I think to do this on one laptop you'll need to have the ASCOM as well as the native ZWO ASI drivers installed.. in SGPro or PHD you'll then get a choice of more than two cameras to connect to (ie two as ASCOM nd two as ZWO ) Dave

Nice one Steve.. an appropriately sized filter step down ring will I believe get rid of the diffraction effects of the lens's iris (not done it just read it somewhere)

Definitely!

Indeed they do.. similar in absolute size too with lots of HII regions. But about 3 times further away

Looks similar but isn’t.. it’s a member of M81/M82 group

Cracking image and congratulations to you and Tomatobro on getting the dual rig running Dave

Just seen it.. well done Carole! Dave

That is what I wrongly assumed.. Nikon fit lens has 4 screws for a start

Excellent.. but probably worth pointing out that this looks like it will only fit the Canon version of the lens. I got a similar one from Astrojolo and it doesn't fit my Nikon version. Dave

Welcome back Goran! Very nice object which I shall add to my to do list and impressive for OSC under a 95% Moon, what did the Ha look like and did you add it in? Dave

I believe that it works on newer Macs, there's certainly a Mac file to download which I tried without success on my 2013 IMac . and seem to remember reading somewhere that there are PS and standalone versions

Hi Olly If I remember correctly I downloaded it from Sourceforge.. unzipped it then copied all to the Program files/pixinsight/bin folder.. then opened Pixinsight.. opened the Process menu.. at the bottom of which is "Modules" click on that to open "Install Modules" search the "bin" folder for Starnet and install.. I did find out how to do this from a video somewhere but it was months ago now and no longer in my (or my pcs) memory .. HTH Dave

Just watched that video, very informative.. so thanks Wim

I can vouch for that.. looks like you've just popped off to the kitchen though!

I'd have thought that so long as the piggybacked stuff doesn't cause any distortion (cant think why it would ) of your RC and mess its images up then it'll be ok. Not sure they'd work at the same time though (flex) so you'd want a separate guidescope for the refractor, plenty of images of folks with setups like this out there.

That's what it says it does on the tin... Wim.. Dave

More like Detention! Barry Wilson has a useful tutorial on "Boosting Star Colour" on his SmugMug site which is worth a look

Family and friends encouraged me to take a look at the penumbral eclipse last night, and I'm glad they did. RGB through Esprit100 and ASI1600mm and high cloud.. Had to wait for it to rise above the trees and rooftops. I've also included a diagram showing the positions of the penumbra and umbra at that time.. AS!3, Registax and Photoshop. Dave

Vlaiv, Olly I don't know for sure but isn't part of what Vlaiv is describing similar (or has the same effect as) ArcsinhStretch in Pixinsight., ie preserves colour ratio as you stretch Dave

Piggy backed will be much easier to balance than side by side with such different scopes.. The Esprit100 is pretty good too, 550mm fl, with the flattener it covers APS-H which is a bit smaller then full frame.... what camera are you thinking of using ? Olly.. do you have a source for used FSQ106Ns.. other than your linen cupboard! Dave

No, it’s just a flattener Dave

Can I suggest leaving the Moravian on the guided scope.. it'll be much easier to align... you'll be able to go deep with long subs... your stars will be lovely with those little spikes on bright stars from the KAF sensor.....you'll get a much wider field mono image as well.. and at 1" pp you'll be at or below the seeing limit anyway, binning the ASI178 2x2 will give the same resolution.. Plate solve and frame on the 178 equipped scope through a second instance of SGPro Dave

So I understand.. although the latest I read (admittedly a few months back) was that it wasn't high on their priority. As I run very different exposure lengths on the two scopes I'm not sure that for my setup it would make much difference in terms of improving capture efficiency, with more equal length exposures it clearly will.

Another excellent image to add to your amazing catalogue of planetary nebula Peter.. Dave

Yes that’s one of the dual scope problems with an OAG.. another is drift whilst the primary does autofocus.. (if of course you do it 😉) .. although this isn’t much of an issue with the Mesu.. and another I have as I’m using SGPro is the inability to sync the exposures for dither, in total I lose about 1 in 6 of the secondary scope subs.. (it runs 2 min or 5 min subs the ccd runs 10 or 20 min subs.. I dither every second exposure on the ccd.. ).. I’m also pretty sure that the relatively short exposures on the CMOS camera help mask any flex .. so maybe Tomato that’s something else to examine ie whether for Galaxy season 10 or 20 minute lum on the primary and 1 or 2 minute RGB on the slave through a cmos camera (I seem to think you have one) would work ..
