Apollo 17 Landing site. Meade 14" ACF and ASI 174MM. Seeing was too bad for using any Barlows. Would like to do colour at some point. Still learning this scope and camera combination. Have not got it right as yet.

+1 Wondering this myself too. EDIT: Seeing was dreadful last night so don't beat yourself up if your concerns are on the basis of last night's efforts.

Indeed, on the MESU I mostly have pancake flat guide graph. But there are many nights here where the guiding is all over the place. From my records on a decent night i get abou 0.2arcsec RMS on the MESU. The NEQ6 is not as good - as it wouldn't at a fifth of the price - but still very, very good. 0.5 RMS.

My imaging scale with the G2-8300 and Samyang 135mm is 8.3 arcsec per pixel. I get guiding accuracy of 0.5 arcsec on the NEQ6 with the small guidescope which is well within half (4.15" in my case) of the optimal Nyquist sampling rate for guiding. I'd like to get a different mount for the above widefield so I can repurpose the NEQ6 for something else (my FSQ85 and a new camera) So this CEM25P at +/- 10Sec is an *unguided* figure ??????? If I guided it I could get a better figure?

£1500 for the CEM25-EC. I was expecting a lot less than that...... Will be keeping the NEQ6 in this role for now then. I then get a free weight training workout every time I do my wide field then

I think I am free for the 2187 one

Looks like a complete write-off weather wise in the UK from the long range forecast..... as per ususal with any exciting astronomical event.

Yeah, I am looking for a somewhat lighter arrangment than the NEQ6 all the time too. I think it will be too heavy for a Star Adventurer. I am using a G2-8300 with Samyang, with guidesciope and autofocus. It weighs in at about 6 KG. Great image to the OP by the way!

Bought me an Astrozap 1.25" dew heater tape for my 50mm guidescope on my wide-field rig No more fogging up.

Yes I agree. I have a mount top fuse panel/distribution panel to feed the 12v from my PSU to the various pieces of gear fused at different amperage. However, the fuses will blow due to over-current, not a transient spike in voltage. So this is no protection. As James also says, the switch at least eliminates a 12v 2.1mm plug hanging in mid-air, waiting to short in some crazy, unanticipated way or on a slew. Remember the old adage; if it can go wrong, it will.... This is actually one of the main reasons I like big batteries. There is no way the battery can output a spike above 12.8v, whereas a PSU, if on its way out and cream-crackered, can. So even though I am using a proper Farnell PSU, I am still thinking of using a crowbar circuit across the 12v outputs, unless these PSU's already have such a thing in their design?

Thanks Ron. Kind of you to say.

Hello all, Here is my M13 with data from summer. 15 x 10 minute luminance and 14 x 5 minutes each of RGB. All with TEC140 refractor at F7 and Atik 460 CCD with Baader LRGB filters atop a MESU 200. I hope you like it. Steve ________________________________

Yep thats the problem with these big, large diameter tubes. In terms of sheer dead weight to lift, not so bad. Bt they are large diameter and hard to grapple with whilst trying to get the dovetail into the saddle - especially on your own.

Hi, say hello to Brazil and Rio and Sau Paulo for me, worked there many years ago for a year and I loved it! welcome to SGL.

Quit worrying about little things like this and enjoy your system is my advice to you.

14 each of RGB binned 1x1 G2-8300 and Astrodon filters. Rarely see these clusters like this with the background nebulosity of the Perseus spiral arm. M36 bang in the middle. I am doing a 15x15 degree high resolution mosaic of this fascinating area.

Three hours Ha (3nm) and 75 minutes each of RGB. G2-8300 Astrodon filters. Everything binned 1x1. October 2019. I opened the lens up to F2.8 but I've lost the corners slightly so need to go back to F4 I think. I know this is a very popular target in the SHO Hubble Pallet but I wanted my version to be HaRGB. Most examples of this are very red so I developed my image similarly.

Very good. A new one on me is that.

Very nice. Your next mission, should you choose to accept, is the same with Sirius and The Pup 🐶😀

Very nice mate, some lovely details in the galaxy.

Lovely edge on galaxy in Pegasus, 45 million light years away. TEC140 and Atik 460. Four hours luminance binned 1x1 and 75 minutes each RGB. Quite difficult to process because not a lot to go on such as no spiral arms etc, just the dust lane. I feel there is more in this data set than I have managed to process out and shall look again. I could not get a lot from my luminance considering how much I got.

In the comments section the comments from people are largely very positive about the guy and largely supportive of him and his obs.

Drive to a farm field gate in a darkish area and set up there. That's what I have done. Highly unlikely the farmer will want access to the field after dark. You may get plod occasionally pull up and ask what you are doing (oh sorry, I forgot, we don't have police that actually drive around anymore do we?)

That is a very nice picture. You could get some quick 2x2 RGB (say 8 x 5min per filter) and make a spectacular colour image out of that data blending the Ha in as the lighting layer on top of the RGB.
