Mars was taken at night between 20:57 and 22:29 UTC. Equipment used: Celestron SCT C8, Barlow 2x, GSO #29 (dark red), ASI120MM Mini, HEQ5 mount. Animation was prepared from 20 images with drizzle 150% (the best 10% of frames from 60-second movies): One of the best images from 21:55UT:

I had my C8 SE out for some visual observing but did not get much done (full moon). There was some action at Jupiter so I put the ASI224MC and the ADC on to take some images. 5000 frame videos, processed best 20% with Registax6. The result was better than I expected with Jupiter at an altitude of 14 degrees. The image shows the Great Red Spot, some nice cloud detail, the shadow of Io and there ought to be a transiting Io there somewhere.

Here is an image of Jupiter, taken around 6am on 15 Feb with my C8, ASI120MC, +ADC, processed in Registax6 from around 30% of 3000 frames. I am fairly pleased with it considering that the altitude of the planet was only about 12 deg. and the seeing looked bad when I tried to focus on a star. And it shows the Great Red Spot.

I had another go at imaging the shrinking Mars, this time without and with a x2 Barlow lens. The results are better with the Barlow, which is what one is led to expect. For whatever reason (probably bad seeing and/or low planets) when I tried a Barlow previously it just made the blur bigger. Equipment: C8 SE, ASI120MC, x2 Skywatcher kit Barlow element screwed directly into 1.25" barrel of the ZWO camera. This does seem to give x2 in practice. I did not use an ADC on the grounds that I shouldn't need one with Mars at an altitude of over 40 degrees. 3000 image video captured with Sha

Here is an image of Mars I made on 9 Jan this year, with a C8 SE, and ASI120MC camera. The images are rather small (around 7" dia). Mars is now much higher in the sky than at opposition, so it seemed worth taking a few farewell images as it diminishes in size. Captured with Sharpcap. I did not use the ADC - the images are corrected for AD in the processing in Registax. This is from a run of 3000 images. I have included a x3 Photoshop zoom of the same image to indicate the size of Mars at opposition on the same scale. I was quite pleased to record some surface detail, corresponding wi

It is not often in the UK that we have a bank holiday weekend, a new moon and a clear sky at the same time. Last night was one of those rare occasions! The forecast (Clear Outside) was not very definitive about the cloud cover, but from looking at the satellite images and from experience, I thought this could be a magnificent sky as we were on the backside of the last weather front. So, I thought – let’s give it a go, we could be rewarded. By 9pm the car was packed with the C8 and my trusty Vixen SP-DX. A quick check on my friend Steve, and yes, he was up for it, too.

I have continued to image Mars as it moves away. It is getting smaller, but on the other hand I don't have to get up in the middle of the night, the dust storm has subsided, and it is gaining significantly in altitude. Here is a series of images taken in September and early October, all taken with a C8 SE, ASI120MC, +ADC, processed in Registax 6. The seeing was often poor, but seemed better on Oct 3.

Having a bit of a clear out. For sale an ADM mini dovetail system for attachment to a C8 but can be used for other telescopes, after the right mounting blocks are purchased - same as this one here - https://www.rothervalleyoptics.co.uk/adm-mini-dovetail-system-guidescope-kit.html Asking £75, new price as its unused - a couple of scratches when fitting to test it but never used in anger - retail is £147. Both sold Revelation Astro 8 inch losmandy plate, with all the required holes for mounting a myriad of rings and scopes - games as these ones here - ht -
Seeing as close to opposition I felt I needed to make the effort and stay up late ! Managed this last night / this morning while Saturn was popping in and out of view between various obstructions. Quick process of 2 minute AVI captured in Sharpcap, raw8, 3000 frames, pipped to 70%, then Autostakkert best 25 %, RGB align and wavelets in Registax 6, colour and contrast tweak in CS2. Thanks for looking... very tired at desk in office ? C8 Edge / Televue 2 x barlow / ASI 224MC

For once I set up my two catadroptic imaging scopes together to see how they compared, and how well the smaller one cut through the crud. C8 SCT on SE mount, ASI 120MC, ADC, processed in Registax6, 3000 frame video. Celestron 127mm Mak on Nexstar SLT mount, wood tripod, ASI120MC , ADC, processed in Registax6, 3000 frame video. The 127mm images are slightly smaller, placed second. The bigger scope seems to do better. I thought that Saturn did not change much and was just a seeing test target, but the shadow of the planet on the rings is now distinctly asymmetrical. The dark

First time out of back garden since damaging shoulder in December ( thankyou @Blazar ) took this at around 01:30 so really 29th not as in title. Seeing was way better than my back garden but still pretty poor due to low altitude. Roughly 4 minute 8000 frames, Pipped to 80 % then Autostakert best 25 %. Fairly aggressive wavelets in Registax. Thanks for looking.

First night in back garden for what seems like forever, had an interesting session. Set the C8 on Jupiter while I dabbled with the star adventurer mini / Nikon D5300 / 105 2.8 macro. Tried too many things as failed miserably on focus with the D5300, Jupiter was just clearing neighbours roofs ... Got quite disheartened by 3am so took cameras off and had a peak at M13 before packing up. Absolutely beautiful ! C8 with ES 14 mm. Thought I'd try imaging it but only had the Nikon with William optics flattener attached ... Managed 20 x 15 seconds as hadn't polar aligned

Mars imaged around 1.30 AM BST. Seeing poor, altitude about 12 deg, Mars just above a roof, had to wait for gap in cloud. Using: C8 SE, ASI120MC, ADC, best of 2000 frames, processed in Registax6. Some surface detail and a polar cap can be made out, confirming visual observation.

Dusted off the scope last night to check if everything is working ok, aimed for a quick bash at Jove, then some fiddling with the OAG setup using M13 as target. Attached is Jupiter at around 1030 with Io bottom left. I was quite pleased as only had 2 runs of 3 minutes before moving onto the guiding practice which went 'badly'

Hi all. Sharing my capture of Jupiter from 19 April 2017. The video comprises frames from 1622UT to 1718UT and shows the GRS traversing the planet. Video can be viewed at either the youtube or attachment link below. https://youtu.be/8M7d3m34c5I 2017-04-19-1622_1-RGB_pipp_x264.mp4 Equipment used: Celestron C8, QHY5L-II-C, GSOx2.5barlow -
Hi. I have a baader zoom ii and 32mm plossl which i use loads with my c8. Just for visual and 1.25. A WO dialectic diagonal just because it was really cheap second hand and a Barlow which I never use because the magnification is high enough with a focal length of 2000mm. Is there anything I'm missing that might be really useful? I'm thinking about the 6.3 reducer and or a 40mm plossl, but I'm not really sure if I'm going to feel the benefit or not. Advice welcome please. It's so easy to own seldom used kit in this hobby. Thanks TimB

Hello all, Due to the rain and clouds I reprocessed the Sculptor and Helix Nebulae. A mate came over and found a astrophotography processing method in photoshop using the "high pass" filter... I gave it a go and it seems like I got a bit more detail out of the Sculptor Galaxy and Helix Nebula data... What do you astronomers think... improvement or too much? Thanks for looking, MG

The postman, well DHL delivery guy, bought a few sizeable packages this morning. After waiting a month for an AYO II from Switzerland, only to find out it was going to be another 4-5 weeks lead time, I had to cancel the order as I am currently mountless and booked in for the SWAG Star Party end of March. Instead, I placed an order for an Altair Sabre V2 with dual vixen saddles from Harrison telescopes which were all in stock. I also took advantage of the Celestron spring sale and thanks to the guys @FLO for splitting out a C8 Evolution OTA for me. I could have had a standard C8 but I

Whilst carrying out a star test I have noticed with a friends C8 that one side of focus appears to be collimated and the other side of focus its off, is this a common problem? Is his best option to collimate as an average so its slightly off either side?
-
Found an old (apparently USA model) celestron C8 SCT a while back, its a bit hit n miss with collimation and the optics - (some very strange star test shapes :P) but when it works it works well Here is a couple images from a couple months back. Thanks for looking. This particular night seeing was reasonably good, and collimation wasn't too bad either.
