And here is the photographic evidence of my totally uncontrollable ordering finger on my keyboard. I’m not sure when I will get the chance to open the box to be honest but hopefully it’s soon.

today a few bits arrived. Flash adaptor and bits for the Sony SLT-A77ii I'm awaiting and a mini telescope masquerading as a finder

TAL 8x50 finder from a TAL2 and wow that is solid and huge! Feels like the focuser could do with an overhaul as it sticks a bit, some internal dust but very sharp and clear. Single circle reticule for targets. Will have to see if I can sort end caps for it to protect those nice lens coatings. Looks like I'll have to drill whichever OTA I want to mount it onto as it has a 2-part shoe, so will be a while before I get around to doing that I expect.

A couple of books, courtesy of @Second Time Around, as soon as I received them I lost 20 minutes of my life getting absorbed in the surprisingly fascinating theory behind optimizing mirror supports to allow various “sags” to cancel each other out!

Those look very interesting Magnus!

One of these care of @billhinge

So that I can put my T-Rex alt-azimuth mount on my Berlebach Uni 28 tripod:

If needed this will go tall - the dovetail clamp is at around 2 metres at max:

Most of the time though the legs will be less than 50% extended.

How much weight does it save you over the steel tripod you have?

The overall weight is about the same. I just wanted to use the Uni 28 with the T-Rex Mount :smiley:

At some point I will compare the EQ6 steel tripod + pillar extension with the Uni 28 and see how they compare in terms of performance and convenience with this mount.

I suspect there will not be much in it but I do like wooden tripods :smiley:

For my initial foray into EEVA, got this on sale from @FLO to use with the ASIAir Pro.... a ZWO ASI 294MC (non cooled, as I'm only doing shortish exposures). By all accounts this should be more than enough to get started🤞

After much deliberation back and forth, and good advice from everyone on here, I decided that I would get a 2x telecentric focal extender (to complement my 2.25x Hyperion barlow). These ES Focal Extenders have a good reputation and this 2inch variant will also allow me to try it with the Pentax XW30 too 🤔 This thing is quite heavy but fortunately, I now have the adjustable counterweights for the dob, to keep everything in balance 🤞

Well I had an 90mins with the 10" dob before the haze came over and can confirm that this ES Focal Extender is effectively optically transparent and worked perfectly with all the Pentax XWs (30, 10 & 7) as well as the Panoptic 24 & 15mm. The moon using 2x on XW10 & XW7 was incredible... lovely bit of kit 👍

I've now ordered the ES 2x Focal Extender 1.25" variant, as it's significantly lighter and should work well on the StellaMira and remain balanced in the Zero mount 🤞

I've used both the ES 2x Focal Extenders and they are really good :thumbright:

I'm still waiting for that Thornbury haze to come down here - hope it stays away for a bit longer !

I’ll be interested to hear your result John.

My own part in this same transaction is that I symmetrically bought the wooden Uni tripod from @billhinge of which John’s EQ6 head was a spare, to directly replace my SW steel tripod. So I too will do a like-for-like comparison. Personally, I think the steel tripods are quite springy, but we’ll see...

The steel tripod that came with the T-Rex mount is a 2 inch steel legged EQ6 one. Pretty sturdy I've found. I prefer the look of the Berlebach but we will see. The BB did well tonight with my 130mm F/9.2 triplet frac on board. Didn't try and compare the tripods though - too busy observing Mars and the Moon under excellent seeing before the fog came along !

Same here... that “haze” turned into a full on proper fog 😬Still, got 90mins on the moon and Mars too and an excellent view through the new dob 👍Hope you got some good views 😃
