No it wouldn't! I think you maybe confusing camera lenses with telescopes. View the same object at the same size in each telescope and it would be exactly the same brightness. Equally: image the same object using the same camera at the same size and you would need exactly the same time on both telescopes to record it equally. As @vlaiv recommends, don't say 'fast' [1] Cheers, HTH and clear skies. [1] but if you do, then please say what your definition of fast be;)

Very much inspired by your article on Newtonian modifications and in particular the long-strong dovetail😉 I wonder just how many Newtonians are rejected -astrograph potential wise- for having inadequate tube support afforded by their tiny narrow dovetails? Cheers

If the top of the tube is at 10-o'clock, and you have an f4-f5 telescope, good. HTH.

No mention of cameras. Phew, that was close! Hi If a fast telescope is one which collects a lot of light, then no. A 200mm diameter f6 telescope collects more light than an 80mm f6 telescope, so the former is faster. AFAICT, that's it. HTH

Hi everyone I put a proper dovetail and top rail on this -not so- little gem and it now looks and acts the part. No cc, filter or other glass to distort reality; just add camera nose-piece and go. The extra weight of the dovetail was offset by using an oag, although I think that with the modifications, you may get away with a guide telescope. No blue stars though. Again! At this fl, monkey-head nebula should fill the frame. That's the next target I think... Thanks for looking and let's not forget the ability of the humble Newtonian. Who knows, we could even have a 6"-f8 thread; I've seen a few other -IIRC 150pl- users on the forum... 700d, nt150L, 60 minutes

Hi everyone We're getting on for 18 moths now. Just checking back to see if anyone has managed it yet. Cheers, merry xmas and clear skies.

Hi. The coma corrector needs to be further from the sensor, either 56.0mm or 58.5mm. This depends upon whether you are using the supplied m42 adapter or the m48 thread on the coma corrector itself: HTH

Hi. Phew, €64 plus shipping?! But they look interesting. The one used in the guide is this one. Not sure it's as accurate as @Starflyer's though. HTH

Hi A light -not all pixels set- mask over the witch under isolate in the life module should bring it forward. HTH

LOL, no one would dare because there's sure to be someone come along and point out why it's not perfect! With that in mind, please see below my perfectly collimated reflector. But seriously, it doesn't have to be perfect. The secondary mirror is simply a flat bit of glass; get it somewhere near and then leave it. But before you adjust anything, be sure to read the collimation myths. They'll clear much confusion and save you a lot of time. HTH and clear skies.

Hi. If it's this one then it's a big yes, but it's of limited use unless you can get it onto a -preferably equatorial- tracking mount. The build and optical quality of the Bresser reflectors is excellent. You also get a proper focuser and tube rings. HTH

It reminds me of the guy who'd been trying for hours but still couldn't get his DSLR to connect to his telescope. He then saw how my DSLR coupled with ease. His immediate reaction was to ask me how much a new Canon would be. Yeah, you need to think about it!

Moon-limited to short frames, perhaps not the right time to image this but anyway, quite a few galaxies popped out. The short exposures seem to help with the colour. This is probably worth doing on a darker night with longer frames. All comments most welcome and thanks for looking. 700d on ES pn208

Alas, I believe we have not escaped entirely; Auriga seems awash with it...

Hi everyone Fast reflector and 90% moon? At f3.9, not quite up there with the RASA (one day maybe!) but something to think about for the current bright nights perhaps... The first time I've managed proper blue stars over so many targets. All comments most gratefully received and thanks for looking. ES pn208: 1 hour each

Hi There's something of nebulosity around the stars of the cluster but also maybe haze, cloud or walking noise over the whole frame. The background is going to be difficult so just to answer your question... Don't know what you're using to process but if by conventional means, go a bit at a time with the centre slider. HTH

Hi It's probably larger than the forum limit, so best to upload it to e.g. Google Drive or Dropbox and send us the link. Cheers

There are two cables listed. Both are from AliExpress. One of them is wired so that it connects the mount directly to your computer, eliminating the handset. The other does the same but keeps the handset. I'd recommend the former. It is called an eqmod or eqdir cable. You don't have to obtain either from AliExpress. It just works out a lot cheaper that way. HTH

Makes it easy... http://forum.startools.org/viewtopic.php?f=12&t=1148 Make separate lrgb stacks in DSS first. HTH

I'll reluctantly give you the bin bag. However your elastic band looks positively professional. Call it quits?

Hi. yes. Note, there's an elastic band to hold it in place. These design types seem to have made the diameter of the cap stretch to the size of an average human head, with little regard for preventing light entering the mirror cell of a 130pds. Ridiculous.

Hi Yes. The easiest way is then to lose the handset and instead connect the mount to the computer using this cable. If you want to/must keep the handset, then one of these. Then as @Merlin66..describes above. HTH

Any good? https://www.ebay.com/itm/M4-x-12mm-Toolless-Thumb-Screw-Stainless-Steel-/201713636023?_ul=ES

Hi I agree. There's only one other I'd consider. It has the same optical specification: this one, which is built to last. HTH

Hi. Meanwhile, at the budget end of the range, a black shower cap. 3 for €1. Elegance defined!
