ZWO ASI224 vs ASI290mc
johninderby replied to MimasDeathStar's topic in Getting Started With Imaging
This should help. Includes a calculatorfor working out the right pixel size for your scope. Has the ZWO cameras in the calculator. https://astronomy.tools/calculators/ccd_suitability -
Why would it put too much strain on the ring? If it is a CNC tube ring will be plenty strong enough for use with a refractor.

A carry handle like this StellaMira one would do but not available seperately as far as I know. Ypu could fry asking FLO if they could get one for you. Or there is this Vixen one in white. https://www.amazon.com/Metal-Carry-Handle-for-Refractors/dp/B0017WXO26

The AZ-GTi mount simply fastens directly to the 3/8 tripod. No mods needed.

Tele Vue Apollo 11 Special Edition Eyepiece

Most of the Apollo eyepieces will probably spend their time in a display case untouched by human hands. 😢 -
Tele Vue Apollo 11 Special Edition Eyepiece
johninderby replied to johninderby's topic in Discussions - Eyepieces
They are 1.25” and a great bargain at the price. I have the 7mm and 16mm myself. Go nicely with my Nagler 3-6 zoom. https://www.firstlightoptics.com/ovl-eyepieces/ovl-nirvana-es-uwa-82-ultrawide-eyepieces.html -
Tele Vue Apollo 11 Special Edition Eyepiece
johninderby replied to johninderby's topic in Discussions - Eyepieces
The OVL Nirvana 82 degree eyepieces (4, 7, 16mm) would work really well in a 200p and would work nearly as well as Naglers. -
I see it as making an informed decision. Weigh up the costs vs benefits and then decide. Unfortunately it's so easy to spend more than you really need to. Now the OP can have a think about it and decide what they want to spend. There certainly is nothing wrong with buying a 200P and keeping the costs to a minimum for now.

The StellaMira 104mm or 85 perhaps? https://www.firstlightoptics.com/stellamira-telescopes/stellamira-104mm-ed2-triplet-f6-25-apo-refractor-telescope.html https://www.firstlightoptics.com/stellamira-telescopes/stellamira-85mm-ed2-triplet-f6-6-apo-refractor-telescope.html

Tele Vue Apollo 11 Special Edition Eyepiece Just curious if anyone has bought one. Has FLO sold any? And no I won’t be buying one at that price. 🙀 https://www.firstlightoptics.com/tele-vue-eyepieces/tele-vue-apollo-11-special-edition-eyepiece.html

Yes I was thinking about the 10” Bresser. The R&P will handle more weight as the R&P drive is more positive. I think as the Skywatcher has been around for ages most are familiar with it but with the Bresser being new not many have actually seen one in person and it’s not until you’ve had hands on experience with both that you can appreciate the differences.

Why do (some) Astro vendors list unavailable items!?...
johninderby replied to parallaxerr's topic in The Astro Lounge
Items offered for sale online are often actually drop shipped from the distributor not the retailer and if the distributor has not updated stock levels the retailer may be going on the distributors out of date info. Hence buying from someone like FLO that actually stocks the items themselves and doesn’t use drop shipping. -
Few other points in the Bresser’s favour. Rubberized anti refection coating on the inside not just a thin coat of paint. Proper 6 point mirror cell Adjusment knobs on the secondary not just hex screws. Tube rings allow the OTA to be moved up or down for balance Tube rings allow the focuser to be rotated into the most convienient position The alt bearings make great carry handles and also the OTA just drops into place on the base with no need to insert knobs . Being collaoseable not needed in an 8” dob and is lighter and easier to carry. Collapseable makes more sense with bigger dobs.
-
Once you’ve actually seen the Bresser dob in person it’s game over for the Skywatcher. The Bresser is just so much better in build quality and features. You would spend more upgrading the Skywatcher than just buying the Bresser in the first place. You really should try to see both in person and then make up your mind.

I would stay away from anything with an EQ2 mount. Minimum should be an EQ3. The EQ2 just won’t be very stable. Of course the EQ3 is more expensive but skimpimg on the mount is a false economy. The 8” dob will show a lot more than the 130 and is so easy to use. Good reason that size is so often recommended. The Skywatcher dob is OK but if your budget will stretch to it the Bresser 8” dob has better build quality and is better equipped. You do get what you pay for. https://www.firstlightoptics.com/bresser-telescopes/bresser-messier-8-dobsonian-telescope.html or https://www.harrisontelescopes.co.uk/acatalog/bresser-messier-8--dobsonian-telescope-4716420.html#SID=1684

Yes a berrer equipped scope and very nice quality scope. Well worth the extra for the 8” or 10”.

Camera FV-5 Pro has an intervalometer option as well as long exposures etc. and histograms in RGB or luminance.

Did use Open Camera but now moved to Camera FV-5 Pro. Just so much easier to use with more options and makes Open Camera look rather primitive and clumsy in comparison.
