Well mine arrived earlier today and although clouds may have been included, they weren't🙂

Setup with my OMC300 which it handles very well indeed and so trawling the lowlands around Sirius at around 110x.

Very impressive build quality and smooth motions so far. My first DSC setup and this works really well. 

Very pleased😀

I think we ordered around the same time, I noticed the AZ100 with Nexus was sold just before I ordered mine (with encoders)... looks like there are at least two new owners coming along this week then 👍

yes, just before 9pm so most likely my purchase that you saw. I noticed that there was only one DSC unit in stock earlier in the day and with recent financial approval from my lovely wife I decided not to hang around any longer!

After seeing the unit Rowan had at the IAS in 2019 I knew that I'd be getting one of these mounts sometime.  Finally pulled the trigger on the AZ100 with Nexus last night😀  

This is the beast that I got to power my dual scope/camera setup with plenty of spare capacity for a future IT and maybe mount refresh

Another process of data collected using my Samyang 135mm @ f/2, from two sessions at the end Nov/early Dec 2020. Integration of 71x300s subs (~6 hours) with an ASI071MC Pro and IDAS D2 LPF in the suburbs. Mounted on a guided AZ-GTi, all controlled by AAP.

Processed using MaxImDL (calibration, alignment & stacking) and PixInsight (everything else). Image appears slightly garish on FB but the TIFF looks nice enough on my monitor😊

A friend of mine rates the Pentax 135mm f2.5 SMC that he has.

I have the Samyang, it's very good🙂

Superb image, love the colours👍

I recognise the Ha "problem", with a dual scope setup I've collected around 120 600s Ha subs on one target whilst trying to capture the RGB subs lol

yes, nice report Adam.

'out of the box' with a slightly lighter imaging load (Samyang 135mm f2, ASI071MC, AAP, 8x50 finder/ASI0224MC guider) I usually have an RMS figure somewhere in the range 0.7-1.5". For my needs with this setup or a slightly heavier 60mm f6 scope this is adequate and quite impressive!

It's makes for a very capable and mobile imaging setup

My latest Samyang 135mm f/2 process, M31 from last Nov/Dec 2020. Integration of 88x180s subs captured over two nights with an ASI071MC Pro and IDAS D2 LPF in the suburbs. Mounted on a guided AZ-GTi, all controlled by AAP.

Processed using MaxImDL (calibration, alignment & stacking), PixInsight (bulk of image processing), with final tweaks in Photoshop CS3.

I've owned two OO scopes (10" and 12"), both with great mirrors. Still have the 12" whose 13-year old hilux coated mirror is in superb condition.

A shot of M45, the Pleiades open star cluster, captured from the back garden on 16th Oct last year using my mobile rig.

135mm Samyang lens at f/2 with ASI071MC Pro camera and IDAS D2 LPF on SW AZ-GTi mount, all powered using ASIair Pro.

42x180s, so just over 2 hours total exposure.

I bought the dewshield version of the mask, together with camera rings from here

Works well👍

As I'm anticipating cloud on Monday when I saw some clear sky over in the west this evening I bobbed over towards Freckleton for a good SW horizon. Before they dipped into the murk on the horizon I managed to grab a few shots with the DSLR / zoom lens.

An 'electric conjunction'? I'll get my coat...

Possibly just a concern that with a 14.5" aperture scope, a 15 minute exposure will likely overexpose the cores of many stars/objects in the FoV.

Nice view of the final moments of SN8 showing the level of control achieved, rather graceful I think

Does anyone else think that the top bit looks remarkably like "fireball XL5"?

Me ! 😂🙃

I also had opportunity to try the new multi star option last night. Seeing was poor but thought that it performed better than it would have normally, giving more consistent guiding over the couple of hours that I was out.  Didn't think to try a with/without test though, just selected it from the off and it worked very well so very promising. 

A couple of guided shots using a focal length of around 610mm, approx 1.9"/pixel with my FS60CB+extender/Canon 40D combo back in May 2020.

PHD on the ASIair Pro usually reporting guiding error in the range 0.8-2arcsec. Guided using a 50mm finder, f=150mm with ASI224MC.

NGC6888 Crescent Nebula / Tak FS60CB @ f10 / Canon 40Dmod / AZ GTi / 16x180s

M92 / Tak FS60CB @ f10 / Canon 40Dmod / AZ GTi / 26x60s

Technically me with my first "2nd scope", a Vixen Planet 80S used to image (poorly) the annular eclipse of the Sun early on the morning of 31st May 2003 from a headland overlooking Durness in NW Scotland.  Note that the Mylar was quickly removed at sunrise as the clouds provided more than adequate filtering lol

I justify it like this...my car has done 130k miles and 10 yrs old, but it’s still fine.  For the money I’ve just spent I could have bought say a 3 year old Vauxhall Astra which would immediately be on a steep depreciation curve.  

This is the same justification that I've used a couple of times now "for a lifetime setup" 😉

I do keep my cars for many years though, current one for over 11 years.

Wait a couple of years and reuse lol👍

This doesn't look like "regular" haloing to me and I have experience from the bad batch of Baader OIIIs from 2014😉

I now have a set of Chroma 3nm and although not orientated as commonly recommended in my QSI camera (with FSQ85) they are essentially halo-free. I emailed Chroma earlier this year to check this and they confirmed that filter orientation did not matter.

Hope this helps, 

Andy

just to confirm, I have re-done the flats at 0degreeC whilst checking that there was no evidence of the problem and they seem to work ok. So it does appear to be the result of icing/fogging on the sensor. 

I have the same problem with my SX-H35 CCD (though the symptom is very different - small black spots on the images) and have found that pre-warming with an anti-dew band before cooling works, so I may try this next time.

Thanks for the suggestion Alan

Yes,  just opened but no tablets.  Looks like I'll be adopting your process,  thanks👍
