Hi, I'm keen to buy a small good quality refractor primarily for astrophotography of galaxies and nebulae. I'd like to use my Pentax K1 full frame DSLR with the telescope. Reviewing YouTube & Google the; Altair Astro 72 EDF deluxe & William Optics 71GT look like they might be good models to go for. I'd welcome the community's views on both, and any other alternatives people recommend. -

M51 The Whirlpool Galaxy 21.04.18 My first proper attempt at RGB imaging with the monochrome CCD Imaged using William Optics FLT-110 and Atik 314L monochrome camera. 10 x 300 seconds R, 10 x 300 seconds G, 2 x 300 seconds B (as I had to delete the other 8 due to technical issues). 10 x 300 seconds Luminence. I will have another look at this data once I have done more reading up on combining my Luminence data with the RGB data as it was a case of having a play around this morning. However, I'm very happy with my result for now.© vicky050373

Hi Guys,not too sure if this is in the right section but here goes.. I have an old atik 16hr and using it with a William optics ZS80D...ive tried a few times with different spacing and can achieve focus with almost all the different spacing.. the further out (longer) I go the star looks huge...the shorter the star looks smaller but using a mask I can achieve focus..my question is what's the right distance from the reducer to sensor and should I be using the extension..i need it to focus a DSLR.. anyone with the same setup? The camera has the same chip as a 314 so I'm told..

As some may remember I got some William Optics binoviewers a few weeks ago. With both my two current refractors (Skywatcher Startravel 120mm f5 & new Altair Astro Starwave 102mm f11) I can't achieve focus with the binoviewers without using the 2xbarlow nosepiece that I ordered up seperately to use as before I received the nosepiece I was using my Celesstron Omni 2x Barlow to achieve focus. I've been toying with the idea of cutting down my ST120 frac to be able to use the binoviewers for wide field views when using, rather that having it 2 x magnified with the Barlow nosepiece, but don't really fancy putting a hacksaw to the tube and cutting it shorter really. So, my question is has anyone who has or previously owned the William Optics binoviewers had/got a telescope where you could achieve focus OK with the binociewers without either having to fit the 2x Barlow nosepiece (or any Barlow), or do any other mods or buy extra equipment to get the widest views possible with them? I'm looking perhaps at maybe a Skywatcher 127mm Maksutov scope perhaps as I believe they have a large amount of inward and outward focus that might be able to help with the binoviewers. I would also consider another frac perhaps, as long the total weight with any diagonal & any EP's would not exceed 5kg as I intend to use it on the Skywatcher Stardiscovery Az Goto mount that I am buying from Dobbie on Friday. Any feedback for a decent scope to do this would be welcome! -

Up for a quick sale; I am selling my mint condition William Optics binoviewers bought off FLO last summer. Comes with two 20mm WA 66 EP's, a 1.6x Barlow nosepiece, plus also a WO 2x Barlow nosepiece I bought also at the same time from Agena Astro, so you should be able to focus correctly with one of the nosepieces OK. If your lucky you may not need them at all depending on your scope. Original box in immaculate condition. Looking for £175 which includes Royal Mail special next day delivery in the U.K. Excellent views, especially for Lunar or solar viewing. Selling to get funds for a new scope, and also due to not utilising them as much as I should do. Grab a bargain as these are like new, and currently would cost nearly £300 with the additional WO 2xbarlow nosepiece. Any questions please ask. Note; due to personal reasons I won't be able to post these off until Friday this week. <**now sold**>

I just don't use this one often enough to hang onto it now. In excellent condition, has End caps and I believe I have the box too but assume not. Turns your scope into a spotter scope, works very well. It is in excellent condition optically and cosmetically. I believe I have the original box but assume not, I will dig it out if I can. As standard they are supplied with a 1.25" adaptor but I don't have this any more. I am asking for £100 ono with a non standard, single set screw adaptor. Let's say £5 towards p&p. PayPal fees paid or bank transfer. Also on ABS and elsewhere. Cheers, Stu -

Stacked and processed image of The Sun and AR2542 (formerly known as AR2529) taken this afternoon using William Optics FLT-110 refractor, 1.25" Lunt Herschel Wedge, Celestron X-Cel LX 2 x barlow and QHY5-L-II monochrome planetary camera. 800 frame AVI processed through RegiStax6 to stack and select best 25% of frames and then wavelets added. It was good to see what was left of fabulous sunspot AR2529 which I previously imaged on 17th April prior to it's journey around the farside of the sun.© vicky050373

I just had to show it off; I'd rather be outside looking through it, but too cloudy. First impressions are pretty darn good. It's a beautiful instrument, the fit and finish are superb. This is the 20th Anniversary Edition GT81 f/5.9 81mm APO refractor from William Optics. It has a two speed Crayford 2" focuser, with a 1.25" adapter. It comes with a small "shoe"-like dovetail bar, and a carry handle that also mounts a set of rings large enough to hold a 9x50 finderscope or guide scope. Just to see how it looks, I installed the 9x50 finder from my Edge 8", and will probably leave it on the frac, since I rarely use it on the SCT. The dovetail bar is barely long enough for the two large tightening screws on my AVX mount to grasp, there is no room to move the OTA forward or back on the mount to assist in balancing once all the accessories are attached. It is threaded so a longer dovetail bar can be attached. The telescope is only 17" long with the dew shield retracted, and weighs around 8 pounds. It comes with a soft case with a fitted closed-cell insert, and the William Optics logo is nicely embroidered on the cover. I also purchased the field flattener/reducer for this scope, it makes it a f/4.7 when used, and so far as I can tell, the reducer is for AP only, it comes with an adapter ring for a Canon T-mount, which can be unscrewed; the threads are then correct for a Nikon T-mount, but there is no means to place an eyepiece in the reducer. The reducer is threaded on the end that inserts into the 2" focuser barrel along the last few mm, but it has a broad sleeve with the safety recess that fits very snugly in the focuser tube. With the three thumbscrews snugged against the brass collar inside the focuser, there is absolutely no free play to be had. Very solid. I also tried a variety of my EP's and accessories, they all fit well and without any movement once tightened. I can't wait for a nice, clear night to try out this marvel. I have a side-by-side dovetail bar coming so I can mount this alongside my Edge.
