Hi all , Brian here from Darwin Austraila , glad to be here .
This is a thread to lighten up the feelings going on here about Istar , the good the bad and the ugly .

The good , I built my Istar 127mm achro from an awesome lense sourced from Istar , very nice lense at a great price .

The bad , I built it during last years wet season so I could not test it for a few months ,, Grrrr that's tough ! .

The ugly , nothing at all , but I got ya guys though didn't I ?

I have had a few great sessions with good friends and their refractors 100mm -150mm synta achros a C8 and an 127mm f7.5 Triplet.
All were like waiting wolves for me to finish the build , and the weather to clear , now both are done we have had a few sessions , cold beer's and great fun testing these scopes against one another .
I wont go into the ins and outs on this as I have seen here that kind of discussions causes distain amongst certian ( un-named) people here .

This thread is to hopefully go above all that jazz and talk about the good times we all have had when out under the night sky , good scopes and great company .
Leave your snobbery at home , please?.

And my Istar is certainly different , draw you own conclusions and please contribute in a positive way .
Enjoy the few photos and I hope there will be many more posted by fellow refractor lovers , and thank you very much .

Brian.

Istar do make a nice looking scope but I think your white one with silver highlight is right up there Brian. The 150mm f/10 I had for a bit had nice optics but was a little longer and heavier than I wanted to handle. Once they prove their version of the chromacorr a shorter scope combined with the correction might be attractive.

Hi Brian,
so you build your own refractor with the Istar lenses? It looks indeed very nice. Do you have a build report or some pictures of your building steps?

Hi Brian....

I always envy you having a nice home , whereby you can enjoy with your Istar , whenever weather permits....

Whereas I am staying in a high-rise building , with a very limited West viewing, as such need to dismantle my equipment, bring it outside to an open area, setup and dismantle again after the viewing session..., then bring it back home, and mount it back.....

And I also cannot be like you , by purchasing the lens cell...from Istar.....and build the whole OTA....

Hope to see more report from you soon .....

Regards

James Ling

:cool: Thanks Roland , if you are interested just google 'Istar scope club' , you don't have to be a member to read the threads , just go to 'Istar ATM' then open 'Istar 127mm f8 retro fit' that me and there are 3 pages of my build there for all to see with photos , remarks and all that .
Enjoy .
Go for it you wont be disappointed .

Here is the moon at 3rd quarter shot taken at prime focus , 1000mm using my Sony Alpha 200 DSLR , zero work except the sizeing to fit it here .
The views thru my 14mm TV Radian mimic this well , every one that's looked thru my 127mm comment on the contrast and lack of CA , and the inky black space around the moon .

Here is probably the 'Acid' test for any refractor lense ever made , a rooftop taken in full sun with the above gear , raw shot again .
you will be hard pressed to se any CA in this photo , this was the first shot I ever took with this combo , the roof top is 500 metres up the street .

When viewing thru this lovely Istar achromat the views are the same .

Hi Brian....

looks like your ISTAR achro is performing better than my WO88ED , in terms of the colour correction....

And so happen I am enjoying my WO88ED with my friends last night at the 1st quarter moon, I can still recall mine still have a slight CA, and I even took a photo shot but is badly taken....so better not show it here....

Regards

All you need now Brian is to remove the Saxon script from the OTA and get an Istar sticker on it instead.

I am still waiting for Dan Crawford to finish my focuser for my 80mm f15 refractor (the brass cell one), then I can start on the Carton 80mmF15.
The Takahashi has been gathering dust due to clouds, wedding and housemoving getting in the way.

After I finish the two 80mmf15 scopes I will start on the 4"F12-F15 Steampunk to go onto my Gaunt Eq mount. You can never have too many refractors. (Having said that, I also have started drawing up for a 12.5" F6 Dob-Newt.)

Hi Brian....

How is your last weekend for your photo shoot????

Over here in my army club house, i am enjoying it with groups of people that I never met them before.....

And it seems that I am enjoying spending an hour to set up my 8" ISTAR , just for 3 hrs of the event, then spending another hour to dismantle and load back into my car.....
All these didn't consider time at my home side for the loading and unloading for before and after the event...

As for me, I think enjoying this hobby is more important, by bringing the fun to all people who are interested, and showing them something they have not seen in their life.

This photo shows me setting my 8" ISTAR up for the 11 days old moon, while group of people gathers around me, waiting for the session to begin....

Regards

James Ling

Cool photo James , I love your scope mate .

I forgot to mention this , I live 100 metres from 2 shopping complexes in the centre of a city of 40,000 so the light pollution here is horrendous at home , this is where this shot was taken from , my front deck .
Awsome contrast , this scope .

I had a family around the other night for a look at the moon and Saturn before it goes and I will post a few more photos when I down load them .
