I'm looking to get a reasonably portable astrophotography set-up, using a 60-100mm refractor, with a suitable goto mount. I spotted the Explore Scientifice exos2-gt with pmc-eight goto system, which looks like quite an elegant solution, and wondered if anybody in the forum owns this mount, and what they think of it's performance & usability?
This may be an artifact, but I took this shot of the Orion Constellation from the Canary Islands and it showed a small nebula around Beteleguse. Do you think this is real? The shot was taken with a dual band filter which brings out the Ha. I initially assumed it was a camera artifact, but I took more shots with different camera positions and it was still there. There are some on-line articles about such a nebula. My first reaction was to edit it out, but I think it might be real and only visible because Beteleguse has dimmed by over 50%. What do you think?
Hi I have an opportunity to acquire for visual imaging, a 2nd hand (manufactured 2000) Russian TAL1 reflector telescope for about £60. Is this a reasonable price,?
Being new to astronomy & not currently owning a telescope I've no idea whether TAL is a quality product, so I'd welcome your thoughts.
Note: This scope is in the USA, so international shipping may prohibit a sale. However, without the heavy Scopeguard case the shipping cost will be substantially reduced.
I can provide a full frame image taken with this scope if anyone is interested.
Reduced to £3155 for the complete package. I will consider offers, but this is already close to my bottom price.
I’ve decided to sell my Takahashi Epsilon Ɛ-180. The scope and optics are in good cosmetic and optical shape. There are a few minor tool marks around the collimation screws but otherwise no issues. The primary mirror is centered with a Catseye Hotspot.
The scope will come with the Takahashi corrector, rings and top plate ($457 add-on), front cover, Scopeguard case ($500 add-on), BT Technologies dovetail bar ($150 add-on) (has a blemish but is super solid), Astrozap dew shield and cap with focus mask ($175 ad-on), Precise Parts Tak corrector to M48 adapter ($110 add-on), the Takahashi collimation tools, an M68x1 male to M54x0.75 female and a M54x0.75 male to 2" compression ring adapter ($100? add-on) (these allow you to use the scope visually with 2" eyepieces.)
I replaced the stock focuser (included) with an Optec TCF-Leo focuser with temp probe. With the included scope adapter and Tak corrector adapter this is a $1400 add-on.
Total new cost = £5900
All of this for £3155 plus shipping.
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.
