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.
I only have room in my life for one lovely refractor, so one must go. I have acquired a Takahashi, so my beloved and well cared for William Optics Zenithstar SD66 has to go. It is optically perfect with no scuffs or scrapes. Has been used as a guide scope and astrograph on my LX90. It comes in its aluminum flight case. OTA only.
Price is £280 or 325 euros, to include postage within the EU.
PM me if interested.
Hi Everyone, need a little help choosing the right flattener/reducer for the William Optics Zenithstar73.
I am after one that does both jobs so that rules out the dedicated Flat73 which is just a flattener!
So I was wondering if I could get away with the Flat6 0.8 reducer which does say it works on scopes 70 - 80mm f/6 but doesn't list the ZS73 in the models list or do I need to spend the extra and get the Flat6A11?
Can anyone shed some light on this have email 365 where I have seen the Flat6 but had no reply.
Thanks in advance.
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.
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.
