Eyepieces befitting a Takahashi!
Highburymark replied to Nicola Fletcher's topic in Discussions - Eyepieces
I’ve always thought the second best thing about Takahashi refractors was their weight (lack of), so light eyepieces are definitely to be recommended for the 76. There are so many wonderful light eyepieces available that there’s no need to go heavy. And there may be an additional benefit in the future. If you decide in a year you want to get into binoviewing, you will already have some EPs that can be doubled up, rather than buying pairs from scratch. -
Actually I haven’t used it in eq - I use it in alt az for visual and I’m learning (slowly) about solar imaging and only need alt az for that, so haven’t experienced the technical issues that affect imaging. There’s a long thread on CN about this, most of it above my head as a rookie imager…..

Wow - best calcium animation yet Apollo! -
Recommdations for budget eyepieces?
Highburymark replied to galaxy-gazer's topic in Discussions - Eyepieces
Nice telescope. It will depend on your seeing, but I’d say those magnifications are much too high if you’re only looking for one high power eyepiece. Most nights around 180-200x will be the maximum usable powers on Moon and planets. It’s also quite a fast scope so you’ll need eyepieces that play nicely at F/6.5. -
Excellent news - thanks for posting - haven’t been on Solarchat for a while so missed this. The two or three existing solar books on the market are a little out of date now, so looking forward to this.

Actually not who you might think - don’t want to divert potential buyers from the classifieds. Another option arose! -
Takahashi TSA 120 arrived
Highburymark replied to JeremyS's topic in Discussions - Scopes / Whole setups
Well, these discussions sometimes have unintended consequences. I should have a rather exciting package arriving next week from another SGL member Jeremy - which wouldn’t have happened without this thread. I owe you one. -
Agree - To me the 13.8 billion year age of the Universe, the one figure that we can grasp, is just as extraordinary as the scale. Relatively speaking, its age is tiny. And so much of what we can see around us has existed for a significant part of that brief amount of time. It feels like the whole experiment has only just begun - the Universe has only existed just long enough for intelligent life to have evolved in one place.

Takahashi TSA 120 arrived
Highburymark replied to JeremyS's topic in Discussions - Scopes / Whole setups
Agree. It’s an interesting telescope but probably a better instrument for dsos than Moon or planets. -

Wow - I missed that it is a 6”!! That’s a definite ‘no’ from Mrs Highburymark. -

Highburymark replied to JeremyS's topic in Discussions - Scopes / Whole setups
Very nice, no doubt superb, and definitely attractive for night vision, but I will only ever own one 4/5” refractor (don’t have the space for any more), and it must above all be a great lunar, planetary and solar scope - which for me means F/7 or above. -
Takahashi TSA 120 arrived
Highburymark replied to JeremyS's topic in Discussions - Scopes / Whole setups
Isn’t that just a doublet? Nice scope though. TS seems to be offering some highly competitive prices. Looks to me like they might be positioning themselves to take over from Skywatcher as the ‘go-to’ choice for affordable Chinese apos. -

Highburymark replied to JeremyS's topic in Discussions - Scopes / Whole setups
Admittedly, very little. SW Esprit 120mm is 3.6kg heavier for the basic OTA. APM sadly doesn’t do a direct competitor. Otherwise it’s larger Chinese triplets: The TS triplets are 130mm and like the Esprit, over 10kg. Not including the Vixen 115 as it’s a doublet. -
I can only speak for the RST-135 - It takes a little while to familiarise yourself with the controller, but alignment in alt az is very easy. I park the mount in a south-facing position, and it’s a 2-3 minute job aligning on a target. Most of the time so far I’ve been using it for solar. Without any other alignment objects in the sky it’s usually fairly accurate with the first go-to - then just centre, confirm, and it tracks for about 10 minutes before the solar disc begins to move out of view, then just repeat the process and it’ll track for hours. Don’t want to veer too much from the OP’s report though. Would be interesting to know how the Crux performs in alt-az. The hope is that the idiosyncrasies of these mounts have now been ironed out and they prove reliable

Highburymark replied to JeremyS's topic in Discussions - Scopes / Whole setups
Thanks Jeremy - have confirmed the basic OTA is 6.7kg. Guess with lightweight rings, vixen bar and Baader T2 diagonal I could get that total down to 8kg, still lighter than pretty much anything in its class. -
Excellent report on a mount that’s had little coverage on SGL. I’ve got the Rainbow RST-135 and so far am also very happy with it. Agree with you about not wanting to push the payload too far. I currently run mine with a 7kg scopes - might go up to 8-9kg in future but not more. Also agree that traditional mounts are the way to go if size and weight aren’t an issue. These mounts are all about compactness and incredible performance - and not having to be too precise with balance.

Nice images Paul. Six days on the trot! Wow - weather’s been miserable in London. This afternoon had a partial break in the cloud though, enjoyed the view in hydrogen alpha, but white light was even better. Near head-on AR2835 showing lovely detail and some of the granulation you’ve picked up. 4” does seem to be a perfect size for WL observing

Takahashi TSA 120 arrived
Highburymark replied to JeremyS's topic in Discussions - Scopes / Whole setups
Thanks for replying Jeremy. I would love one. I do think it’s probably the perfect refractor. The best compromise between resolving power and weight. And mounting it wouldn’t be a problem. But it would require me selling my FC-100DC and most of my furniture. So perhaps just as well there’s a long waiting list. -
Takahashi TSA 120 arrived
Highburymark replied to JeremyS's topic in Discussions - Scopes / Whole setups
Hi Jeremy, just wondering how you’re getting on with your lovely TSA120? In particular - how do views compare with 4” Taks? Is cooldown time an issue? The comparison pictures earlier in the thread are really useful to get an idea of size, but do you know if it’s 5.7kg or 6.7kg - typically advertised specs on various websites seem to flit between the two? -
Takahashi on EQ5 mount?
Highburymark replied to Luminated's topic in Getting Started Equipment Help and Advice
Picking up an old thread here for the benefit of any Takahashi owners who are looking for some high quality replacement tube rings, and don’t want the red Primaluce offerings. I can thoroughly recommend the More Blue rings (and dovetail/finder shoe) which FLO now sells. Extremely well made and user friendly. The grey metal seems to suit most Tak scopes - even my banana coloured Epsilon looks smart, which is quite some feat. -
In the market for a H-Alpha scope or filter, recommendations?
Highburymark replied to wouterdhoye's topic in Imaging - Solar
It’s a difficult decision. Quality of Coronados is variable, and there’s not much of a support network here in Europe if something goes wrong, so it’s important to buy from a trusted supplier. If I were buying a Coronado now, I’d want to test the etalons first, which normally means buying used. Lunt’s quality is higher, though still far from certain that you’d get a top performing scope, particularly single stacked. Also the new modular Lunts are very expensive. The basic LS80 with 1200 blocking filter and crayford focuser is £9,000 double stacked!! All reasons why I opted for Solarscope filters when I upgraded - double stacked SF70 filters are cheaper here in the UK than the DS Lunt 80, though they are considerably pricier in export markets. A Quark would be fantastic for your large refractor, but only the best examples show the detail and uniformity needed for imaging. Having said all this, and apologies for making your decision even more difficult, but I know someone in the States who recently bought one of the last Coronado SMII 90 DS scopes, and loves it. They are hefty beasts, but get a good one and you’ll have a scope for life. -
Very nice indeed! Good luck tracking down the 5mm and 6mm. Will make a superb collection. Presume these are the spiritual successors to modern Fujiyama orthos, made by Kokusai Kohki? Do prefer the volcano tops at shorter focal lengths. Have a 6mm Fujiyama but the eye relief is too tight for me, so it’s in the ‘to be sold’ box at the moment.

Televue Delite adjustable sliding eyeguard
Highburymark replied to Surfer Chris's topic in Discussions - Eyepieces
I don’t have any problems with the Delite design either. If the lower caps are a little tight, they are easy enough to remove by holding the barrel with two fingers and pulling off the cap with the other hand.
