The simplest way is to have a separate little telescope, called a guidescope, with a small camera attached to it. The purpose of this duo is to watch the stars very carefully; any movement could indicate that your mount isn&#8217;t tracking accurately enough. The camera can then communicate with your mount using whichever software you favour (I use an <a href=\"https:\/\/urbanastrophotography.com\/staging\/7355\/review-asiair-plus\/\" type=\"post\" id=\"1096\" target=\"_blank\" rel=\"noreferrer noopener\">ASIAIR Plus<\/a>), and then correct the error in real-time.

The main one is called differential flexure, which is when the guidescope moves a little (numerous things can cause this) and the whole system gets confused. Also, balancing a telescope becomes more difficult when you&#8217;ve got a guidescope attached off-centre. And guidescopes have wider imaging angles (i.e. lower focal lengths) than main telescopes, meaning their data is coarser.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The general rule of thumb is that guidescopes are generally ok for wide-field telescopes (say, under 800mm or so). Beyond that and you&#8217;ll likely run into these hurdles. At this point you may be better ditching the guidescope and going for another approach: the Off-Axis Guider, or OAG for short.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These fit into your imaging train and use a prism to divert a little bit of light from your telescope into the guidecamera. This neatly solves the problems of a guidescope; specifically, no differential flexure, easier telescope balancing, and your guidecamera sees high quality data (as it&#8217;s using light collected from your main telescope).  <\/p>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6aafc68bc1b09&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6aafc68bc1b09\" class=\"wp-block-image size-full wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"2560\" height=\"1707\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on--pointerdown=\"actions.preloadImage\" data-wp-on--pointerenter=\"actions.preloadImageWithDelay\" data-wp-on--pointerleave=\"actions.cancelPreload\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/i0.wp.com\/urbanastrophotography.com\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?fit=2560%2C1707&amp;ssl=1\" alt=\"Side view of an Askar M54 Off-Axis Guider\" class=\"wp-image-11635\" srcset=\"https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?w=2560&amp;ssl=1 2560w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?resize=300%2C200&amp;ssl=1 300w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?resize=1024%2C683&amp;ssl=1 1024w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?resize=768%2C512&amp;ssl=1 768w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?resize=1536%2C1024&amp;ssl=1 1536w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?resize=2048%2C1366&amp;ssl=1 2048w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?resize=500%2C333&amp;ssl=1 500w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?resize=800%2C533&amp;ssl=1 800w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?resize=1280%2C854&amp;ssl=1 1280w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?resize=1920%2C1280&amp;ssl=1 1920w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?resize=507%2C338&amp;ssl=1 507w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/Askar_OAG_2_UAres_watermarked.webp?w=1760&amp;ssl=1 1760w\" sizes=\"auto, (max-width: 880px) 100vw, 880px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\tdata-wp-bind--aria-label=\"state.thisImage.triggerButtonAriaLabel\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.thisImage.buttonRight\"\n\t\t\tdata-wp-style--top=\"state.thisImage.buttonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Sounds good, so what&#8217;s the downside? Well, your guidecam will have a smaller field of view than if you were using a guidescope, due to the longer focal length. So, you need a guidecam with a decently-sized sensor.

This was a reason I opted for the Askar OAG and not the ZWO equivalent; that one doesn&#8217;t come with all these adapters. And, wouldn&#8217;t you know, I did need some of the kit that Askar bundled with theirs. It&#8217;s really annoying when you need to buy extra adapters, and I appreciate Askar&#8217;s approach here: just throw loads of useful things in the box.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"2560\" height=\"1810\" src=\"https:\/\/i0.wp.com\/urbanastrophotography.com\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?fit=880%2C622&amp;ssl=1\" alt=\"Image of an Askar M54 Off-Axis Guider with the included accessories: M54 frontal gasket, M48 telescope adapter, M42 telescope adapter, M54 camera adapter, M48 camera adapter, M42 camera adapter\" class=\"wp-image-11643\" srcset=\"https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?w=2560&amp;ssl=1 2560w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?resize=300%2C212&amp;ssl=1 300w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?resize=1024%2C724&amp;ssl=1 1024w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?resize=768%2C543&amp;ssl=1 768w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?resize=1536%2C1086&amp;ssl=1 1536w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?resize=2048%2C1448&amp;ssl=1 2048w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?resize=500%2C353&amp;ssl=1 500w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?resize=800%2C566&amp;ssl=1 800w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?resize=1280%2C905&amp;ssl=1 1280w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?resize=1920%2C1357&amp;ssl=1 1920w, https:\/\/i0.wp.com\/urbanastrophotography.com\/staging\/7355\/wp-content\/uploads\/2026\/02\/image-2-scaled.png?w=1760&amp;ssl=1 1760w\" sizes=\"auto, (max-width: 880px) 100vw, 880px\" \/><figcaption class=\"wp-element-caption\">Credit: Askar.<\/figcaption><\/figure>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">So after all that I had the Askar OAG and guidescope attached, as shown below.

The prism is on a kind of metal stalk, and the OAG comes with an Allen key that can be used to loosen a screw that holds this stalk in place. It&#8217;s then a simple procedure to adjust its height. After a few trial-and-error attempts, I had it perfectly positioned.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Next comes focussing. The first step here is to ensure that your main imaging camera is in focus. Then, you need to physically move the guidecam higher and lower until it too is in focus. The Askar M54 OAG comes with a helical focusser that allows for precision fine-tuning of the focus, and this makes things easier. The general advice is to do as much of this as you can during daytime, by pointing your telescope at something on the horizon, like a distant house chimney. Then you&#8217;re in the ball-park, and can do your fine tuning at night under the stars.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And that&#8217;s about it for set-up. Some good news: once that&#8217;s all done, you basically lock things down and never think about them again.<\/p>\n<\/div><\/div>\n\n<\/div><\/div>\n\n<style>.kb-row-layout-wrap.wp-block-kadence-rowlayout.kb-row-layout-id11624_6f4757-73{margin-top:var(--global-kb-spacing-md, 2rem);}.kb-row-layout-id11624_6f4757-73 > .kt-row-column-wrap{align-content:start;}:where(.kb-row-layout-id11624_6f4757-73 > .kt-row-column-wrap) > .wp-block-kadence-column{justify-content:start;}.kb-row-layout-id11624_6f4757-73 > .kt-row-column-wrap{column-gap:var(--global-kb-gap-md, 2rem);row-gap:var(--global-kb-gap-none, 0rem );max-width:900px;margin-left:auto;margin-right:auto;padding-top:var(--global-kb-spacing-sm, 1.5rem);padding-bottom:var(--global-kb-spacing-sm, 1.5rem);grid-template-columns:minmax(0, 1fr);}.kb-row-layout-id11624_6f4757-73{border-top-right-radius:50px;border-bottom-left-radius:0px;overflow:clip;isolation:isolate;}.kb-row-layout-id11624_6f4757-73 > .kt-row-layout-overlay{border-top-right-radius:50px;border-bottom-left-radius:0px;}.kb-row-layout-id11624_6f4757-73 > .kt-row-layout-overlay{opacity:0.30;}.kb-row-layout-id11624_6f4757-73 ,.kb-row-layout-id11624_6f4757-73 h1,.kb-row-layout-id11624_6f4757-73 h2,.kb-row-layout-id11624_6f4757-73 h3,.kb-row-layout-id11624_6f4757-73 h4,.kb-row-layout-id11624_6f4757-73 h5,.kb-row-layout-id11624_6f4757-73 h6{color:#ffffff;}.kb-row-layout-id11624_6f4757-73 .kt-row-layout-bottom-sep{height:100px;}.kb-row-layout-id11624_6f4757-73 .kt-row-layout-bottom-sep svg{width:100%;}.kb-row-layout-id11624_6f4757-73 .kt-row-layout-bottom-sep svg{fill:#ffffff!important;}@media all and (max-width: 1024px){.kb-row-layout-id11624_6f4757-73 > .kt-row-column-wrap{grid-template-columns:minmax(0, 1fr);}}@media all and (max-width: 1024px){.kb-row-layout-id11624_6f4757-73 .kt-row-layout-bottom-sep{height:px;}}@media all and (max-width: 1024px){.kb-row-layout-id11624_6f4757-73 .kt-row-layout-bottom-sep svg{width:%;}}@media all and (max-width: 767px){.kb-row-layout-id11624_6f4757-73 > .kt-row-column-wrap{grid-template-columns:minmax(0, 1fr);}.kb-row-layout-id11624_6f4757-73 .kt-row-layout-bottom-sep{height:px;}.kb-row-layout-id11624_6f4757-73 .kt-row-layout-bottom-sep svg{width:%;}}<\/style><div class=\"kb-row-layout-wrap kb-row-layout-id11624_6f4757-73 alignnone has-eighty-black-background-color kt-row-has-bg wp-block-kadence-rowlayout\"><div class=\"kt-row-column-wrap kt-has-1-columns kt-row-layout-equal kt-tab-layout-inherit kt-mobile-layout-row kt-row-valign-top\">\n<style>.kadence-column11624_b8fa5f-8f > .kt-inside-inner-col,.kadence-column11624_b8fa5f-8f > .kt-inside-inner-col:before{border-top-left-radius:0px;border-top-right-radius:0px;border-bottom-right-radius:0px;border-bottom-left-radius:0px;}.kadence-column11624_b8fa5f-8f > .kt-inside-inner-col{column-gap:var(--global-kb-gap-sm, 1rem);}.kadence-column11624_b8fa5f-8f > .kt-inside-inner-col{flex-direction:column;}.kadence-column11624_b8fa5f-8f > .kt-inside-inner-col > .aligncenter{width:100%;}.kadence-column11624_b8fa5f-8f > .kt-inside-inner-col:before{opacity:0.3;}.kadence-column11624_b8fa5f-8f{position:relative;}@media all and (max-width: 1024px){.kadence-column11624_b8fa5f-8f > .kt-inside-inner-col{flex-direction:column;justify-content:center;}}@media all and (max-width: 767px){.kadence-column11624_b8fa5f-8f > .kt-inside-inner-col{flex-direction:column;justify-content:center;}}<\/style>\n<div class=\"wp-block-kadence-column kadence-column11624_b8fa5f-8f\"><div class=\"kt-inside-inner-col\"><style>.wp-block-kadence-advancedheading.kt-adv-heading11624_9dbf1a-5c, .wp-block-kadence-advancedheading.kt-adv-heading11624_9dbf1a-5c[data-kb-block=\"kb-adv-heading11624_9dbf1a-5c\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading11624_9dbf1a-5c mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading11624_9dbf1a-5c[data-kb-block=\"kb-adv-heading11624_9dbf1a-5c\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading11624_9dbf1a-5c img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading11624_9dbf1a-5c[data-kb-block=\"kb-adv-heading11624_9dbf1a-5c\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h3 id=\"askar_m54_oag_in_use\" class=\"kt-adv-heading11624_9dbf1a-5c wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading11624_9dbf1a-5c\">Askar M54 OAG in use<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The results are really good, and the Askar M54 OAG performs as advertised.
