking forward to hearing more of how you get on with this mount, in particular cable management and guiding performance. I may well end up with one of these too!

Look forward to hearing how it performs Nigella

Wow that really does look so much better thank you Bugdozer!!! I really need to learn whatever you did!! My main issue is my glasses have a grey tint (early manacular degeneration) to filter out certain light wavelengths and so my perception of colours is skewed and without glasses  my near vision is rubbish lol. Once again many thanks, oh and our nieces son is a radiographer in Sussex too!!!

A warm welcome to the lounge, we got relatives  living in Ashington!

Ooer yes please

Thanks Bugdozer, is there an easy way of doing it without darkening the whole image, is it done in levels and curves for example in gimp??

Had a nice sky at home last week so managed to get out and have another go at the Eastern Veil but this time with the 2600mc pro, 29 x3min exposures plus darks and bias frames, stacked in APP and bit of basic processing in Gimp. My eyes are not what they were and having to wear specially tinted glasses does mean I struggle with processing so what I think looks ok'ish may look awful to the rest of you lol. Anyhow as always constructive criticism is always welcome. 

Maybe the seeing was not great, warm air currents and turbulance in the atmosphere can play havoc. Of course I'm just guessing and I'm sure some more knowledgeable folks will be along soon with great advice.

Fridays nights quick session consisted of 2 targets in Cygnus. First up was a favourite of mine when using a DSLR, so thought it time to see how the 2600mc pro compares. Well I have to say I'm astounded at the difference especially given the difference in acquisition time, this target used to take at least an hour and probably longer with the dslr to get the same result!!! Anyhow here it is, The Veil Nebula, only 10x 3min  lights plus darks and bias frames, L-Enhance filter.

Had a very small window of opportunity the other night so thought Id give M13 a quick go, what really amazed me was the number of other fuzzy little galaxies in the image after processing, I'm really starting to love the 2600mc pro camera!!!. of course as per the norm I will add more date in time, and hope against all odds my processing skills will improve. one thing I have also noticed is the output from one piece of software into another eg say APP to Gimp can be strange, the image seemed very light in APP and yet quite dark when loaded into Gimp and exported as jpeg, anyone shed any light on this please? 

35*1min plus darks and bias, camera set to 100 gain 20 offset cooled to -5.

I don't mean to dishearten you but the first thing i noticed was the stars seem slightly egg shaped, are you using a field flattener? Has the telescopes collimation been checked? how do you focus? what mount are you using? Maybe it was windy, a SW200p is a large telescope and even a breeze can affect results. I would definitely try again without the filter and see what difference it makes also from reading around the web there is lots of info on how to get rid of the green tinge.  More data capture is always a good thing. Maybe shoot some bias frames and add them into the stacking.

Get the very good book Turn Left At Orion, it is invaluable.

Thnx for the advice Olly, I'll have another go at it, I have to wear specially tinted glasses which can play havoc with my colour perspective, mind you that's better than not wearing them as I'd see naff all lol

Thnx guys, ouroboros I discarded about 20 subs due to satellites!!! I also could of framed it better I think.

Finally got out with the new camera and managed a quick session. This is only 50x2min subs plus darks, camera set to 100 gain, 20 offset, temperature -5. I need much more data but after all the clouds we've had impatience got the better of me so processed what I have so far using APP and photoshop. I know its far from perfect so tips very very welcome, this is a huge step up for me moving from dslrs to a dedicated OSC also my processing skills leave a lot to be desired!!!!

Why not go for a dedicated OSC camera, I used canon dslr 1000d to start then moved to a Canon 6d both astro modded, finally I've bit the bullet and acquired a 2600mc pro, which is a fantastic camera.  Srry I'm presuming your hooking it up to a telescope.

Last night was lovely and I managed to get my imaging kit up and running, however as I sat there I thought wouldn't it be nice to have a chat (via keyboard to keep noise down) with like minded folks, so I was wondering if anyone has set up a discord channel or similar?

I thought with dslr it was better to use bias frames. Maybe give them a try.

Lovely clear sky here so far tonight, I got an imaging run going for M81, however plenty of satellites whizzing through my frames doh!

Dan siril will convert the files but then may as well use siril to do the stacking etc too. I have siril but find it complicated too!!

As far as I can see dss is set to debater, could it be I saved the files as tiff instead of fits

For some reason they are greyscale 16bit?? Could I of saved them incorrectly when acquiring them in NINA??

Just loaded subs back into dss.
